Cross Bar Kits consist of one cross bars and two mounting towers. The 1-1/8" diameter by 3/16" wall thickness, stainless steel cross bars are compatible with Yakima, Thule, and most other brands of roof mounted accessories designed to attach to round tubes.
Each Cross Bar supports 75 lbs. The 4" height is a more compact design, the 7" height allows mounting kayaks upside down as well as mounting lights or other gear below the cross bar while still carrying gear on top.
