7700ST

Push (Stop) Side Mount with Slide Arm and Track

Norton^® Series P7700ST door closers combine the exceptional door control of the Series 7700 door closer with the subtle appearance of a slide track and arm. Since the arm does not project, the overall installation exhibits a smooth uncluttered appearance.

The closer body is surface mounted to the push side of the door's top rail and the slide track is fastened to the frame soffit. They present an unobtrusive narrow profile installation. Also, since there is no hardware projecting when the door is closed, it provides a deterrent to vandalism.

The Series P7700ST closers are nonhanded. They feature 50% spring power adjustment; sweep speed, latch speed, backcheck cushioning and backcheck position control valve adjustment. They are supplied standard with a No. 7700P molded cover. They are also available with a No. 7700M metal (steel) cover or the No. 7700W wood-laminated steel cover. The metal cover and the arm assembly can be supplied in either a sprayed or plated finish. The slide track assembly is only available in Sprayed Finishes. See page 7700-3 for Finishes.

These door closers are available for either non-hold-open or hold-open operation. For doors requiring a maximum swing and/or hold open of 100° or less, the track has a spring cushion assembly to assist in bringing the door to a controlled dead stop. The hold-open track assembly also has an engage/disengage feature and hold-open tension adjustment. The ranges of door swing and the range of hold-open are as follows:

Non-Hold-Open with Spring Cushion Track 85° to 100°

Non-Hold-Open without Spring Cushion Track 85° to 125°

Hold-Open 85° to 100°

A telescoping arm assembly permits adjustment of the door swing and/or hold-open point in 3° increments within the ranges given above.
