n Easy Adjustment/Installation
The air pressure and timing cycle are easily adjustable to meet the
need of a specific installation. Because the control box can be located
anywhere within 100 linear tubing feet from the controlled door for the
7900 Series or within 50 linear tubing feet for the 7980 Series, they can
be placed in easily accessible locations. Convenient features such as
sequential operation of vestibule doors are available.
n Multiple Mounting Configurations
Available in three different mounting configurations:
- Concealed in the frame (2610 Series).
- Top Jamb Surface Mounted on the pull side of the door (4810 Series).
- Top Jamb Surface Mounted on the push side of the door
(4820 Series).
- Door Mounted, Parallel Arm on the push side of the door
(4840 Series).
