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.
