The universal header bracket is used to extend a narrow header (often found on aluminum framed glass doors) to allow mounting of the magnetic lock. The bracket is positioned either to extend 1 inch or 1 1/2 inch and also serves to conceal the hookup cable within the hollow interior. It will work with the Securitron 600 or 1200
mag locks. It's color is clear anodized aluminum. We have found this manufacturer to be extremely user friendly !
