DormaKaba Architectural Hardware

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 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.
