Lockup.

Secure your Kool Rack system to your truck. For use with the Kool Rack bike rack only.

The Kool Rack Lock Kit consists of a round barrel-type lock that replaces the red rubber release button for the hydraulic width adjuster. It uses a cylindrical key similar to that of a U-lock. When in the locked position the Kool rack can only extend. When in the unlocked position, the rack can both extend and be retracted.
