For curved roof supports and you desire a bottom that small items can't fall through.
This light weight cargo rack has a solid bottom floor. The floor is made of high grade aluminum and is supported by two aluminum crossbars that allow the flex required to match the curvature of most vehicle roof top support systems. This aluminum floor is sealed around the bottom tubing by strong metal epoxy and silicone, bonding the floor together with the tubing, sealing any fluids from escaping; when you order, you"ll have an option to have a drain hole placed for draining any liquids. The side rail tubing are made of lite weight metals that are strong and durable so there are no worries of bending or breaking. The vertical supports are made of strong high quality aluminum.
