Things to Consider When Replacing a Lock
Lock Ordering Tips
Our high security locks come in commercial and residential applications. The main difference is the lock backset. On a residential door or a commercial interior door the standard backset is 2 3/8″, which means the distance from the door edge to the center of the lock hole is 2 3/8″. On a commercial exterior door (usually metal) the standard backset is 2 3/4″. Either way there are only two standard backsets: 2 3/8″ and 2 3/4″
Medeco High Security Locks at Budget Prices:
Single Cylinder Deadbolt
A single cylinder deadbolt requires a key on the outside to lock and unlock the door, and it uses a thumbturn on the inside to lock or unlock on the door. This kind of lock should not be used when there is glass on or near the door.
Double Cylinder Deadbolt
This lock requires a key to lock or unlock both on the inside or outside of the door. This lock should be used when there is glass on or near the door.
Captive Double Cylinder Deadbolt
A captive key attached to the thumb turn puts this lock above the rest. This lock combines the best features of the double and single cylinder deadbolt. When at home you can leave the thumb turn in the lock for ease of use on high traffic doors. While traveling or away remove the key/thumb turn and take it with you. Remember, on all Medeco deadbolts there are no exposed screws.
