Aluminum Backer Plates

1 review Write a Review


Our aluminum backer plates are recommended if you are going to install a downrigger or have thin walls on your boat. The added support from a backer plate is recommended for our 6", 12", 18", and 24" mounting tracks. Our longer tracks usually do not require a backer plate because they spread the strength out over the length of the track.

If you wish to use a backer plate with a piece of mounting track 36 inches or longer, we recommend that you use a 3-inch plate.

Frequently Asked Questions:

Q. How many backer plates/what size do I need?

A. If you are installing a 6", 12", 18", 24" or 36" track, you need to order just one backing plate in the corresponding size. If you are installing anything over 36" and wish to use a backing plate as well, you must order the 3" backing plate - (Part: #3-BP). The other size backing plates will not line up properly with the mounting holes on your tracks.
