 The RTS88 is designed to give lasting, dependable service
where surface applied units and other types of closers are
not suitable, or would interfere with the architectural design.
It can be easily installed in wood, aluminum, or hollow metal
doors and frames, for single and double-acting doors.
Contractors appreciate the RTS88 closer, because the
majority of door and frame preparation is done prior to
installation of the unit, resulting in less on-site machining.
The RTS88 is also an excellent replacement closer for
problem entrances.
The RTS88 Series overhead concealed door closer has a
compact body size which fits into a 1-3/4" x 4" header for
aluminum frames and is also easily adaptable to wood and
hollow metal frame configurations.
Openings fitted with the RTS88 are capable of 90º or 105º
maximum opening door swing, trim conditions permitting.
Sweep and latch closing speeds are controlled by two
noncritical temperature compensating valves to insure
constant closing speeds even under the most extreme
temperature conditions.
A built-in pressure relief valve
protects the closer from abuse due to forced closing. A
positive stop at 90º or 105º, depending on the model
selected, combined with a mechanical backcheck, hinder the
forceful or abusive opening of the door and help protect the
door, frame, and adjoining structure.
Always use an auxiliary stop in conjunction with RTS88
installations.
The RTS88 is capable of accommodating doors weighing
up to a maximum of 250 pounds. The closer can handle
exterior doors up to a maximum 3'-6" width and interior doors
up to a maximum 4' width.
A complete line of accessories is available for wood,
aluminum, and hollow metal applications, both single and
double-acting center hung doors, and hinged or offset pivoted
single-acting doors.
Other accessories include cover plates for wood,
aluminum, and hollow metal frames and extended spindles
for increased clearances at the top of the door. Optional hold
open units are available, effective at either 90º or 105º. |
