Made of 1/2 in (12.7 mm) diameter heat-treated steel stock, this industrial-sized, high-strength carabiner features a wide gate opening, useful for attaching to rungs on aerial ladders, buckets and industrial rescue or rope access anchor points that are too big for most rescue carabiners. The nut locks on the gate to prevent jamming. The gate opening is a full 1.53 in (39 mm).

Every carabiner is proof loaded.
