The backing plate provides four threaded holes used to secure the bracket to the mast track. Depending on the height of your sail track entrance slot, the backing plate may not want to enter the slot.

To install the new backing plate it may be necessary to either:
a) Increase the height of the mast entrance gate
b) Cut the backing plate in half and insert the two pieces, one at a time or
c) Remove the mast and install the backing plate from the base of the mast.
