DescriptionThe OS850 awning bracket is designed with welded gussets to provide additional strength when awnings are mounted to roof bars on vehicles used off road or under extreme conditions. Zinc plated and powder coated for corrosion resistance and designed to mount either upright or inverted, the OS850 awning bracket is 50 mm wide allowing it to fit over both Thule SquareBar and Rhino Heavy Duty in the inverted position, or upright using T-bolts or channel nuts on Thule ProfessionalBar, WingBar and AeroBar or Rhino Heavy Duty. Pre-drilled to accept 8mm bolts, at least 2, but preferably 3 bolts should be used to mount to the roof bar for maximum strength. The outer bolt hole between the gussets must always be used for the gusset to be effective. Three slotted 6mm holes are provided to mount the awning. The 813402 awning bracket is not supplied with hardware. Due to different bar designs, it is recommended to use T-bolts and channel nuts supplied by the roof bar manufacturer. Units are now in stock with additional shipments due mid June. The current awning bracket P/No OS3071 has recently been upgraded from 3mm to 4mm construction however it is considered lighter duty and designated for highway use.
