Logic 5.0 The Next Generation of Commercial Door Operators
Gearhead Sliding (GSD) style commercial door operators employ lubricated gears for heavy industrial, high cycle applications. GSD-style operators offer functionality that is similar to GT-style operators, but are used on single and bi-parting sliding doors. These operators are directly attached to drive and control the door. GSD operators are mounted directly above the door.
Safety and Security
UL 325 requires all commercial door operators to be either constant pressure to close or be equipped with a primary external monitored entrapment protection device.
