  • 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 RTS06 105 NHO SZ3 626 – Frequently Asked Questions

1) Will the Dorma RTS06 concealed closer work on a wood door in an aluminum frame?
That is exactly the configuration the RTS06 is packaged for: center hung, side load, wood door with an aluminum frame. It mounts concealed in the head of the frame rather than on the door face, and it handles doors up to 250 lbs. If your door is aluminum or hollow metal, or the hanging is offset rather than center hung, you want a different RTS package.
2) Do I have to order the RTS06 handed for a left or right swing door?
No handing to specify. The RTS06 is non-handed and works single acting or double acting, so the same unit covers a door swinging one way or a door swinging both ways. That makes it easy to stock one unit for several openings in a building.
3) Which spring size should I pick for a 3 foot exterior entrance door?
Two choices fit a 3'-0" exterior leaf. SZ3 is the standard closing force covering 2'-6" to 3'-0" exterior doors (and 3'-0" to 3'-6" interior). If the opening has to meet a barrier free opening force requirement, order BFE, the barrier free light opening force spring for exterior doors at 3'-0" width. For a 3'-0" to 3'-6" exterior door step up to SZ4, the strongest closing force.
4) Can I get the Dorma RTS06 with hold open, and what does the 90 or 105 degree cushion mean?
Hold open is an order option: pick Yes for a hold open unit or No for non hold open. Separately you choose the cushion stop point, 90 degrees or 105 degrees, which is where the closer cushions the door at the end of the opening swing. Both cushion angles are offered with or without hold open, so you can spec, for example, 105 degree cushion with no hold open on a door that must not stand open.
5) How heavy a door can this Dorma concealed closer handle, and what if mine is heavier?
The RTS06 package is rated to 250 lbs of door weight, which covers most wood entrance leaves. If you are near or over that, look at a heavy duty overhead concealed unit instead, such as the Sargent 268 with a cast iron body or the Sargent 278 with an exposed arm, both Grade 1 heavy duty.
6) What else could I use instead of the Dorma RTS06 for a center hung overhead concealed closer?
Two close center hung alternatives: the Norton Rixson 608 Series and the 700 Series, both center hung overhead concealed and rated at 200 lb doors, both standard duty. If your door is offset hung rather than center hung, the Rixson 0608 Series is the offset hung version for aluminum doors up to 200 lbs. For a heavier double acting opening at the same 250 lb capacity, the Rixson 73 Series is center hung double acting, Grade 1 heavy duty, and ships with a cover plate.
7) Can the RTS06 handle a 4 foot wide interior door?
Yes, with the right spring. SZ4 is the strongest closing force offered and covers 3'-6" to 4'-0" interior doors. Below that, SZ3 handles 3'-0" to 3'-6" interior. SZ2 is a light opening force spring for lighter interior applications. Door weight still has to stay within the 250 lb rating.
8) Can I order a CRL Jackson concealed closer as a drop-in replacement for an RTS06?
Treat that carefully. The CRL Jackson 20-101M units - the regular duty 105 degree and 90 degree no hold-open bodies, the heavy duty 105 degree no hold-open, and the adjustable spring power 105 degree no hold-open - are sold as closer body only, so no mounting hardware, spindle or frame prep parts come with them. The RTS06 is available as a complete package, and it can be ordered with the 8563 frame cover plate added. If you are replacing a whole assembly rather than swapping a failed body into existing prep, a complete package is the closer match.
9) My door is offset hung, not center hung - what concealed closer should I use instead of the RTS06?
Use the Norton Rixson 0608 Series, an offset hung overhead concealed closer for aluminum doors up to 200 lbs, standard duty. The RTS06 is a center hung side load unit, so the pivot geometry will not transfer to an offset hung opening. Confirm your door weight against the 0608's 200 lb figure, since the RTS06 covers doors to 250 lbs.
10) I need the door to swing a full 180 degrees - can the RTS06 do that, or is there a better closer?
The RTS06 is offered with a 90 degree or 105 degree cushion setting. If the opening has to swing wider, look at the Sargent 269, a heavy duty Grade 1 overhead concealed closer with 180 degree opening capability.
11) What is the difference between the BFI and BFE spring sizes on the RTS06?
Both are barrier free light opening force springs sized for a 3'-0" door. BFI is the interior door version, BFE the exterior. Exterior leaves need more force to overcome wind and stack pressure, so the two are not interchangeable even though the door width is the same.
12) Does the RTS06 come with everything needed to install it, or do I need extra parts?
Order it as the Complete Package, which is the standard configuration, and you have the closer package for the wood door and aluminum frame application. The one add on offered is the 8563 frame cover plate, which you select at order time if the head needs to be covered off. Decide that before you order, since it is a package option rather than a loose accessory added later.
13) Is a concealed closer like the RTS06 a good fix for entrances where surface closers keep getting vandalized?
That is one of the main reasons it gets specified. With the closer body hidden in the frame head there is nothing exposed on the door face to pry, hang on, or tamper with, which is why it gets used as a replacement on problem entrances where surface applied units keep failing. It also keeps the opening clean architecturally when a surface closer would interfere with the design.
14) Is there a lighter-duty center hung concealed closer if my door is under 200 lbs?
Yes. The Norton Rixson 608 Series and the Norton Rixson 700 Series are both center hung overhead concealed closers rated for 200 lb doors at standard duty. The RTS06 is rated to 250 lbs, so on a lighter aluminum or wood leaf either Rixson standard duty unit covers the weight. Note the RTS06 is non-handed and works single or double acting, and it is offered with a 90 degree or 105 degree cushion and with or without hold open.
15) What Grade 1 alternatives are there to the Dorma RTS06 for a high-traffic entrance?
Three Sargent units carry Grade 1 heavy duty ratings: the 268 with a cast iron body, the 269 with 180 degree opening capability, and the 278 with an exposed arm. The Norton Rixson 73 Series is also Grade 1 heavy duty and is center hung double acting at 250 lbs. The RTS06 is a commercial non-handed center hung closer for 250 lb doors, single or double acting.
16) I need a hold-open concealed closer - which of these offer it?
The RTS06 can be ordered with hold open or without, in either the 90 degree or 105 degree cushion. Among the CRL Jackson concealed bodies, the 20-101M-01, 20-101M-03, 20-101M-09 and 20-101M-17 are all no hold-open, so none of those will hold the leaf open. Specify the hold open option on the RTS06 if the opening needs it.
17) Which concealed closer should I pick if I want one spring power that covers a range of door widths instead of specifying a size?
The CRL Jackson 20-101M-17 is an adjustable spring power overhead concealed closer body, 105 degree no hold-open, so one unit covers a spread rather than committing to a fixed size. The RTS06 instead is ordered by spring size: BFI and BFE barrier free light opening force for 3'-0" interior and exterior doors, SZ2 light opening force, SZ3 for 3'-0" to 3'-6" interior and 2'-6" to 3'-0" exterior, and SZ4 for 3'-6" to 4'-0" interior and 3'-0" to 3'-6" exterior. Measure the leaf before ordering the RTS06.
18) If the closer arm can be exposed rather than fully concealed, is there another option?
The Sargent 278 is an overhead concealed closer with an exposed arm, Grade 1 heavy duty. The RTS06 is a fully concealed unit intended for openings where surface applied hardware would interfere with the architectural design, and it is also used as a replacement where surface closers have been vandalized.
