This is a 2 part bracket for mounting a leg to a table/desktop or flat surface.

The 2 pieces snap together - the base plate attaches to a surface and supported with a couple of screws. Use Kreg 1' inch cabinet screws to attach the leg to the flat surface top or bottom, and #8 1/2 in. flat head screws to attach the plate to the surface top or bottom.

The "base plate" serves as a place holder to help align the columns on the surface top. The second piece (the adapter) goes on the end of a "column" or "leg" and snaps into the base plate.

** included sketch from fusion - current dimension of leg is 58 mm
