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 RTS02 105 NHO SZ3 – Frequently Asked Questions

1) How heavy a door can the Dorma RTS88 RTS02 concealed closer handle?
The RTS02 overhead concealed closer is rated for doors up to 250 lbs. That covers most aluminum entrance leaves and heavier glass or hollow metal doors. If your leaf is lighter, spring size is the thing that actually decides feel: SZ3 is the standard closing force for 3'-0" to 3'-6" interior or 2'-6" to 3'-0" exterior doors, and SZ4 is the strongest, for 3'-6" to 4'-0" interior or 3'-0" to 3'-6" exterior.
2) Do I need to specify a hand for the RTS02 concealed closer?
No handing to specify. The RTS02 is non-handed and works single acting or double acting, so the same unit covers a left or right swing and a door that swings both ways. What you do have to call out on the order is spring size, cushion stop angle, and whether you want hold open.
3) Which spring size should I order for an ADA-type light opening force entrance?
Two barrier-free springs are offered on the RTS02: BFE for light opening force on exterior doors at a 3'-0" door width, and BFI for the same on interior doors at 3'-0". There is also SZ2, a light opening force spring. Pick BFE or BFI when reduced opening force is the requirement, SZ3 or SZ4 when the door needs to close reliably against wind or stack pressure.
4) My door is offset hung, not center hung - what concealed closer should I use instead of the RTS02?
The RTS02 is a center hung side load unit for aluminum doors and frames, so it is not the right pick for an offset pivot opening. The Norton Rixson 0608 Series is an offset hung overhead concealed closer for aluminum doors up to 200 lbs, which is the geometry you need there. Confirm your door leaf weight against that 200 lb figure before you commit.
5) Will a CRL Jackson overhead concealed closer body drop into a Dorma RTS88 prep?
Treat them as separate systems, not interchangeable parts. The CRL Jackson units such as the 20-101M-01 and 20-101M-03 are sold as closer body only in regular duty, 105 degree and 90 degree non hold open respectively, with a heavy duty 105 degree non hold open body offered as 20-101M-09. They are replacement bodies for CRL Jackson prep. The Dorma RTS02 is a complete center hung side load closer for aluminum door and frame, ordered with its own spring size, cushion angle, and hold open or no hold open option.
6) What is the closest equivalent to the Dorma RTS88 RTS02 overhead concealed closer from another manufacturer?
The Norton Rixson 73 Series is the nearest match. Like the RTS02 it is a center hung double acting overhead concealed closer, it is rated to a 250 lb door, and it is offered with a cover plate. The RTS02 is likewise rated for doors up to 250 lbs and handles single or double acting openings. Where they differ in the way you order them: the RTS02 is configured by spring size, from BFI and BFE barrier free light opening force up to SZ4 for 3'-6" to 4'-0" interior doors, while the Rixson 73 is catalogued as a heavy duty Grade 1 unit by series.
7) I need a door that swings past 105 degrees - does the RTS02 do that, or should I look elsewhere?
The RTS02 is built around a 90 degree or 105 degree cushion stop, so those are the swing points it is set up for. If the opening has to go further, the Sargent 269 is a heavy duty Grade 1 overhead concealed closer with 180 degree opening capability. That is the change worth making rather than trying to push the RTS02 past its cushion setting.
8) What is the difference between the 90 degree and 105 degree cushion on the RTS02?
The cushion is the built-in dead stop angle. Order 90 degrees where a wall, sidelite, or adjacent leaf limits the swing, and 105 degrees where you want a wider opening before the closer cushions the door. Both angles are offered with or without hold open.
9) Can I get the RTS88 RTS02 with hold open?
Yes, hold open is a build option on the RTS02, and it pairs with either the 90 degree or 105 degree cushion. For doors that must self close every cycle, order the no hold open version instead.
10) What package options are there besides the standard RTS02 closer?
Three ways to order it: standard, with a 5mm extended spindle for thicker door or rail conditions, and with an 8563 frame cover plate in aluminum finish. The cover plate is the one to add when the header prep will be visible and you want it finished off.
11) Is a concealed closer worth it over a surface closer on a problem entrance?
That is exactly the case the RTS88 is aimed at. It goes in the header rather than on the face of the door, so there is nothing exposed to pry, hang on, or unbolt, which makes it a common replacement on entrances where surface closers keep getting vandalized. It also keeps the door line clean where a surface unit would fight the architecture.
12) Can the RTS88 be used in wood or hollow metal doors, or only aluminum?
The series installs in wood, aluminum, or hollow metal doors and frames. This particular RTS02 package is configured for aluminum door and frame, center hung side load.
13) If I do not want to commit to a spring size up front, is there an adjustable alternative to the RTS02?
The CRL Jackson 20-101M-17 is an adjustable spring power overhead concealed door closer body, 105 degree non hold open, so the closing force is set after the fact rather than chosen at order time. The Dorma RTS02 is specified by fixed spring size instead - BFI and BFE for barrier free light opening force on 3'-0" doors, SZ2 light, SZ3 for 3'-0" to 3'-6" interior and 2'-6" to 3'-0" exterior doors, and SZ4 for the widest leaves. Pick the RTS02 spring size against your door width and whether the opening is interior or exterior.
14) How much on-site machining does installing an RTS88 concealed closer take?
Most of the door and frame preparation is done before the unit arrives on site, so the field work is limited compared with cutting in a closer from scratch. That is the main reason contractors accept concealed units on schedule-driven jobs.
