- The L-support can be used for heavy-duty storage, and works in places where limited space is critical.

- Great for garages, offices, warehouses, maintenance storage, and residential storage.


For better results, the L-support should be mounted directly to a wall stud.

1) Before drilling the holes, verify that the L-support is vertically level.
2) Use a #10 x 2 in (50.8 mm) screw to attach the bracket to the wall stud and tighten until each bracket is secure.
3) Center the shelf on the brackets. Use a #8 screw for the farthest holes on each bracket.
4) Make sure the shelf folds properly. Make adjustments to the L-support if necessary.
5) To secure the L-support, use #10 x 2 in (50.8 mm) screws through the second top mounting hole and through one of two bottom mounting holes.
6) To secure the L-support to the shelf, use #8 screws through the second rear mounting hole and through one of two front-mount holes.

The bracket is made with a durable zinc-coated steel construction and has a spring-loaded release lever.
