Installation Guide

Special installation requirements for fibreglass struts

Fibreglass will not support support screws drilled and tapped into it. The sheering force of a line cut is too great; therefore, the screws that hold the holding block will pull out.

We recommend when installing the holding block onto fibreglass that a metal plate, approximately 1/4" thick, be embedded into the fibreglass. The plate can be stainless steel or aluminium.

1) The installation is achieved by first measuring to determine the depth required, then routing away the glass to receieve the plate. Using stainless steel flat head screws and epoxy, mount the plate inot the routed area.

2) Drill and tap into the plate and mount the holding block.

3) Bond the plate and holding block by screwing a small zinc anode onto the plate.
