Does your door lock employ two or three cylindrical bolts and maybe another pair of bolts top and bottom? Do youwindthese bolts out andwindthem back in again? You may have a Mul-T-Lock door. If you look around the handle fittings you’ll usually find the name there. The good news is that if you do have such a door, you have a very good door and lock system—pretty strong and secure. Your letterbox, for example, is probably a long way from the lock and is protected by a nice strong cowl. |
