This Metal Ridge Clamp Pack from Samac is perfect for roofing projects. The ridge fixings are secured into the ridge and hip unions by driving the countersunk screw, along with the washers and clamp, through the hole in the top of the ridge and hip union and into the batten below.
The screws are then tightened down so that the clamp presses down on the ridge/hip tile securing it in place, making it weatherproof and maintenance free.
