1/2" Pipe Clamp Mounting Insert For 9 Inch Rubbermaid Dual Support Brackets

This is a insert that mounts in a 9 inch dual Rubbermaid shelf bracket that holds 4- 1/2" wood working pipe clamps. You need a set for every 4 clamps. There are holes for 2 screws from the bottom to secure it to the bracket. The tolerance on the bracket is about .5 mm so I designed it to fit the narrowest bracket they had at Home Depot and it is a little loose in the wider ones they had.
Can be 3d printed or made from wood.
