garage locks Various options exist when securing your garage door locks. We carry a selection of replacement garage door handles alongside additional bolts & locks for up and over garage doors. We find the most popular 'up and over' garage locks are the Enfield garage bolts. They provide additional security to the standard lock and are suitable for single or double garage doors. A further advantage with the Enfield bolts is they can be keyed alike, so if you have a number of garages you can make your job a little easier when it comes to opening them....
