I made these brackets to fix a Cyberpower CPS1500AVR battery backup device I purchased used. The L bracket / hooks that hold the front faceplate on were broken. Since straight gluing them would not be strong enough I created these small brackets that fit inside the injection molded inset to reinforce the broken joint. While I chose to super glue to attach them, I did put very small starter holes for self taping M2 screws if you can get a screw gun in at that angle. Since the plastic is ABS before gluing remember to light dab the surface with Acetone. This will soften the plastic slightly to allow the glue to stick better.
