What’s a Finish Plate?

A trim plate protects and hides the inner workings of a mortise lock on entry doors. It is typically made of hardened steel or stainless steel and is attached to the sub-plate with set screws. Without the trim plate, the lock becomes vulnerable to thieves and harmful elements. Mortise locks are becoming more popular in residential settings due to their aesthetic appeal.

A trim plate is a method of securing the inner workings of a mortise lock on the inside of an entry door. The plate serves both to hide and to protect the screws and moving parts of the lock from outside elements and potential thieves. The trim plate for latch systems is typically made from hardened steel or stainless steel. An aesthetic technique is often applied to the finishing plate, which makes it functional in residential entrance doors without giving it an industrial look.

Without the finish plate applied, the operation of the mortise lock system becomes vulnerable to harmful elements. They also become susceptible to would-be thieves or thieves. The components would otherwise be visible, allowing thieves to be able to manipulate the lock’s components to gain access.

A mortise lock is a locking system housed in a casing that is inserted directly into the mortise that has been cut or drilled into the front edge of the door. It is placed directly in front of the zipper side. Since the mortise lock is contained inside the casing and then applied to the door as a whole, the operation which allows the lock to function becomes vulnerable without the application of finishing plates, which serve to hide and cover the dowels to the operation as well as completing the installation by forming the armored casing for opening the door.

The trim plates are attached to the sub-plate via the use of set screws or cap screws. The screws are machined to tighten into the hidden side of the trim plate so that the trim plate is not accessible from outside the door. The steel that trim plates are typically made of is formed to prevent the plate from bending or twisting, so that no one will be able to access the mortise lock inside.

Finishing plates are a key deterrent to people who would otherwise attempt to enter the premises through manipulation of the lock mechanism. Typically, the trim plate is also shaped in a way that makes it even stronger due to its shape. Typically, extreme force is required to negate the trim plate to gain access through any means other than the key.

Mortise locks have become more popular in residential applications. Their popularity has grown as they have become more appropriate for residential settings as the finish slabs allow for more aesthetic methods of manufacturing. However, they have been used for a long time in industrial and commercial settings.
