Under The Hood: UNION’s New Heavy Duty Mortice Lockcase


UNION recently launched a range of all-new heavy duty modular euro-profile 72mm lockcases which delivers an unrivalled level of performance while meeting current security standards around fire and equality of access.

The new lockcase has been designed to cover a wide range of typical needs in specifications and is available in six variants; sashlock, deadlock, mortice latch, deadlocking nightlatch, bathroom lock and an emergency escape lock. The range can also be specified with either a square or radius forend, and all come in a wide choice of finishes, pitching them as a high quality lock solution for door manufacturers.

 The lockcases have been subject to intensive testing to ensure they can deliver a high level of durability. Headlining this is a test result of over 3.5 million cycles, an impressive figure far in excess of the demands laid down by BS EN 12209 and appreciably above the performance of competing products.

“We’ve gone to a lot of trouble to produce a lockcase that answers common issues specifiers and installers face,” says Karen Hubbard, Product Manager for Mortice Locks at UNION. “To reach 3.5 million test cycles says a lot about how durable the new lockcase is, but there’s the also the details we’ve built in to this new lockcase to make it really convenient to both specify and install.”

Beyond the numbers the new lockcase contains a number of features that will appeal to specifiers and installers alike. First, the lockcase incorporates heavy duty springing to support handles up to 930g in weight and a follower set at one degree away from vertical. Combined, these allow specifiers the freedom to be more design-lead in projects, while also combatting against drooping levers – the bane of many projects particularly with doors in medium – heavy usage areas.

As the entire range meets Grade 3 category of use the new lockcase makes a strong case for use in areas where it could be subjected to heavy use or even abuse.

The lockcases are a universal fit for both door hands via a simple way to rotate the latch without resorting to hunting for tools; just move a release pin located in the lockcase up and pull the latch out, then turn it round. For anyone wanting to get away from the time (and risks) involved in dismantling lockcases to do the same thing will find just feature alone a boon but it bring other benefits too.

There’s no need for a specifier to analyse and check each door in a project to accurately state what product variant is needed where, while an Architectural Ironmonger can better manage stock – and an installer will find locating the right lockcase for a job quick and easy.

Being able to secure a door, or open it to escape, quickly by anyone has become increasingly important when looking at lockcases. The range has been designed with a single-throw, 20mm deadbolt that is easy to use – so a user should not be confused with double turns on to lock and unlock, or wondering if the door has been properly secured.   

On the subject of speed and efficiency, another useful feature of the new lockcase is the adjustable strike plate, which allows the installer to make a door seal effectively in the doorframe and, therefore, potentially eliminate irritating rattles. This helps make the installation have a professional appearance and a quality feel in use – and as the lockcases are CE marked and certified for use in timber and metal fire doors, this helps an installer or property owner alike ensure a door will pass a fire inspection. 

The new  lockcase range is already proving a hit with specifiers and installers alike. It’s an ideal choice for doors in first-fit and retro-fit projects, and with a 15-year guarantee, is a durable, heavy duty solution that will stand the test of time.
