Adding a properly sized rivet is the strongest, fastest, and simplest way to install a compatible accessory onto your kayak. This rivet tool comes with 4 interchangeable bits for using your preferred rivet size. The comfort grips ensure that the tool will not slip out while you are tightening your rivets. A wrench, which stores nicely in the handle, easily changes out the bit size wherever you are. It also weighs less than a pound, so you can take it with you anywhere it's needed. Instructions and tips for use are included. Rivets are sold separately. YakGear recommends using a YakGear Tri-Grip Rivet Kit when customizing your kayak.
