I've done a lot of 3 inch thick shelves whre I could fabricate a cleat
screwed into studs and slip the shelf over the cleat. Now the shelf is
a 7/8 inch thick 5 foot slab of Sapele.. maybe 5 inches deep. Can I
make a cleat or does somebody make one I can use for this
application?? I would think I need metal here. Thanks much
