Product details
B511 is formed from 10 mm aluminium alloy bar, weighs 55 g and is listed at 24 kN with a 19 mm gate opening. The product photo and the dimension drawing both show a threaded locking sleeve on the gate.
A light locker in this weight class is typically used to attach a belay device or personal anchor, to clip a chalk bag, pack or tool to a harness, or as a locking piece on a trad or alpine rack. The 19 mm opening accommodates a rope or sling comfortably but is not intended for crowding several large items into one connector.
B511 has a wire-gate partner, B515WR, with the same 24 kN rating and 10 mm bar, which allows a brand to pair a light locker with matching quickdraw carabiners. When requesting a quotation, ask for the current drawing to confirm the locking type, and state the certification your market requires, the sleeve and body colours and the marking. Power Honour works to customer drawings as well as catalogue specifications, so B511 can be supplied as listed, under your brand or in modified form.
