The thick steel wire loop is shaped so that with the strap folded through it, the loop has a very high resistance to opening under load.
Hole size is 4mm. Pan head screws are best for fixing to the frame. These can hang directly onto suitable hooks on the wall. Or, when set at an appropriate angle, use with cord or wire.
Safe working load, based on our judgement and experience: 17kg.
