Product details
The A502 is an aluminium alloy quick buckle in the form of a rectangular frame, with an inner opening of 47 mm, a thickness of 4 mm and a minimum breaking load of 15 kN.
Frames like this are commonly used as one half of a two-part harness buckle, working with a slotted plate so a leg or chest strap can be connected and released quickly, and they also serve as simple strap keepers and adjusters. The 47 mm opening leaves room around the webbing, so buyers should confirm the fit with the exact webbing width and thickness they use. Aluminium suits harness makers who want quick buckles that add little weight, for rope access, rescue, arborist and industrial fall protection products.
The A500 has the same inner size, thickness and rating with a different frame shape; compare drawings before choosing. In the RFQ, specify the mating part if one is needed, the anodising colour, and any marking. Power Honour can supply the A502 for OEM or private-label programmes and modify it to a customer drawing.
