Architects are often challenged to design buildings that are both beautiful and functional, down to the last detail. The

DORMA RTS88 overhead concealed door closer offers the perfect solution for those who prefer the aesthetic advantages of a concealed door closer.  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. The RTS88 may 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 encountering vandalism of surface applied closers.  The RTS88 Series overhead concealed door closer has a compact body size which fits into a 1-3/4" × 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 90° or 105° 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 cushion at 90° or 105°, depending on the model selected, helps protect the door, frame, and adjoining structure.

Always use an auxiliary stop in conjunction with RTS88 installations.

The RTS88 may be used on doors weighing up to a maximum of 250 lb (interior) or 200 lb (exterior), including all hardware. The closer may be used on 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 90° or 105°.
