What Do I Need to Know About Lock and Mortise Sizes?

Home security is an essential part of our safety. We should know about the different locks and dimensions that ideally work for our doors and homes to protect ourselves. This blog looks at two popular locks and their respective sizes.

What’s a Mortise Lock?

A mortise lock involves a metal case with the functioning part of the lock in a mortise shape in the design of the door. The lock has a latch bolt to keep the door locked for interior doors in continual use. Mortise locks can either be horizontal or vertical.

Size Of Mortise Locks

The mortise lock size is the complete length of the body from the external front to the rear edge. The typical dimensions of these locks are 65, 75 and 100 mm. The exact width of the body is generally up to 35 mm.

What’s a Cylinder Lock?

Cylinder locks are the most popular door locks, especially in Europe. These locks are a type of pin tumbler. They have pins of various lengths that push against the jagged edges of a key to distinguish the correct pattern to unlock the door.

Pin tumbler locks commonly include a cylindrical design, and is a specific cylinder lock with a cross-section design. The cylinder barrel is convenient to fix, and substitutes let you alter the companionable key to improve security. You have to slacken a screw, remove the cylinder, and change it with a similarly sized replacement.

Some Cylinder locks include five pins, while others have six. The former costs a little less but provides less security than six-pin ones. People also call Cylinder locks OR Euro lock barrels.

Sizes of Cylinder Locks

Euro locks are present in different sizes to accommodate other doors. The lock length you require can rely on the width of the door, so start by calculating that.

Generally, larger Euro lock sizes extend from 60 to 120 mm. The central cam is present exactly midway along with the drum. Meanwhile, standard half Euro cylinders can be 40 to 50 mm long. You can measure these lengths as whole numbers or in halves. For instance, a 40 x 40 mm lock can be considered 80 mm.

uPVC doors prove to be an exemption. Thanks to the standard sizes of these doors, companionable locks – usually 70 to 120 mm long – have flexible lock cylinder sizes. For instance, an 85 mm uPVC lock can be 45 mm long and 40 mm long.

 

Euro Lock Cylinder Dimensions

You can alter the main cylinder of a Euro lock relatively quickly to accommodate a new pair of keys. Still, to accomplish that, you have to measure the dimensions of the current Euro lock cylinder. You can calculate that while the Euro lock is either still inside the door or once you remove it.

Calculate from the middle of the screw to the flanks of the base of the handle backplate. The backplate is the plate on the outer side of the door. Estimate the measurements to 5 mm on either side. You can also calculate the cylinder drum when you detach the lock from your door—calculate from either end to the center screw, plus the primary cam ring.

 

In Conclusion

For our own safety and the upgrades to be done, it’s important to know what you need by knowing the size and type. If not please consult a professional where it makes this whole experience much straight forward.
