More About Marks USA

Mortise locksets require a pocket like cut-out in the door in order to install their mechanisms. Such locks may have a more time consuming preparation and installation process, but the results are definitely worth it.

Mortise locks are designed specifically for heavy duty applications. They are very strong and durable locks that will withstand the rigors of commercial use and abuse for many years. They will also provide uncompromised  security for your building and ensure your safety at all times.

There are also mortise locks that incorporate a deadbolt as part of the set which adds a measure of security to your door without necessitating another lock. Most mortise locks operate with the use of knobs or levers and are available in many different styles, finishes and functions. There is also the style choice of  an escutcheon or a rose trim.

Qualified Hardware carries an extensive variety of mortise locks, with many options and features, to accommodate your needs. Our team of knowledgeable representatives will be glad to assist you in finding the lockset that is perfect for you.
