RTS88 Series Overhead Concealed Door Closers
Product # RTS88105NHOLSZ4
The DORMA RTS88 overhead concealed door closer offers the perfect solution to those seeking the aesthetic advantages of a concealed door closer.
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. 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 non-critical temperature compensating valves to ensure 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.
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 width of 3''-6" and interior doors up to a maximum width of 4' .
