A heavy tripod reaching 295 cm (116.1 in), with a quick-clamp lock instead of screw collars — the difference between setting a height in seconds and in a minute.

Supplied
Quick Clamp height lock
A working height from 122 cm (48 in) to 295 cm (116.1 in), double the reach of the compact tripods here
A Quick Clamp system for fast height locking rather than screw collars
A minimum height of 122 cm (48 in) — it cannot go low for floor work
Best for: Ceilings, high datums and external work, where 175 cm (68.9 in) is not enough.
High stability, with absolutely secure footing on any ground thanks to robust aluminum construction. A Quick Clamp system for rapid height locking. Flexible height adjustment from 122 cm (48 in) to 295 cm (116.1 in).
Two hundred and ninety-five centimeters, and what it is for
Setting a datum at ceiling height, working over a stairwell, positioning a laser above an obstruction. None of those is possible on a 175 cm (68.9 in) tripod, and all of them are ordinary jobs.
And the number at the other end
One hundred and twenty-two centimeters minimum is high. Floor-level work — skirtings, screeds, tiling — needs a tripod that goes down, and this one does not. It is a specialist reach rather than a general-purpose stand.
Availability
No such listing: the American Amazon shop answers the reference with a search box rather than a page.

What gets asked here
Why does the minimum height matter?
Because floor work exists. A tripod that will not go below 122 cm (48 in) cannot set a line for a skirting, a screed or a tiled floor. The compact tripods here start at 60 to 70 cm (23.6 to 27.6 in). If you only own one, that matters as much as the maximum.
What is a quick clamp?
A lever that locks the leg section in one movement, against a screw collar that has to be turned. Over a day of moving a tripod between rooms that is a real amount of time.
Which thread does it have?
The listing does not state it. Bosch construction tripods are commonly 5/8", and the compact lasers in this catalog are 1/4" — check before ordering.
Six feet of height and a level built into the head — and no figure anywhere for how low it goes.
Stated dimension or range
Extends open to 72 in and collapses to 38 in for storage, stated. Seventy-two inches is the tallest on this shelf — six feet puts a laser above head height for a suspended ceiling or a soffit. NO MINIMUM WORKING HEIGHT is published: 38 inches is the folded length for transport, not a usable setting, and this shelf's introduction says the minimum matters as much as the maximum
Reference and mounting
A 1/4-inch × 20 thread mount, stated, and stated compatible with ALL DEWALT line and spot lasers. Naming the whole of its own laser range is a stronger compatibility statement than most on this site — and 1/4 inch rather than 5/8 means it is not a construction tripod
Body and fittings
A tilting head with an INTEGRATED LEVEL, stated to allow level ground to be established. Lightweight aluminum construction with collapsible legs. A level in the head rather than on the leg collar is the better place for it: it reads the plate the instrument actually sits on
Material
Aluminum construction, stated. No wall thickness, no alloy and no load capacity appears — and the other tripod on this shelf publishes a 6.6 lb load
Measuring mode
An integrated level on the tilting head. On a self-leveling laser the tripod need only land within the pendulum range; on a manual laser the head level is the reference the whole job depends on
Supplied
A carrying pouch, stated, plus non-skid feet. At 1361 g (48 oz) the parcel is roughly four times the weight of the other tripod on this shelf, which is what six feet of aluminum leg costs
Also stated
Class II laser, stated — which belongs to the lasers it carries rather than to the tripod, and is the kind of line that drifts across a listing from the product beside it. No elevating column is published

Seventy-two inches, the tallest on this shelf
A level integrated into the tilting head, not the collar
No minimum working height published anywhere
Best for: Ceiling grids, soffits and high layout, where six feet of reach is the requirement
The only tripod here that says how low it goes and how much it will carry — seventeen inches and six and a half pounds.
Stated dimension or range
17 in to 53 in over four different reach lengths, stated. Seventeen inches is the only MINIMUM WORKING HEIGHT published on this shelf — this shelf's buying tip says most laser work happens between 60 cm (23.6 in) and 150 cm (59.1 in), about 23.6 to 59 inches, and this shelf's introduction says the minimum matters as much as the maximum because a tripod that will not go low enough is useless for floor work. This covers the whole band and goes below it
Reference and mounting
A universal 1/4"-20 threaded screw, stated compatible with self-leveling laser levels, cross-line lasers, rangefinders, cameras and projectors. This shelf's introduction says the thread decides compatibility: 1/4 inch suits compact line lasers and camera heads, and 5/8 inch is the construction standard this tripod is not
Body and fittings
A 3-way pan head giving 360° horizontal rotation and vertical movement, with an adjustable 90° sideways tilt — stated. Four discrete extension lengths rather than a continuous column: this shelf's introduction asks whether an elevating column allows fine adjustment without resetting the legs, and four fixed steps is not that
Also stated
A load capacity of 6.6 pounds. It is the ONLY load figure on this shelf, and on a tripod whose entire job is to hold an instrument still it is the figure that says which instruments it holds — a compact cross-line laser is well under a pound, a rotary laser can be four
Measuring mode
A built-in bubble level, stated to let the tripod itself be checked and adjusted. On a self-leveling laser the tripod need only be within the pendulum range; on a manual laser the tripod's own level is the whole reference
Material
Aluminum alloy and PP, stated, with a triangular design stated to reduce vibration, and non-skid feet
Supplied
A carrying pouch, stated, with a minimum length of 17 inches folded — so the folded length and the minimum working height are the same figure, which is what four telescoping sections on a short tripod gives you

Seventeen inches minimum, the only one published here
A stated 6.6 lb load capacity, the only load figure here
Four discrete lengths, not a continuous elevating column
Best for: Floor and skirting work, where a tripod that will not go low is no tripod at all
Two ounces of chalk at twenty dollars, with neither the color nor the grade published — the two things this shelf says decide everything.
Also stated
NO Color and NO GRADE. This shelf's introduction opens on it: chalk comes in two grades and choosing wrongly is not recoverable — temporary brushes off, permanent survives weather and also survives being wrong on a finished wall. This listing states neither, and the buying tip says the color is what normally tells you
Stated dimension or range
Two bottles of one ounce each, at twenty dollars thirty-seven — about ten dollars nineteen an ounce. The other bottle on this shelf is eight ounces for two dollars ninety-eight, or thirty-seven cents an ounce: this is twenty-seven times the price per ounce of powder
Functions
Intended for use with construction MARKERS and marking pen systems rather than a chalk reel — deep-hole marker pens, an Ox pencil, Pica pencil systems and a Tracer TrueShot chalk marker are all named. That is the real distinction on this shelf: a one-ounce bottle with a narrow neck fills a marker cartridge, where an eight-ounce bottle is sized for a reel
Supplied
Two 1 oz containers, stated as a practical multipack and as a gift-ready set. The fifth of five bullets is the gift suggestion
Material
A formula stated optimized for consistent flow and visibility. No fineness figure, no grain size and no material description appears — and fineness is one of the five things this shelf's introduction compares
Reference and mounting
Recorded under the brand "Generic" with the reference US TAPE - DURAMRK - 76700. US Tape is a real layout-tool maker and DuraMark its chalk line; the Generic brand field is a marketplace artefact rather than the product

Sized for a marker cartridge rather than a reel
Compatible systems named: Ox, Pica of the marking pencils shelf, Tracer TrueShot, deep-hole pens
No color stated at all
Best for: Refilling a deep-hole chalk marker, once the color has been confirmed with the seller
Blue chalk sold as water-resistant and fade-resistant, which is the opposite of what the color convention promises.
Stated dimension or range
Eight ounces, at two dollars ninety-eight — about 37 cents an ounce. The other bottle on this shelf is two ounces for twenty dollars thirty-seven, which is ten dollars nineteen an ounce: the same shelf, the same powder, a factor of twenty-seven
Material
Ultra-fine powdered chalk, stated to dispense smoothly and give an even coating with enhanced color payoff. Fineness is one of the five things this shelf's introduction compares, and it decides how cleanly the line lays: a coarse chalk leaves a fuzzy band, a fine one a crisp edge
Also stated
SEMI-PERMANENT, fade-resistant under direct sunlight and water-resistant, "measuring in at 1 on the permanence scale" — all of that on BLUE chalk. This shelf's buying tip says to use blue indoors as a default and keep red for outdoors, because on most brands the color tells you which grade is in the bottle. This bottle is blue and sold as surviving sun and water
Supplied
A fine-tipped nozzle stated to slot into chalk reel openings, minimizing spills. Klein says it can be used with ALL chalk reels — which on a shelf where one reel maker ties its tool to its own branded chalk is worth having in writing
Functions
Stated high-visibility on drywall, concrete, stone, wood and plastic. Plastic is the unusual one on that list and it goes with the water resistance: a chalk that will not bleed is a chalk that marks a membrane or a pipe
Reference and mounting
The product reference recorded for this listing is T5169GKLE while the title and the description both read CHLK8B. Two codes for one bottle, and CHLK8B is the one that matches the 8-ounce blue product
