Used to attach Rakks extruded aluminum shelves to a Rakks Style shelf support bracket so that they cannot be easily removed. Hold down clips should also be used when the end of the shelf does not extend very much beyond the bracket and might slide off. The hold down clip is secured to the shelf with a setscrew from the bottom and secured to the bracket with a setscrew from the side. When using shelf hold down clips, it is not necessary to order retaining pins. Finish: Clear anodized aluminum.
