Roller Shutter Contacts

These are heavy-duty contacts for use on roller shutters on shop fronts etc. Below we see a half closed shutter. The magnet is concealed behind the shutter to reduce the risk of tampering. The contact is secured to the ground by self tapping screws and the cable is passed through a pre-drilled hole in the wall.

As you can imagine fitting these contacts is not an easy task so care should be taken when doing so.

Make sure the shutter can retract to its full height when the magnet is bolted on.
