The Securitron Magnalock Corporation CWB Brackets are used on concrete filled or wood door frames. On concrete frames, the bracket anchors to the frame via sheet metal screws and the magnet mounts to the bracket via machine screws. The bracket includes a central splice area and avoids the problem of having to drill a wireway through the concrete. On wood frames, 4” wood screws are employed to penetrate deeply into the header. Separate part numbers are used for the M32, M62 and M82 series Magnalock brackets. The CWB Brackets come in two finishes.
