Control with Flexibility from Adams Rite


Adams Rite, part of ASSA ABLOY Security Solutions, an ASSA ABLOY company, has launched a variable spring strength version of its popular ARC-51N transom door closer, ideal for facilitating effective building management.

The new transom door closer features an adjustable spring, enabling a simple change between closing strengths EN 1-4, under EN1154. This ensures the door closes smoothly and securely, while the opening force is kept to a minimum for safe and inclusive access.

Having been tested to 500,000 cycles, Adams Rite’s variable speed transom closer has proven durability, as well as cost-efficiency, making it ideal for applications on a tight budget, from public sector and commercial builds to healthcare and educational facilities. 

The new unit shares the same footprint as the current fixed spring variant, making it an ideal retrofit product. With quick and simple installation, the closer limits disruption to the day-to-day operations of the building upon fitting. 

Andy Stolworthy, Product Manager for Adams Rite, said: “When a doorset has to withstand heavy through-traffic – as you’d see in a hospital corridor or the entrance to a classroom – it’s essential that hardware is durable and long-lasting.

“The variable speed transom door closer at once provides peace-of-mind that it will endure, as well as the flexibility for effective installation and upkeep.

“A word of caution, if the doorset is specified to meet the opening force requirements of Approved Document M, a CAM motion unit should be used, which Adams Rite can also supply.”

Adams Rite is the leading supplier of aluminium door locking, electric locking and escape devices, supplying the top OEM door manufacturers worldwide. The company is part of ASSA ABLOY Security Solutions, a division of ASSA ABLOY, the global leader in door opening solutions.
