Review on Heavy-Duty Stainless Straight Brackets: Ultimate Mending and Repair Solution for Industrial Hardware by Adan Hudson

Used these on the corners of a new bed to keep the mattress from shifting and they worked great with some washers, nuts and bolts. I even have an extra for another bed. I'm thinking of using some of these on my front doors as an extra security lock that you just stick on the door at night. I can use some in the kitchen to hang dishes. They are universal.
