These sections are for 6-10mm glazing and were primarily designed for steel or aluminium hulls. They are now used extensively on GRP boats.
The main advantages of a clamping section are:
- Speed of fitting
- No screw heads visible externally giving a modern and sleek appearance
- No need to drill holes in the structure ensuring there is no unnecessary corrosion or leakage
