Wall thickness, and a missing inside dimension
Back extension benches, leg presses, plyo boxes, power bags and power racks.
Steel sections. The vertical leg press names 2 mm tube wall and takes both 1-inch and 2-inch plate posts; the cage names a 50.8 × 50.8 mm reinforced main frame and publishes 454 kg.
Those are the numbers that carry the load, and this brand gives them more often than most.
Inside width and inside depth, on a cage. The listing publishes an occupied volume of 0.501 m³ instead — a single number where three are needed, since a room accepts three dimensions and a bench has to fit between the uprights.
The review page records the substitution rather than accepting it.
Unfilled, 2–11 kg capacity, 1000D Cordura liner
An empty shell sold by its capacity: 2 to 11 kg once filled, with a 1000D Cordura inner bag, YKK zips and a waterproof outer.
Best for: Somebody who has sand and wants a shell that will survive it
Carbon steel, folding, 113 kg
A folding carbon-steel roman chair rated to 113 kg — the lowest on this shelf — with the adjustment described but never quantified.
Best for: A room where the bench has to disappear between sessions
Plate-loaded, 1 in and 2 in posts, 249.48 kg, 2 mm carbon steel
The only dedicated leg press here: plate-loaded on interchangeable 1-inch and 2-inch posts, rated to 249.48 kg, on 2 mm carbon-steel tube.
Best for: Loading the legs past what any stack on this shelf reaches
458 mm, steel trapezoid, silicone top, rubber feet
The only steel box in this family — a welded trapezoid at 458 mm with a textured silicone top and four rubber feet, rather than a wooden cube.
Best for: A single working height where the base needs to be wider than the top
50.8 × 50.8 mm frame, 454 kg, 0.501 m³
A genuine four-post cage rather than a pair of stands, with a published 50.8 mm square frame, a 454 kg rating, eleven J-hook positions and seven safety positions — and a published volume.
Best for: A room with the ceiling for a cage and a bench that has to go inside it
