  • 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 RTS04 105 NHO SZ3 689 – Frequently Asked Questions

1) Will the Dorma RTS88 RTS04 closer work on a wood door in a hollow metal frame?
That is exactly what the RTS04 package is built for. It is the center hung side load version configured for wood door and steel frame application, and the RTS88 body itself installs in wood, aluminum, or hollow metal doors and frames. The door must be center hung, not offset pivoted.
2) How heavy a door can the Dorma RTS88 RTS04 concealed closer handle?
Rated to 250 lbs of door weight. If your leaf is heavier than that, this is the wrong control for the opening.
3) Do I need to order a left hand and a right hand version of the RTS04?
No. The RTS04 is non-handed, so one unit covers either swing direction, and it works single acting or double acting. That makes it simple to stock one part for a building with mixed openings.
4) Which spring size should I pick for a 3'-0" exterior door with the RTS88?
SZ3 is the standard closing force covering 2'-6" to 3'-0" exterior doors and 3'-0" to 3'-6" interior doors. Go to SZ4 for 3'-0" to 3'-6" exterior or 3'-6" to 4'-0" interior. If the opening needs reduced opening force, BFE is the barrier free option for a 3'-0" exterior door and BFI the interior equivalent; SZ2 is the other light opening force choice.
5) What do I have to specify when ordering a Dorma RTS04 concealed closer?
Five choices settle the order: spring size (BFE, BFI, SZ2, SZ3 or SZ4), cushion stop at 90 or 105 degrees, hold open or non hold open, finish, and package option. Package option is Standard, Less Mounting Channel if the channel is already in the door, or With 5mm Extended Spindle where the pivot point sits deeper.
6) What are the alternatives to the Dorma RTS88 for a center hung concealed closer?
For a comparable center hung application, the Norton Rixson 73 Series is a heavy duty Grade 1 center hung double acting concealed closer also rated to 250 lbs. The Norton Rixson 608 Series and 700 Series are center hung standard duty units rated to 200 lb doors, so they suit lighter leaves. Sargent's 268 and 269 are heavy duty Grade 1 overhead concealed closers, the 269 with 180 degree opening capability. If the door is offset pivoted rather than center hung, the RTS04 is the wrong prep and the Norton Rixson 0608 Series offset hung closer for aluminum doors up to 200 lbs is the one to look at.
7) What is the closest equivalent to the Dorma RTS04 center hung overhead concealed closer from another manufacturer?
The Norton Rixson 73 Series is the nearest match. Like the RTS04, it is a center hung overhead concealed closer rated for 250 lb doors and it is double acting, and it ships with a cover plate. It is listed as heavy duty and Grade 1. The RTS04 covers the same center hung side load position for wood door and steel frame openings and is non-handed, so it serves single or double acting leaves without a hand call-out.
8) My door is offset hung, not center hung - what concealed closer should I use instead of the RTS04?
The RTS04 is built for center hung side load openings in wood doors and steel frames, so an offset pivot opening needs a different unit. The Norton Rixson 0608 Series is an offset hung overhead concealed closer for aluminum doors up to 200 lbs and is listed as standard duty. Confirm your leaf weight against that 200 lb figure, since the RTS04 is rated to 250 lbs.
9) I need a concealed closer that opens to 180 degrees - does the Dorma RTS04 do that?
The RTS04 is supplied with a 90 degree or 105 degree cushion stop, so its cushioning point is set at one of those two angles. If the opening requires a full 180 degree swing, the Sargent 269 is an overhead concealed closer specified with 180 degree opening capability; it is heavy duty and Grade 1.
10) Should I use an overhead concealed closer or a surface mounted one?
The RTS88 concealed unit is the choice when a surface closer would clash with the architecture or when the entrance keeps getting vandalized, since nothing is exposed on the door face to pry or strip. It also cuts site work, because most of the door and frame prep happens before the unit goes in. A surface closer stays easier to service and adjust later without pulling the door down, so for a back of house opening nobody looks at, surface is usually the simpler call.
11) Should I order the RTS04 with 90 degree or 105 degree cushion?
Pick the cushion to match how far the door is allowed to swing before something behind it gets hit. 105 degrees gives the wider opening; 90 degrees stops it sooner where a return wall, side lite or adjacent door limits travel. It is a per-unit choice on the RTS04, so confirm the swing clearance at the opening before you order.
12) Can I get the Dorma RTS04 closer to hold the door open?
Yes, hold open is an orderable option on the RTS04, and non hold open is the alternative. Choose non hold open for any door that has to stay closed as a matter of function, such as a smoke or corridor door.
13) I only need the closer body, not the mounting channel. Can I order that?
Yes. The RTS04 is offered Less Mounting Channel, which is what you want when the channel is already set in the door from a previous install or was supplied with the door. Standard includes it. There is also a With 5mm Extended Spindle version for openings that need the extra spindle reach.
14) Is a CRL Jackson overhead concealed closer body a drop-in replacement for a Dorma RTS04?
No. The CRL Jackson 20-101M units are sold as closer body only - for example the 20-101M-01 regular duty body with 105 degree no hold-open and the 20-101M-03 with 90 degree no hold-open - so they are intended to replace a body inside existing Jackson hardware, not to package a complete RTS88 installation. The RTS04 is ordered as a full unit with standard, less mounting channel, or 5mm extended spindle packaging, and it can be specified with or without hold open, which the 20-101M-01 and -03 are not.
15) What is a lighter duty center hung concealed closer if I do not need the RTS04's 250 lb capacity?
The Norton Rixson 608 Series and the Norton Rixson 700 Series are both center hung overhead concealed closers rated for 200 lb doors and listed as standard duty. The Dorma RTS04 is rated to 250 lbs and is offered in five spring sizes from barrier free interior and exterior openings through SZ4 for 3'-6" to 4'-0" interior doors, so it reaches a wider force range on heavier leaves.
16) I need a concealed closer with an exposed arm rather than a fully concealed closer - what should I order?
The Sargent 278 is an overhead concealed closer with an exposed arm, listed as heavy duty and Grade 1. The Dorma RTS04 is a concealed installation unit intended for openings where surface applied hardware would interfere with the architectural design, and it is also used to replace surface closers on entrances that see vandalism.
17) Can I get an adjustable spring power concealed closer instead of picking a fixed spring size?
The CRL Jackson 20-101M-17 is an adjustable spring power overhead concealed closer body with a 105 degree non hold-open function. The Dorma RTS04 instead uses fixed spring sizes selected at order: BFE and BFI barrier free light opening force for 3'-0" doors, SZ2 light opening force, SZ3 standard closing force, and SZ4 for the heaviest leaves, so you specify the force up front rather than dialing it in.
18) What finishes does the Dorma RTS88 RTS04 come in?
Seven: 600 prime coat, 689 aluminum, 690 statuary bronze, 691 dull bronze, 693 black, 695 dark duradonic bronze, and 696 gold. Prime coat is the one to take if the cover is being painted to match the frame on site.
19) Is the Dorma RTS88 RTS04 suitable for a commercial entrance or is it a residential closer?
It is a commercial rated overhead concealed closer, built for entrances carrying doors up to 250 lbs and for openings where surface applied closers get abused. Dorma calls out its use as a replacement on problem entrances.
20) Which concealed closer has a cast iron body for a high-abuse entrance?
The Sargent 268 is specified with a cast iron body and is listed as heavy duty, Grade 1. The Dorma RTS04 is a commercial concealed closer rated to 250 lb doors and is frequently used as a replacement where surface applied closers have been vandalized, since the operator sits inside the frame.
21) Is the CRL Jackson heavy duty 20-101M-09 an alternative to the Dorma RTS04 for a heavier door?
The CRL Jackson 20-101M-09 is a heavy duty overhead concealed closer body only with a 105 degree non hold-open swing, so it is a body replacement in a 105 degree configuration with no hold open option. The Dorma RTS04 is ordered as a complete unit for center hung side load wood door and steel frame openings, is non-handed, and can be specified with either a 90 or 105 degree cushion and with or without hold open.
