These brackets are cut from 12 gauge steel. The brackets are designed for 5/16 x 2 carriage bolts. Everything is designed to work with 2x4 structural components and 1x6 shear bracing. The kayak, SUP or surfboards are held at a 10 degree angle (cut ends of shelves at 10 deg) to keep them secure. For my kayaks, the shelves are 31 inches, but your application may vary. I provided bend reliefs at all bends for alignment and to be able to use a 6 inch vise bender.
