L Bracket

I made this bracket to hang wood "tiles" between the floor joists in my basement for mounting LED wafer lights. I ran out of metal brackets and these work great.

55Lx20Wx25H (mm) with an 11mm trough to fit a washer. The corner has a cut-out so you can get your screw started and then slide the bracket over it.

Let me know if this works out for you!
