Reduce Operation and Maintenance Costs with Spring Assist Arm System from DORMA
REAMSTOWN, Pa. - The S-DS and S-IS Spring Assist Arm Systems from DORMA Architectural Hardware are designed to control doors in high traffic applications such as educational facilities, sports arenas, retail stores, hotels and theaters.
The Spring Arm Systems prevent the door from slamming into an adjacent wall, which could damage the wall, door closer or other hardware on or around the opening. By minimizing the collateral effects of high volume or abusive pedestrian traffic through doors, the system can reduce operation and maintenance costs. The quiet operation avoids metal-to-metal contact to lessen or completely eliminate operation noise.
The Spring Assist Arm Systems are available in three mount types – regular, top jamb and parallel arm. DORMA is the only manufacturer to offer spring assist products for regular mount applications.
The system features DORMA’s Tight Lock™ arm system, which ensures a secure mechanical connection between the closer pinion and main arm, and can be templated for various stop points at 85, 90, 100 and 110 degrees.
