It's more complicated than cylindrical bore locks, and requires a wider door to accommodate it. You'll see them more on commercial doors than on residential ones, however, they can be installed on some internal and external doors. A mortise lock consists of several levers and a bolt, that retracts into deadbolt locks that are inserted into the frame of the door. It is a safer option than a rim lock and can be used in combination with other locks, such as a five-lever mortice lock or night latch. When measuring a mortice you need to consider various dimensions, including the depth, backset, and the handle follower. The case depth is the distance from the edge of the face to the middle of the key hole, and the backset is the size of the spindle, or handle which operates the bolt. The square hole that is located in the lock body is called the follower. It is usually 8x8mm however you can select an alternative size that is suitable for the door handle you are using. You'll also need to know the BS standard the lock must meet. There are different levels of security that are available.

The majority of insurance companies will insist that you install these locks on your home. If you're thinking about installing a mortice lock on your door, be sure to look into the range of escutcheon trim plates as well as other accessories that are available, since they can improve its appearance and provide extra security features. Consider cylinders that can add more flexibility and function to your door locks. Certain cylinders, such as provide anti-drilling security which protects the lock from attack by hammers or crowbars. Euro Profile Cylinder Locks uPVC door Cylinder locks are widely used and can be combined with deadlocks or rim locks to offer greater levels of security. They are simple to install and operate with keys. They can be keyed alike so that all of your door locks will operate with the same key. The key fits into the cylinder and shifts pins of various lengths to stop the lock from opening without the right key. A standard cylinder lock consists of five pins. However, there is window fitters romford -pin version available to provide additional security. There are also anti-snap euro locks with an sacrificial stripe that is cut into the cylinder to guard against attack techniques like lock snapping. Euro cylinder locks can be useful and secure, but they do have a flaw that criminals could exploit to gain access to homes. This weakness is the cam located in the middle of the cylinder that connects both sides of the plug. If the cylinder is damaged, the connecting pieces can be dislodged and disconnected from the rest of the lock, allowing the plug to be turned to unlock the door. To prevent this from happening it is crucial to ensure that the cylinder will not protrude from either end of the lock (if too short) or get swallowed by the door. To measure for a new cylinder, remove the old one from the door. Take two measurements. First, measure from the end of the barrel to the middle of the screw hole on both sides. This is the external size to center measurement (A). To measure for the internal side, put the key in the same position and turn it to the right or left. Then, use a ruler or tape to determine the distance from the centre of the keyhole to the outer edge of the lock furniture or handle (this is your internal size to centre measurement, also known as B). You can measure the door lock by using a ruler or tape, but this method will be less accurate due to the fact that the cylinder could move when you turn it. RIM Locks A rim lock set is a lock mechanism that is usually fitted to the surface a door. This type of lock is commonly that is found in homes of the past. It is full of charm and character and is a great choice for those who want to give their house an old-fashioned look. It's also a great choice for doors that are too small to accommodate mortice locks. It can be used with handles or knobs for doors. James Carpenter patented his first rim lock lock in 1830 although the design of the latch was based on an old-fashioned lock that his father had improved upon. It has an omnidirectional keyway that can be locked by a single or a double turn of the knob. Its cylindrical cam is fitted with a variety of levers that extend from the door and are inserted into holes in the door jamb when the lock is turned on. In contrast to other locks that work by rotating pin tumblers, the rim lock has a different locking mechanism and utilizes a shear point to isolate the snib from the bolt. This is how it differs from other cylinder locks, and is the reason why it doesn't have a keyhole as do most modern locks. Rimlocks are available that does not use a shearpoint, however they are less secure because you can easily force the latch open by hand. Installing the rimlock requires you to first mark and drill a hole into your door to accommodate the spindle, then screw the lock body into place. Once it's securely mounted it's time to attach the keeper and escutcheon plate. The escutcheon plate protects the snib and defines the keyway of the lock. The plates are available in different styles, so you can easily find one that fits your door and home. Rim locks are no longer as popular as they were in the past, but they do still provide a good level of security for indoor doors as well as for sheds with thinner doors that aren't compatible with mortice or deadbolt locks. They're also ideal for adding privacy and security to bathroom doors since they can lock from both sides.
