Aluminum / Vinyl Decking
We do not recommend attaching the Bolt On Kayak / Paddle board Surface Mount
directly
to
Aluminum / Vinyl decking as the Decking material is thin, however supported by 3 vertical members.
Given you choose to mount the Surface (Bolt On) Mount to Aluminum or Vinyl Decking;
it is highly recommended that you install a backer board in the area of the mounting positions.
Option #1
The backer board should be slightly smaller than width between vertical members of decking and at least
6 inches long. The thickness should not extend beyond the height of the decking vertical members.
Option #2
The Backer board should be wider than the width between vertical members of the decking, at least 6
inches long; and have a thickness of ¾ to 1 inch.
When securing the Dock Bolt On Mount; the decking is actually clamped between the Bolt On Mount and
the Backer Board. Use caution as not to over tighten.
