So innovatively simple it"s no surprise Inno Racks engineered it, the Inno RT101 Truck Rack Stays are designed for use with any standard pickup truck beds. Use in combination with a pair of Inno Racks crossbars (to determine the best crossbar length, simply measure all the way across your specific pickup truck bed). Attach any gear carriers from Inno Racks, or other car rack manufacturers directly to the Inno crossbars. The Inno Truck Stay and Cross bar system is a superb way to transport all types of gear above the pickup truck bed but still remain at a very convenient height for loading and unloading. Also a more aerodynamic and fuel efficient alternative to traditional truck rack systems with towers that transport gear and equipment above the truck cab height. Inno truck racks more affordable than virtually all other competitors" pickup truck bed truck rack systems. Convenient to adjust the front Stays & crossbar and rear Stays and crossbar any distance from each other for whatever you need to transport. Still frees up truck bed for carrying gear and cargo below the truck rack. Quick and easy to mount, no drilling required.
