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 four 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.
