Mortise Locksets

A mortise lock is a lock that requires a “pocket” – the “mortise” – to be cut into the edge of the door or piece of furniture into which the lock is to be fitted. In most parts of the world, mortise locks are found on older buildings constructed before the advent of bored cylindrical locks, but they have recently become more common in commercial and upmarket residential construction in the U.S. Interestingly, mortise locks are widely used in domestic properties of all ages across Europe.

Mortise locks have been used as part of door hardware systems in America since the second quarter of the 18th century; in these early forms, the lock mechanism was combined with a pull to open the unlocked door, until the pulls were replaced by knobs. Up until the mid-19th century, mortise locks were only used in the most formal rooms in the most expensive homes, with other rooms utilizing such contraptions as box locks or rim locks in which, unlike with mortise locks, the latch itself was housed in a self-contained unit affixed to the outside of the door.

Park Avenue Locks carries a complete inventory of premium mortise locksets from noted manufacturers in the industry such as Schlage, Cal-Royal, Yale and Emtek, in an almost infinite variety of styles, applications and finishes.

One of the best-selling models in our entire lineup, the Schlage L9010 mortise passage latch, features a latchbolt retracted by the knob/lever from either side at all times, making the inside knob/lever always free for immediate egress. Further, the L Series from Schlage not only exceeds ANSI/BHMA Security Grade 1 and Operational Grade 1 standards, it also serves as the foundation for the Schlage L wired electrified, LE<./i> wireless electronic and multi-point mortise lock portfolios.

Meanwhile, our Cal-Royal offerings in the mortise lockset category include noteworthy collections such as the NM8050/8453/8465/8473/8070/8080/8495 and a plethora of others, while the featured Emtek offerings encompass entry mortise locksets in the Brisbane, Mormont, Artemis, Harrison, Manhattan, Charleston and Memphis series.

This is just scratching the surface of what awaits in Park Avenue Locks’ impressive mortise lockset inventory.

What You Should Know About Installation

The installation of one of these locks can be undertaken by the average homeowner with a working knowledge of basic woodworking tools and methods, though many installation specialists suggest using a mortising jig which makes precise cutting of the pocket a simple operation. Still, the subsequent installation of the external trim can still prove problematic should the installer be inexperienced.

A mortise-type lock typically accepts a wide range of other manufacturers’ cylinders and accessories, allowing architectural conformity with lock hardware already onsite.
