To Install 1. Need to hole saw 40mm hole into the gate post so the body of the closer is hidden and out of the way.
5mm 40mm Pencil 3,4,5mm 18V punch Level / Laser
If the wall thickness of the post is too thin maybe the weld on version is more appropriate.
Kit price includes;
1 x GC118 1 x GC110 2 x GC188
Some Gate installers have welded on a flange to give the Closer more support on the gate, If you do this make sure you mark and take the hinge off, don't weld on the gate heat transfer will harm the piston on the post.
