The BAK Revolver X2 is a hard, aluminum roll-up truck bed cover that offers exceptional strength, security, and style. It features exclusive automatic rotational locking rails that secure the cover the entire length of the bed on each side, providing maximum security for your truck bed contents. The cover can be easily operated with one hand, allowing for full access to the truck bed without blocking the rear window. This cover is designed to offer unrivaled strength, security, and style. The Revolver X2 comes equipped with 3/4” Patented Rotational Locking Rails that lock the cover securely the entire length of the truck bed when latched. The 3/4” locking rail or “tooth” rotates into composite locking blocks inserted into each aluminum slat. The cover secures automatically when the spring loaded locking levers are engaged as the roll top is closed. Now the locking rail and blocks are 2X larger, providing extreme security, easier installation and superior off-highway performance. Heavy-duty locking levers are now 3X thicker with reinforced gussets for added strength and are engineered to lock with no adjustment necessary.
