Robson SC20 Fitting Suspension Puzzle clip fits 20mm hole

Robson SC20 Fitting Suspension puzzle clip fits 20mm hole.

Design to suspend any light fitting that has a 20mm diameter suspension hole on the top of the fitting body such as a fluorescent batten fitting that has 2 or more 20mm entry hole on the back of the spine that could be used for fitting 20mm conduit hooks with locknuts.

By using the "Puzzle" suspension clips by passing the suspension jack chain through the 20mm hole first then passing the chain onto the puzzle suspension and withdrawing the chain back though the hole until the puzzle suspension clips into place in the 20mm fitting hole.

This is a very safe way to suspend a fluorescent batten fitting, if the fitting is accidently raised at one end the suspension clip will not un-hook from the chain which woud happen with a convential open hook
