A small simple and practical hook. The lock avoids the chain sliding out of the hook when there is no tension in the rope.
The 7,9 mm (5/16") opening of the grab hook will accept either 6 mm (1/4") ou 7,9 mm (5/16") chain.
Three 8 mm chain links are installed at the end to easily connect to a rope with a 13 mm diameter or less or to a carabiner.
Attach it to the rope using a bowline knot which can easily be untied after use and which will maintain up to 70% of the rope’s capacity.
Its working load limit (WLL) is 20 kN (2039 kg - 4496 lb).
