Mathews Engage Side Plates are designed to replace the Engage grip in order to give a slimmer profile.

To install the Engage side plates you should first determine where you are going to attach the tape and clean the mounting area and the side plates with the provided alcohol wipe. Then you can simply remove the backing from one side of the tape to attach it to the plate and then remove the backing from the other side to adhere it to the riser.
