The concept with the Wave backrest installation is this:
- The crossbar end caps are removed. - The backrest tubes insert into the crossbars to a plastic stop. - A hole is drilled through the hull deck through the crossbar sleeve, crossbar and into the backrest tube. - The backrest is removed and the holes in the backrest tube are enlarged slightly. - Re-insert the backrest. - Depending on needs, either a flat head screw or quick release pin is inserted into the hole (diameter of the hole is different). The screw is flush with the deck and requires a driver to install and remove.
This is a tight fit as the fastener passes through the hull and crossbar but a loose fit in the backrest tube to allow some flexibility there without shearing the pin / screw.
So the pins / screws are simply there to hold the backrest into the crossbar. As you lean on the backrest the tube in the crossbar presses up against the crossbar. Plenty secure.
