Would have given this a higher rating, but the thing isn't exactly 90 degrees. You need a capability to flex just slightly beyond 90 degrees then back to 90 to lock it. Had to make a number of modifications on my wood project to allow for this extra flex. The wood was perfect 90 degree, this metal bracket is not unfortunately. Otherwise it seems like a good product.
