Great Day's Center-Lok Overhead Gun Rack for most full-size Crew Cab pickup trucks employs a patented "Opposing Forces" installation system. This incredible system locks the gun rack solidly into place in a couple of minutes. No drilling, no screws or bolts required! No alterations to the roof that void a manufacturer's warranty. The Center-Lok Gun Rack fits most full-size Crew Cab pickups with center doorposts. The Center-Lok Gun Rack positions your gun(s) snugly against the headliner of the truck, totally out of sight of passersby, and still provides abundant headroom for the driver and passengers. The gun(s) are held securely in cushioned, moldable gun clips with Velcro straps and can adjust independently to fit different sizes. The Center-Lok is framed in aircraft aluminum and finished in a handsome, durable coat of powder-coat enamel. Expands from 48" to 54". Weighs only 9 lbs. Lifetime warranty.
