Part # BP - BP / Aluminum Backer Plates
Recommended if you are going to use down-riggers or have thin walls on our boat.
This added support is recommended for the 6 inch, 12 inch, 18 inch, and 24-inch mounting tracks.
The longer tracks spread the strength out and a backing plate is usually not necessary.
If you wish to use backing plates with tracks 36 inches and longer we recommend that you use the 3-inch ones.
Q. How many and what size backing plates 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.
