DORMA RTS88 Series Overhead 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. It can be easily installed in wood, aluminum, or hollow metal doors and frames, for single and double-acting doors.

  • Concealed installation
  • For single and double-acting doors
  • Dependable and easy to Install

Aesthetic advantages

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.

Vandalism protection

The RTS88 is an excellent replacement closer for problem entrances encountering vandalism of surface applied closers.

Benefits for the contractor

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.

Dormakaba RTS22 105 NHO SZ3 – Frequently Asked Questions

1) How heavy a door will the Dorma RTS22 overhead concealed closer handle?
Up to 250 lbs. That covers most full glass aluminum entrance doors. If your leaf is lighter and you only need a standard duty unit, the Norton Rixson 608 Series center hung concealed closer is rated to 200 lbs.
2) Do I have to specify left hand or right hand when ordering the RTS22 closer?
No handing to call out. The RTS22 is non-handed, so the same unit works on a left or right swinging opening. What you do have to specify is spring size, cushion stop degree, and whether you want hold open.
3) Which spring size should I order for a 3'-0" exterior aluminum entrance door?
For a 2'-6" to 3'-0" exterior door, SZ3 is the standard closing force. SZ4 is the strongest and covers 3'-0" to 3'-6" exterior or 3'-6" to 4'-0" interior doors. SZ2 is a light opening force option. If the opening has to meet a reduced opening force requirement, order BFE for exterior 3'-0" doors or BFI for interior 3'-0" doors.
4) The door is offset hung, not center hung - what overhead concealed closer should I use instead of the RTS22?
The RTS22 is a center hung end load unit, so it will not suit an offset hung aluminum door. For that pivot arrangement, the Norton Rixson 0608 Series is an offset hung overhead concealed closer for aluminum doors up to 200 lbs. Confirm the door leaf weight against that 200 lb figure before ordering.
5) What is the closest equivalent to the Dorma RTS22 overhead concealed closer from another manufacturer?
The Dorma RTS22 is a center hung, end load, single acting overhead concealed closer rated for doors up to 250 lbs. The nearest peer by mounting and capacity is the Norton Rixson 73 Series center hung overhead concealed closer, also rated 250 lbs and supplied with a cover plate, though the 73 is double acting where the RTS22 is single acting. If the opening is lighter, the Norton Rixson 608 Series is a center hung overhead concealed closer for 200 lb doors, and the Norton Rixson 700 Series is a center hung overhead concealed closer with the same 200 lb capacity.
6) My spec calls for a Grade 1 heavy duty concealed closer - what are the options?
Among the overhead concealed closers offered alongside the Dorma RTS22, the Grade 1 heavy duty units are the Sargent 268 with a cast iron body, the Sargent 269 with 180 degree opening capability, the Sargent 278 with an exposed arm, and the Norton Rixson 73 Series. Choose by mounting and arm type: the 278 uses an exposed arm rather than a fully concealed arm, and the 269 is the one to specify when the leaf must swing a full 180 degrees.
7) The entrance leaf is heavier than 200 lbs - which concealed closers are rated for it?
The Dorma RTS22 is rated for doors up to 250 lbs, and the Norton Rixson 73 Series center hung double acting unit carries the same 250 lb rating. The Norton Rixson 608, 700 and 0608 Series are standard duty units rated to 200 lbs, so they fall short for a heavier leaf.
8) Does the Dorma RTS22 come with a hold open, and what stop angle can I get?
Hold open is a build option, ordered yes or no. The cushion stop is available at either 90 degrees or 105 degrees, so pick the angle based on what the return wall or adjacent glass allows.
9) What extras can I add to an RTS22 order for a storefront install?
Three package choices: standard, with a 5mm extended spindle for thicker top rail or shim conditions, or with the 8563 frame cover plate added. Finish is selected separately and covers the 8653 cover frame, with prime coat, aluminum, statuary bronze, dull bronze, black, dark duradonic bronze, and gold available.
10) Why choose an overhead concealed closer like the RTS88 instead of a surface mounted one?
Two reasons drive it. The unit sits inside the head frame so nothing breaks up the look of the entrance, and there is no exposed body or arm for someone to pull on, which makes the RTS88 a common replacement at entrances where surface closers keep getting vandalized. Trade off: the frame prep has to be right, though most of the door and frame machining happens before the closer goes in, so there is less cutting on site.
11) Can the RTS88 closer go into wood or hollow metal doors, not just aluminum?
The RTS88 family installs in wood, aluminum, or hollow metal doors and frames. The RTS22 specifically is the aluminum door and frame, center hung end load configuration, so for wood or hollow metal you want the matching model in the series rather than this one.
12) Is there a simpler replacement closer body if I already have the RTS22 cement case and hardware in the door?
If the frame prep is already in place and you only need the operating unit, CRL Jackson offers overhead concealed closer bodies sold on their own: the 20-101M-03 regular duty body is a 90 degree non hold open unit and the 20-101M-01 is the 105 degree non hold open version, matching the two cushion angles the RTS22 is built in. A heavy duty body, 20-101M-09, is also offered in 105 degree non hold open. These are body-only items, so the existing case, spindle and cover must accept them - verify fit before substituting for a Dorma unit.
13) The RTS22 is ordered with a fixed spring size - is there a concealed closer with adjustable spring power instead?
Yes. The RTS22 is specified by spring size at time of order, with SZ2, SZ3 and SZ4 options plus barrier-free BFI and BFE sizes for 3'-0" doors. If you would rather set the power in the field, the CRL Jackson 20-101M-17 is an adjustable spring power overhead concealed closer body, 105 degree non hold open. It is a body-only unit, so the existing case and hardware have to accept it.
14) Will the Sargent 278 work as a drop-in substitute for a Dorma RTS22?
Not as a like-for-like swap. The RTS22 is a fully concealed center hung end load unit for aluminum door and frame applications, while the Sargent 278 is a heavy duty Grade 1 overhead concealed closer with an exposed arm - the arm remains visible at the head of the door. If the reason for specifying concealed hardware was appearance or vandal resistance, the 278 changes that. The Sargent 268, a Grade 1 heavy duty unit with a cast iron body, keeps the closer out of sight.
15) I need the door to stay open at 90 degrees - does the RTS22 do that, and what else will?
The RTS22 is built in both hold open and non hold open configurations, with 90 degree and 105 degree cushion angles, so a hold open unit can be specified directly. The CRL Jackson concealed closer bodies 20-101M-01, 20-101M-03, 20-101M-09 and 20-101M-17 are all non hold open units and will not provide that function.
16) Is the RTS22 closer suitable for a high traffic commercial entrance or is it a residential unit?
It is a commercial door control, built for aluminum storefront and similar openings and rated for doors up to 250 lbs. If you are standardizing across a building, note it is single acting only, so double acting pairs need a different unit.
