Smooth Operators
Closing in on Automatic Door Closers and Hardware

When the door opens as a pedestrian approaches, or is kept from clipping people’s heels as they walk past, there is probably little thought given to the hardware that makes these functions possible. That’s exactly the way it should be—automatic sensors and closers and other door hardware are intended to operate smoothly so that people entering and exiting don’t even think about them. However, we at USGlass do think about the hardware that goes into making these doors automatic. That’s why we’re spotlighting just a few of the products designed to stay out of sight and out of mind, and the doors that wouldn’t work without them. 

A Safe New NABCO Sensor Swings In
NABCO Entrances Inc. in Muskego, Wis., has added extra pedestrian protection to its Acugard line of low-energy swing door sensors. The Acugard 3 LE is a bar-type sensor that can be mounted on the approach side of the door to prevent it from closing on slower moving traffic until all people are completely through the entrance path of the door. The sensor also can be mounted on the swing side to stop the door from opening in the event that someone is in the swing path while a pedestrian is approaching. The device handles AC-DC power sources that can interface and multiple types of low-energy doors. www.nabcoentrances.com

Low-Profile Swing Door Operator Offers Modern Look
The low profile of the new CD 80 swing door operator from DORMA Entrance Systems in Reamstown, Pa., makes the device suitable for mounting on standard door systems. In addition, the unit’s low weight allows it to fit directly onto the door leaf or top jamb without causing excessive hinge strain. According to the company, it’s easy to install; installers need only latch the operator onto the mounting plate after the plate has been attached.

The CD 80 operator is a quiet solution for noise-sensitive locations. Its tight engineering tolerances reduce vibrations during door operation, resulting in silent function when automatically opening and closing a door.

In addition, the operator offers power assistance and an extended hold-open function that allows the door to remain open at an adjustable angle for up to 10 minutes. www.dorma-usa.com
