  • 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 RTS14 105 NHO SZ3 – Frequently Asked Questions

1) What are the alternatives to the Dorma RTS14 for a center hung overhead concealed closer?
Norton Rixson's 73 Series is the closest peer we carry: center hung, double acting, heavy duty Grade 1, with a cover plate and a 250 lb door capacity, the same weight class as the RTS14. The Rixson 608 Series and 700 Series are also center hung concealed closers but are standard duty and rated for 200 lb doors, so they suit lighter openings. For an offset hung aluminum door rather than center hung, the Rixson 0608 Series is the one to look at. Sargent's 268 and 269 are heavy duty Grade 1 concealed closers, the 269 with 180 degree opening capability.
2) Which spring size should I order for a 3'-0" exterior aluminum entrance?
Five spring sizes are offered. SZ3 is the standard closing force for 2'-6" to 3'-0" exterior doors, so that is the usual pick for a 3'-0" entrance. Go to SZ4, the strongest, for 3'-0" to 3'-6" exterior or 3'-6" to 4'-0" interior doors. For interior openings SZ3 covers 3'-0" to 3'-6". SZ2 is a light opening force option, and BFE (exterior) and BFI (interior) are barrier free light opening force springs sized for a 3'-0" door width.
3) Does the RTS14 come with a hold open, and what degree stop can I get?
Hold open is an ordering choice: pick hold open or non hold open. The cushion stop is specified separately at either 90 degrees or 105 degrees. Decide both before ordering, since the closer is built to the combination you choose.
4) Does the RTS88 concealed closer only fit aluminum doors, or wood and hollow metal too?
The RTS88 closer itself installs in wood, aluminum, or hollow metal doors and frames. The RTS14 specifically is the package prepped for aluminum door and frame applications, center hung end load. If your opening is wood or hollow metal, order the RTS88 variant built for that prep instead.
5) My door is heavier than 200 lbs. Is the RTS14 enough, or do I need something else?
The RTS14 is rated to 250 lbs, so it covers doors the 200 lb class units do not. The Norton Rixson 608 and 700 Series center hung concealed closers we stock are listed at 200 lbs, so for a heavier leaf stay with the RTS14 or the Rixson 73 Series, which is also a 250 lb center hung unit.
6) What is the closest equivalent to the Dorma RTS14 overhead concealed closer from another manufacturer?
The Norton Rixson 73 Series is the nearest match. Like the RTS14, it is a center hung overhead concealed closer rated for 250 lb doors, it is double acting, and it comes with a cover plate. The 73 Series is listed as heavy duty and Grade 1. The RTS14 is a center hung end load unit for aluminum door and frame applications, non-handed, and orderable single or double acting with 90 degree or 105 degree cushion and an optional hold open.
7) My door is offset hung, not center hung - what concealed closer should I use instead of the RTS14?
The RTS14 is a center hung end load unit, so it is the wrong pivot geometry for 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, and is the one to specify when the door hangs on offset pivots.
8) I only need a replacement closer body for an existing concealed header - is the RTS14 the right buy?
The RTS14 is sold as a complete center hung end load closer for aluminum door and frame applications, with finish and cover frame options. If you are replacing only the mechanism in an existing header, the CRL Jackson 20-101M-01 and 20-101M-03 are sold as closer body only in brown, non hold open, in 105 degree and 90 degree versions respectively. A heavy duty body only version is the CRL Jackson 20-101M-09, 105 degree non hold open.
9) I need the door to open a full 180 degrees - will the RTS14 do it?
The RTS14 is offered with 90 degree or 105 degree cushion stops. For an opening that must swing to 180 degrees, the Sargent 269 is an overhead concealed closer with 180 degree opening capability, listed as heavy duty Grade 1.
10) I need ADA-level opening force on a barrier free entrance. What do I specify on the RTS88 closer?
Order it with a barrier free spring: BFI for interior doors or BFE for exterior doors, both rated as barrier free light opening force at a 3'-0" door width. If you only need a lighter pull without the barrier free rating, SZ2 is the light opening force spring.
11) What extra parts can I add to the RTS14 order to finish the installation?
Two add-ons are offered beyond the standard package: an 8563 frame cover plate, which dresses the header cutout, and a 5 mm extended spindle for applications where the standard spindle does not reach the top pivot arm.
12) Can I use this closer to replace a surface closer that keeps getting vandalized?
That is one of the reasons people move to the RTS88. With the closer concealed in the head frame there is no exposed body or arm to pry, and Dorma positions it as a replacement for problem entrances where surface applied closers are being vandalized. It also keeps the header clean where a surface unit would fight the architectural design.
13) I have a pair of double acting doors. Do I need to order a left and a right hand RTS14?
No. The RTS14 is non-handed, so the same unit works on either leaf, and it is built for single or double acting doors. Order one per leaf and specify the same spring size, cushion degree, and hold open option on both so the pair behaves alike.
14) Which concealed closer lets me adjust spring power in the field instead of ordering a fixed spring size?
The RTS14 is ordered to a fixed spring size at purchase - BFI and BFE barrier free light opening force for 3 ft interior and exterior doors, SZ2 light opening force, SZ3 standard closing force, and SZ4 strongest closing force. If you would rather set the power on site, the CRL Jackson 20-101M-17 is an adjustable spring power overhead concealed closer body, 105 degree no hold open.
15) Is the Sargent 278 a drop-in substitute for the RTS14 on a storefront where the closer must stay hidden?
No. The Sargent 278 is a concealed closer with an exposed arm, so part of the hardware remains visible on the door. The RTS14 is a fully concealed center hung end load unit for aluminum door and frame applications, which is the reason it is chosen where surface hardware would interfere with the architectural design. If concealment is the requirement, the 278 does not serve the same purpose.
16) What finishes are available on the RTS14 and its cover frame?
Seven finishes cover the closer and the 8653 cover frame: 600 prime coat, 689 aluminum, 690 statuary bronze, 691 dull bronze, 693 black, 695 dark duradonic bronze, and 696 gold. 689 aluminum and 693 black are the usual matches for clear and black anodized storefront.
17) Is a concealed closer like this harder to install on site than a surface closer?
Most of the labor moves off the job site. With the RTS88, the bulk of the door and frame preparation is done before the unit is installed, so there is less on-site machining than a field-mounted surface closer. The trade-off is that the prep has to be right the first time, since the closer sits inside the head frame rather than bolting onto the face of it.
