worth it for a woodworker
Size: 6FT, Color: Black-20W
It is a nice solid deal. you just rout out a hole large enough for it to set in. It mounts with two screws. I don't have a negative. I'll be getting more for my woodworking. Thank you.

Great product
Size: 6FT, Color: Black-20W
Added two of these behind the couch in a wood ledge between the couch and the wall. A template will make marking the cutout easier. You will need to make one as it does not come with the product.
