Product details
A500 is a rectangular aluminium alloy frame with a 47 mm inner size and 4 mm thickness, rated at a 15 kN minimum breaking load. The product photo shows a stepped frame outline, which distinguishes it from the plain rectangle of the A502 with the same figures.
In harness construction, a frame like the A500 is typically combined with a slotted buckle to make a quick connection on leg loops, chest straps or waist belts, so the user can put the harness on and take it off without rethreading webbing. Because aluminium is light and can be anodised in colours, it is popular on rope access, arborist, rescue and lightweight fall protection harnesses.
Buyers should confirm the webbing width and thickness against the 47 mm opening, and state which mating buckle will be used. Specify anodising colour and marking in the RFQ, and request a drawing for full dimensions. Power Honour can supply the A500 as OEM or private-label hardware and can modify it to a customer drawing.
