ASSA ABLOY consolidate concealed door closer offering


ASSA ABLOY, the world’s largest security door solutions provider, supplies concealed cam motion door closers in two model sizes, designed to suit a variety of applications and aid the specification process.

The DC840 and the larger DC860 concealed cam motion door closers accommodate controlled closing and easy opening of single action doors. Thanks to the cam motion function, the ASSA ABLOY door closers provide security whilst assisting in ease of operation by the young, elderly and those with a disability.

The reduction in the door-opening force required at the start of the cycle, the most strenuous part, assists building owners and specifiers in meeting the requirements under the Equality Act, specifically BS8300 and Approved Document M.

The streamline design and concealed element of ASSA ABLOY’s door closers help to create a more subtle and attractive finish, ideal for modern office developments or high-end retail locations. 

Plus, this streamline appearance helps reduce the build up of dirt and bacteria, making cleaning easier and creating a more hygienic environment, which is particularly beneficial for healthcare and education applications. It also has the added bonus of being more resistant to wear and tear and physical damage, as the main elements are concealed within the doorset, helping to prolong its life cycle.

The DC840 has the smallest footprint in the ASSA ABLOY range, making it a cost-effective contract solution, suited to the majority of public and commercial projects and a popular product across most specifications. Suitable for doors up to 1100mm and for both right and left hand swing, it is both practical and, thanks to its streamlined appearance when installed, attractive.

The DC860 is a larger version of its predecessor, suitable for heavy-duty applications and doors up to 1250mm, whilst maintaining the functionality and visual appeal of a concealed cam motion closer. Suitable for both right and left door direction, it has a variable closing speed between 0-120º, ensuring security and ease-of-use.

Both the DC840 and DC860 cam motion door closers are CE marked in compliance with EN 1154, which classifies the safety and security of controlled door-closing devices.

Lorna Ardern, Product Manager for ASSA ABLOY Security Solutions, explained:

“Along with the rack and pinion and the regular cam motion options, the concealed cam motion door closers complete a comprehensive product portfolio, providing customers with high-spec solutions across a wide range of applications.

“Concealed cam motion closers are increasingly popular on building specifications thanks to their attractive aesthetics and functionality.

The options provided by the DC840 and DC860 means that we have simplified the specification process; all the benefits of the concealed cam motion in a choice of the two most requested sizes.”
