prota Plastic folding rules, 2 m (7 ft), set of five review
Five 2 m (7 ft) plastic rules in one pack: a PC body on ABS connectors, ten segments folding to 230 mm (9.06 in), in white with a black scale. The set to buy when rules keep disappearing.
What the figures leave us with Bought by the pack, not by the specification. The right choice when the failure mode is losing them, not wearing them out.
A five-pack is a different kind of purchase from a tool.
What the manufacturer publishes
Five white folding rules, 2 m (7 ft) each, in ten segments folding to 230 mm (9.06 in). A PC plastic scale body on high-strength ABS connectors. A white background with black graduations, with centimeter figures described as clearly legible.
What the pack is actually solving
Folding rules are lost, not broken. They end up in a different bag, on a different site, in the pocket of the jacket you did not wear. Buying five at the price of one good one means the answer to “where is the rule” stops being a search.
What you are giving up
No EC accuracy class is stated. The three wooden rules in this hub all state class III; this pack states nothing, so there is no published tolerance on the graduations at all. Plastic joints also wear faster than brass ones under repeated folding. Neither matters much for rough measuring, and both matter if the rule is your reference.
Availability
Catalogued and unsold: the American Amazon shop lists the reference with nobody behind it.

Compromises

What gets asked here
Is plastic better than beech?
It is different. Plastic ignores damp, which ruins a wooden rule left outside, and it is lighter. Beech is stiffer and its brass-jointed versions hold a straight unsupported line longer. For a rule that lives in a damp shed, plastic wins.
What accuracy class does prota state?
None. There is no EC class marking mentioned in this listing, where the Stanley, Meister and PRESCH rules all state class III. That is the specification this pack does not give you.
How small does it fold?
The maker states 230 mm (9.06 in) folded, across ten segments.

3 m (10 ft) beech · 15 segments · EC class III · extra-large tens
Three meters of beech in fifteen segments, marked to EC class III, with extra-large tens figures for reading at arm's length and a double scale along both edges.
Best for: The default building-site rule: three meters, legible, and cheap enough to replace without thinking.
3 m (10 ft) beech · EC class III · integrated angle scale
A 3 m (10 ft) beech rule with an angle scale printed into the joints, so it marks and sets angles as well as lengths — the one function a plain rule cannot do at all.
Best for: Roofing, joinery and anything where the question is what angle, not just how long.
The most expensive rule here, and the only one specified as a marking tool: glass-fiber reinforced polyamide joints, a scribing function with a continuous straight edge when unfolded, PEFC beech and a quick-read scale.
Best for: Someone who marks against their rule all day and wants one that stays straight while doing it.
