The HD Awning Bracket was designed for the heaviest and largest awnings, and specifically engineered for the Alu-Cab Shadow Awning. This is a MUST HAVE product if you are planning to mount an awning longer than 60” on a Jeep Gladiator as it allows the awning to go over the roof. The HD Awning Bracket attaches directly to the load bars which DOES NOT ALLOW the rear load bar to slide.
