The Grip Holders feature removable black foam inserts. Removing these inserts increases the grip opening size so larger rod handles can be loaded. Replacing the inserts creates a grip opening perfect for accommodating smaller lightweight rods. This allows you to carry any combination of sizes and types of rods and reels with your RodLoft PRO. In addition, each of the grip holder’s feature special cutouts that secure rod tips when carrying your rods broken down.
