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 RTS19 105 NHO SZ3 – Frequently Asked Questions

1) Will the Dorma RTS19 concealed closer work on a center hung aluminum storefront door?
That is exactly what the RTS19 is built for. It is the center hung, end load version of the RTS88 concealed closer, packaged for aluminum door and frame applications. Center hung means the pivot sits inboard of the door edge on the door centerline, so the closer body mounts in the head of the frame over the pivot point. If your opening is offset pivoted rather than center hung, this is the wrong configuration.
2) How heavy a door can the Dorma RTS19 concealed closer handle?
Up to 250 lbs of door. That covers most full-height aluminum entrance doors and mid-weight glass doors. If you are hanging something heavier than that, step up to a floor closer rather than an overhead concealed unit.
3) Which spring size should I order for a 3'-0" exterior aluminum entrance?
For a 3'-0" exterior door, SZ3 is the standard closing force choice. The full ladder on the RTS19 runs SZ2 (light opening force), SZ3 (3'-0" to 3'-6" interior, 2'-6" to 3'-0" exterior), and SZ4 (strongest, 3'-6" to 4'-0" interior, 3'-0" to 3'-6" exterior). If you need reduced opening force for accessibility, order BFE for a 3'-0" exterior door or BFI for a 3'-0" interior door.
4) Does the Dorma RTS19 need to be ordered left hand or right hand?
No handing to specify. The RTS19 is non-handed and works single acting or double acting, so the same unit covers a swing-in, swing-out, or full double acting opening. What you do have to decide at order time is cushion stop degree, hold open, and spring size.
5) What else could I use instead of the Dorma RTS19 for a center hung concealed application?
Within center hung overhead concealed closers, the Norton Rixson 73 Series is the closest match on capacity, a heavy duty Grade 1 double acting unit rated for 250 lb doors and supplied with a cover plate. The Norton Rixson 608 Series and the 700 Series are also center hung concealed closers but are standard duty and rated for 200 lb doors, so they suit lighter openings. Sargent's 268 is a heavy duty Grade 1 concealed closer with a cast iron body, and the 269 is the heavy duty option where you need 180 degree opening.
6) My door is offset hung, not center hung. What concealed closer should I use instead of the RTS19?
The RTS19 is prepared for a center hung end load application, so it will not suit an offset hung opening. The Norton Rixson 0608 Series is an offset hung overhead concealed closer for aluminum doors up to 200 lbs, listed as standard duty. Confirm the door leaf weight against that 200 lb figure before ordering.
7) The RTS19 cushions at 90 or 105 degrees. What if I need the door to swing much wider?
The RTS19 is ordered with either a 90 degree or a 105 degree cushion. Where a wider swing is required, the Sargent 269 is an overhead concealed closer with 180 degree opening capability, listed as heavy duty Grade 1 in the 269 Series.
8) I need a reduced opening force closer for an accessible entrance. Does a concealed unit handle that?
The RTS19 is ordered by spring size, including BFE for barrier free light opening force on exterior doors at 3'-0" width and BFI for barrier free light opening force on interior doors at 3'-0" width, plus SZ2 light opening force, SZ3 standard closing force, and SZ4 for the widest leaves. If you would rather field-adjust the power, the CRL Jackson 20-101M-17 is an adjustable spring power concealed closer body with a 105 degree non hold-open function.
9) What is the difference between the 90 degree and 105 degree cushion on the RTS19?
The cushion is the built-in backcheck/stop point, and you pick the one that matches how far the door can safely swing. Order the 90 degree cushion where a return wall, sidelite, or adjacent door limits travel; order 105 degrees where the opening has clearance for a wider swing. Both are offered on the RTS19 with or without hold open.
10) Can I get the RTS19 with a hold open feature?
Yes, hold open is an orderable option on the RTS19, and it is also offered as a plain non hold open closer. Pick hold open for openings where deliveries or moving traffic need the door parked open; skip it on doors that have to self close every cycle, such as anything on a smoke or stair opening.
11) What is the 8563 frame cover plate option and when do I need it?
The RTS19 can be ordered standard, with the 8563 frame cover plate added, or with a 5mm extended spindle. The cover plate is the option to take on a retrofit where the existing frame prep is larger or rougher than the new closer body and you need the head cleaned up. The extended spindle package is for door and pivot geometry that puts the top pivot point further from the closer than the standard spindle reaches. Finishes, including the 8653 cover frame, run prime coat 600, aluminum 689, statuary bronze 690, dull bronze 691, black 693, dark duradonic bronze 695, and gold 696.
12) Is an overhead concealed closer better than a surface closer for a vandalism-prone entrance?
For entrances where surface closers keep getting torn off or tampered with, the RTS88 style overhead concealed unit is the usual fix, because the body sits inside the head of the frame with nothing exposed to grab. It is also the answer when a surface arm would fight the architectural look of the opening. Trade-off: most of the door and frame machining has to be done up front, so it suits new frames or a planned retrofit better than a same-day swap.
13) Can the RTS88 concealed closer be used on wood or hollow metal doors, or only aluminum?
The RTS88 closer installs in wood, aluminum, and hollow metal doors and frames. The RTS19 specifically is packaged for the aluminum door and frame application with the center hung end load arrangement, so for a wood or hollow metal opening you want the RTS88 variant prepped for that material.
14) I need a closer body only to drop into an existing concealed pocket. Does the RTS19 work for that?
The RTS19 is supplied as a closer configured for aluminum door and frame center hung end load applications, with package options that include a standard build, an 8563 frame cover plate, or a 5mm extended spindle. If you specifically need a body-only replacement, CRL Jackson offers concealed closer bodies: the 20-101M-01 regular duty 105 degree non hold-open, the 20-101M-03 regular duty 90 degree non hold-open, the 20-101M-09 heavy duty 105 degree non hold-open, and the 20-101M-17 adjustable spring power 105 degree non hold-open.
15) I need hold-open on a concealed closer. Which options actually offer it?
The RTS19 is ordered with or without hold open, so a hold-open unit is available 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, so they are not substitutes if hold open is required.
16) Does the Sargent 278 work as a concealed replacement for the RTS19 on a storefront entrance?
Not as a like-for-like. The Sargent 278 is an overhead concealed closer with an exposed arm, so the arm remains visible on the door face. The RTS19 is a fully concealed unit for aluminum doors and frames and is often chosen where a surface applied or exposed mechanism would interfere with the architectural design or be a target for vandalism.
17) Can I match the RTS19 cover to the bronze storefront on my other entrances?
Seven finishes are offered, and the 8653 cover frame is finished to match: 600 prime coat, 689 aluminum, 690 statuary bronze, 691 dull bronze, 693 black, 695 dark duradonic bronze, and 696 gold. For a dark bronze storefront, 695 dark duradonic bronze or 690 statuary bronze are the usual picks; 600 prime coat is the one to order when the closer is being field painted to match a custom color.
18) Is the Dorma RTS19 concealed closer suitable for commercial traffic or is it a residential unit?
It is a commercial door control, rated to 250 lb doors and built for entrance duty where a surface closer would be damaged or would spoil the elevation. Property managers standardizing a building can run the same non-handed unit across single acting and double acting openings and just change spring size to suit door width.
