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 RTS09 105 NHO SZ3 – Frequently Asked Questions

1) How heavy a door will the Dorma RTS09 concealed closer handle?
The RTS09 is rated for doors up to 250 lbs. That covers most aluminum entrance leaves and heavier glass or metal 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 need to order a left hand or right hand version of the RTS09?
No handing to specify. The RTS09 is non-handed, so one unit works on either a left or right swinging leaf, and it will run single acting or double acting. That is useful if you are standardizing spare closers across a building.
3) Is the RTS09 for center hung or offset pivoted doors?
Center hung, end load. It is built for a center hung aluminum door and frame application, so the pivot point sits on the door centerline. If your opening is offset pivoted, this is the wrong unit, look at an offset hung concealed closer such as the Norton Rixson 0608 Series instead.
4) Which spring size should I pick for a 3 foot exterior aluminum entrance?
Five spring sizes are offered on the RTS09. SZ3 is the standard closing force and covers 2'-6" to 3'-0" exterior doors and 3'-0" to 3'-6" interior doors. SZ4 is the strongest, for 3'-0" to 3'-6" exterior and 3'-6" to 4'-0" interior. SZ2 is a light opening force option. For reduced opening force on a 3'-0" door there are two barrier free sizes: BFE for exterior and BFI for interior.
5) Is the RTS09 only for aluminum doors, or will it go in wood and hollow metal too?
The RTS09 package is specified for aluminum door and frame application. The RTS88 family as a whole installs in wood, aluminum, or hollow metal doors and frames, so if your opening is wood or hollow metal you want the RTS88 variant prepped for that substrate rather than this aluminum package.
6) I need reduced opening force for accessibility on an interior door. Which RTS09 do I order?
Order spring size BFI, the barrier free light opening force option for interior doors at 3'-0" width. For an exterior leaf of the same width the equivalent is BFE. Both are separate from SZ2, which is described simply as light opening force rather than barrier free.
7) What is the closest equivalent to the Dorma RTS09 overhead concealed closer from another manufacturer?
The Norton Rixson 73 Series is the nearest match. Like the RTS09, it is a center hung double acting overhead concealed closer and it is rated for 250 lb doors, the same door weight the RTS09 carries. The 73 Series is a heavy duty Grade 1 unit and comes with a cover plate, where the RTS09 offers the 8563 frame cover plate as a package option alongside its standard build.
8) I need a concealed closer that opens to 180 degrees. Will the RTS09 do that?
The RTS09 is built with a cushion at either 90 degrees or 105 degrees. For a 180 degree opening, the Sargent 269 is an overhead concealed closer with 180 degree opening capability, a heavy duty Grade 1 unit in the 269 Series.
9) Can I get the RTS09 with hold open, and what does the cushion degree mean?
Hold open is an ordering choice, yes or no. Separately you pick the cushion stop point, 90 degrees or 105 degrees, which is where the closer cushions the swing at the end of the opening arc. Pick the cushion angle that matches how far the leaf can safely travel against adjacent walls or sidelites.
10) What extra parts can I add to the RTS09 order?
Three package options: Standard, Add 8563 Frame Cover Plate, or With 5mm Extended Spindle. The cover plate is worth specifying when the header prep needs to be concealed on an existing frame, and the extended spindle handles a top rail or pivot geometry that needs the extra 5mm of reach.
11) Our surface closers keep getting vandalized at the front entrance. Is a concealed closer like this a fix?
That is one of the main reasons the RTS88 family gets specified. With the closer body concealed in the header there is no exposed arm or body to pry, kick, or unscrew, which is why it is used as a replacement on problem entrances. It also keeps the hardware out of sight where a surface unit would interfere with the architectural look.
12) What are the alternatives to the Dorma RTS09 for a center hung double acting entrance?
For a double acting center hung opening at the same 250 lb door capacity, the Norton Rixson 73 Series center hung double acting concealed closer with cover plate is the closest cross-brand equivalent, and it is listed as Heavy Duty, Grade 1. Sargent's 268 concealed closer is another heavy duty Grade 1 option, with a cast iron body, and the Sargent 269 is the one to look at if you need 180 degree opening. CRL Jackson 20-101M body-only units are a lighter route when you are replacing just the closer body in an existing prep.
13) Is there a lighter duty concealed closer if my door is under 200 pounds?
Yes. The Norton Rixson 608 Series and the 700 Series are both center hung overhead concealed closers rated as standard duty for 200 lb doors. The Dorma RTS09 is specified to 250 lbs, so if your leaf is well under 200 lbs the standard duty Rixson units cover the opening.
14) I only need to replace the closer body in an existing concealed header. Do I have to buy the full RTS09?
The RTS09 is sold as a complete closer with spring size, cushion angle, hold open and finish selected at order. If your existing header prep is a CRL Jackson concealed installation, CRL Jackson sells body only units such as the 20-101M-01 regular duty 105 degree non hold open and the 20-101M-03 regular duty 90 degree non hold open, which match the two cushion angles the RTS09 is offered in.
15) The RTS09 requires me to pick a spring size up front. Is there a closer with adjustable spring power instead?
The CRL Jackson 20-101M-17 is an adjustable spring power overhead concealed closer body, 105 degree no hold open, so the closing force is set in the field rather than at order. The Dorma RTS09 is ordered with a fixed spring size chosen from BFI and BFE barrier free options, SZ2 light opening force, SZ3 for 3'-0" to 3'-6" interior doors, and SZ4 for 3'-6" to 4'-0" interior doors.
16) Is the Sargent 278 a direct substitute for the Dorma RTS09?
Not a like for like swap. The Sargent 278 is an overhead concealed closer with an exposed arm, so the arm shows at the door. The RTS09 is a fully concealed center hung end load unit, chosen specifically where a visible closer would interfere with the architectural design. Both are concealed body units, but the visible hardware at the head differs.
17) What finishes does the RTS09 closer and its cover frame come in?
Seven finish choices, and the finish carries the 8653 cover frame with it: 600 Prime Coat, 689 Aluminum, 690 Statuary Bronze, 691 Dull Bronze, 693 Black, 695 Dark Duradonic Bronze, and 696 Gold. 689 Aluminum is the usual match for clear anodized storefront; the bronzes match dark anodized frames.
18) How much on-site machining does a concealed closer like this add to the job?
Less than you would expect. Most of the door and frame preparation for the RTS88 is done before the unit goes in, so field machining is minimal. Practically, that means getting the header and door prep right up front is what decides the install, not cutting on site.
19) What heavy duty option is there if the CRL Jackson regular duty body is not enough for my opening?
CRL Jackson offers the 20-101M-09 heavy duty overhead concealed closer body only, 105 degree no hold open, above the regular duty 20-101M-01 at the same 105 degree swing. The Dorma RTS09 covers heavier leaves directly, being specified for doors up to 250 lbs in a center hung end load aluminum door and frame application.
