Material
Lacquered brass
Also stated
trade catalog reference
Two published lines, and the material is the interesting one.
What the manufacturer publishes
A plumb bob in lacquered brass.
Why brass rather than steel
Density. Brass is roughly ten per cent denser than steel, so a bob of a given mass is smaller — and a smaller bob hangs down a narrower gap without touching the sides, which is exactly the situation where a plumb bob is being used instead of a laser.
The lacquer stops tarnish, which otherwise transfers to the line and to whatever the bob is resting against.
What is not published
The mass. It is the specification that decides how quickly the bob settles and how much a draft moves it, and it is not in the listing. The Alyco in this hub states 500 g (17.6 oz); this states its material and stops.

What gets asked here
Brass or steel?
Brass is denser, so for the same weight the bob is smaller — which matters when it has to hang down a narrow gap without touching. Steel is cheaper for the same mass.
What weight is it?
The listing does not state it, which is the specification a plumb bob is chosen on. The Alyco in this hub states 500 g (17.6 oz).
Does it come with a line?
Not stated. The kwb mason line in this hub is the obvious companion, and it publishes its strength.
The only actual line on a shelf called mason lines and plumb bobs — braided, orange, two hundred and fifty feet.
Stated dimension or range
250 FEET per reel, three reels. Every other product on this shelf carries between 10 and 14.5 feet of cord and six of the seven are bobs — so this is the only line on the shelf in any meaningful sense, and it carries seventeen times the length of the longest bob cord here
Material
BRAIDED, stated in the title, and ORANGE. Both are the things this shelf's introduction asks for: braided line resists the stretch that makes a twisted line sag differently at each setting, and bright colors stay visible against rubble. A twisted line also unwinds under tension and rolls a brick course off true as it does
Body and fittings
A line reel handle of durable polyethylene, stated, with the line securing in a convenient notch. It is a hand reel rather than a retracting one — the notch is what stops the line unwinding in a bag, and it is the whole mechanism
Supplied
Three reels at eight dollars seventy-nine — about two dollars ninety a reel of 250 ft. Three is the right number for a trade that loses line: one on the job, one in the van, one cut short and still useful
Also stated
TWO bullet points, and that is the whole listing. No breaking strain, no diameter, no material beyond braided, and no stretch figure — this shelf's introduction compares line STRENGTH and STRETCH, and neither appears
Functions
Not published: no twine size, no number, no weight. Mason's line is normally specified by a number — a #18 or #21 — which sets its diameter and breaking strain, and this listing gives none

250 feet, where every bob here carries ten to fifteen
Braided, which the hub intro says resists stretch
Two bullet points, and that is the whole listing
Best for: Setting out brickwork, fencing or a long datum, where a bob's ten feet of cord is nothing
The heaviest bob here, and the only one with bumpers to stop it marking the wall it hangs against.
Stated dimension or range
21 oz / 600 g — the heaviest bob on this shelf, where the lightest is 5 oz: a factor of four. This shelf's introduction says weight sets how quickly a bob settles and how little it swings in a draft, which makes this the bob for an open site, a stairwell or a long drop
Measuring mode
Quick-stabilizing: stops wobble AND SPIN within 6 seconds, stated. The same figure as the maker's 10-ounce bob on this shelf, which is the interesting part — doubling the weight does not halve the time, because the design rather than the mass is doing the work. Spin is the half nobody else mentions: a bob that has stopped swinging can still be rotating, and a rotating bob with an off-center tip traces a circle
Body and fittings
EMBEDDED SIDE BUMPERS, stated to protect both the bob and the work surfaces. Nobody else on this shelf has them, and they solve a real problem twice: a 600 g (21.2 oz) steel bob swinging into a finished wall marks it, and the same impact chips the bob's own plating
Functions
A thick ELASTOMER TIP GUARD, stated to keep the tip safe and secure. The tip is what a bob dies of — one drop rolls the point over — and a guard is the other answer to that problem; the brass kit on this shelf answers it with four spare tips instead
Material
Chrome plated to resist rust and corrosion, stated. Chrome is harder than nickel and resists the chip that starts the rust — which matters more on a 600 g (21.2 oz) bob, because a heavier bob hits harder when it is dropped
Supplied
A snap ring as standard, to connect and disconnect from a plumb line, stated. A snap ring rather than a knot means the same bob moves between a short line and a long one in seconds. NO LINE IS SUPPLIED — this is a bob, not a kit, and the shelf carries 250 ft of braided mason's line for under nine dollars

Twenty-one ounces: the steadiest bob on this shelf
Six seconds, and it stops SPIN as well as swing
No line supplied at all
Best for: A long drop outdoors or in a draft, where a light bob never stops swinging
The only bob here that says how long it takes to stop — and the only one you can hammer into a ceiling.
Measuring mode
Quick-stabilizing: the 10-ounce bob steadies WITHIN 6 SECONDS, stated. It is the only settling time published on this shelf. This shelf's introduction says weight sets how quickly a bob settles and the buying tip says to let it stop on its own rather than steadying it by hand — a published six seconds is what makes that instruction bearable, because the alternative is standing there not knowing whether to wait longer
Reference and mounting
THREE fixings in one head, stated: a setting pin for wood and drywall, a strong magnet for steel surfaces, and a hook for nails or studs. No other bob on this shelf offers more than two, and most offer none at all — a bare bob is tied to a nail somebody else put in
Functions
An AUTO-RETRACTING PIN STRIKER, stated for use with a hammer for overhead setting. That is the unusual one: you hold the setter against a ceiling and strike it, the pin drives in, and the striker retracts out of the way — so a plumb line can be dropped from a ceiling without first fitting a nail with a free hand you do not have
Stated dimension or range
10 oz / 300 g, published in both units, with a 14.5 ft self-retracting line. Ten ounces is the middle of this shelf, which runs from 5 oz to 21 oz
Body and fittings
A self-retracting line, stated for quick easy storage. Two bobs on this shelf retract; the rest use a hand reel, a card or nothing. The line construction is not stated — four listings on this shelf state braided, and this is not one of them
Also stated
Commercial grade for long-lasting durability, and described in the maker's own text as a compact and light-duty version. No tip material, no tip guard and no replaceable tip is published

Six seconds to steady, the only settling time here
A setting pin, a magnet AND a hook in one head
The line construction is not stated
Best for: Overhead setting from a ceiling or a steel beam, where the fixing is the hard part
The genuine Klein pipe clamp — and the narrowest temperature range on this shelf, at the highest price of the two clamps.
Type and plug fit
Type K, stated. "Works with any digital multimeter or clamp meter that measures temperature", and Klein adds that its K-type accessories work with all Klein multimeters and clamp meters that measure temperature "as well as any other brand with meters that measure temperature". The banana plug adapter is NOT in the box: it is Cat. No. 69146, sold separately — which matters because this shelf's introduction says the plug is where fit fails
Probe style
A PIPE CLAMP, which is a fourth style this shelf's introduction does not name. It lists a bead for air, a flat pad for surfaces and a sheathed rod for immersion; a spring clamp that closes round a pipe reads the outside wall of a line you cannot immerse anything in. It is the dominant style in the American relevé for this shelf, because that is how a refrigeration circuit is diagnosed
Stated temperature range
−4 to 212 °F (−20 to 100 °C), stated. That is the NARROWEST range on this shelf: the published Taiss states −40 to 350 °C (-40 to 662 °F), the Nxtop 0 to 1100 °C (32 to 2012 °F), the Klein 69142 beside it 0 to 480 °C (32 to 896 °F), and the ZIBOO clamp that borrows this part number claims −40 to 200 °C (-40 to 392 °F). One hundred degrees Celsius is the top of it, which covers a heating flow and stops below a hot gas line
Stated accuracy
±2%, stated — and then the sentence that makes it honest: "Thermocouple accuracy is dependent on the accuracy of the meter being used." Two probes on this shelf publish a figure at all — this clamp and the ZIBOO — and both add that caveat. It is the right way to put it: a thermocouple generates a voltage, and what turns that voltage into a number is the instrument
Cable length
40 inches, 102 cm, flexible. The ZIBOO clamp states 39.78 inches for the same 102 cm (40.2 in), which is the same lead described to two decimal places. The published Taiss five-pack gives 3 m (10 ft), three times either clamp
Clamp capacity
Pipes from 1/4 to 1-3/8 inch diameter. The ZIBOO clamp claims 1/4 to 1 1/2 inch — an eighth of an inch more. Both listings then add "up to 35 cm (13.8 in)", which is not a pipe diameter at all and appears on both pages
Heat resistance
Not stated separately from the measuring range. Klein positions this as the accessory that "extend[s] working temperature ranges for Klein's HVAC Digital Multimeters and Clamp Meters", and names the rest of the family: high temperature thermocouple wire, temperature probe and banana plug adapter

Type K, so it reads correctly on any type K meter
A clamp, which is what a pipe actually needs
A hundred degrees Celsius is the narrowest ceiling here
Best for: HVAC pipe temperatures on small-bore copper, read through a Klein or any other meter with a temperature function
Klein's high-temperature thermocouple — 480 °C (896 °F), a coiled lead, and no stated accuracy or probe style.
Type and plug fit
Type K, stated, and the ADAPTER IS INCLUDED — "with Adapter" is in the product title. That puts it with the ZIBOO clamp and against the Klein 69140, where the adapter is a separate part number. "Works with any digital multimeter or clamp meter that measures temperature"
Stated temperature range
32 to 896 °F (0 to 480 °C), stated. Nearly FIVE TIMES the ceiling of Klein's own 69140 pipe clamp, which stops at 100 °C (212 °F) — and Klein says so directly: these accessories "extend working temperature ranges for Klein's HVAC Digital Multimeters and Clamp Meters". It does not go below freezing, which the two pipe clamps on this shelf both do
Probe style
NOT STATED. This shelf's introduction makes probe style the thing you choose by the job — a bead for air, a flat pad for surfaces, a sheathed rod for immersion — and this listing says only "High Temperature Thermocouple". There is no bead, no pad, no sheath and no tip dimension anywhere on the page, which is the one specification a buyer needs to know whether it will sit on a flue or in it
Stated accuracy
NOT PUBLISHED. The listing gives only the caveat without the figure: "Accuracy of the thermocouple is dependent on the accuracy of the meter being used." Both pipe clamps on this shelf state ±2% alongside that sentence; this one states the sentence alone, at the highest price of the three Klein parts
Cable length
A COILED lead, 3 feet — the only coiled lead on this shelf, and shorter than either pipe clamp’s meter. Coiled matters on a hot job: a straight lead draped across a flue collects heat along its length, while a coil keeps the cable off the work and pulls back out of the way
Heat resistance
Implied by the 480 °C (896 °F) measuring range and not stated separately for the lead. Klein lists "High Temperature Thermocouple Wire" as a DIFFERENT accessory in the same family, which suggests the wire on this part is not itself the high-temperature item
Also stated
11 grams, the lightest probe weight published on this shelf. Klein names the rest of the K-type family on this page — temperature pipe clamp, temperature probe, high temperature thermocouple wire and banana plug adapter — which is the clearest accessory map any maker on this shelf publishes

Four hundred and eighty degrees, five times Klein's own clamp
The adapter is in the box
No accuracy figure at all, at thirty dollars
Best for: Flue gases, hot gas lines and anything above the 100 °C (212 °F) ceiling of Klein's own pipe clamp
