Dormakaba 8532 – Frequently Asked Questions

1) What is the Dorma 8532 mounting channel actually for?
The 8532 is a steel header reinforcing channel for overhead concealed closers. An open-throat header doesn't have the metal behind it to carry a concealed closer body, so the channel drops in and gives the closer something solid to bolt to. It is a reinforcement part, not a closer, so you order it alongside the closer, not instead of it.
2) Which Dorma RTS closers does the 8532 channel work with?
The 8532 channel is listed for use with the RTS03, RTS04, RTS27 and RTS28 closers, and Dorma describes it as the reinforcement for installing the RTS88 overhead concealed series in an open-throat header. If your closer is one of those, the channel is the right reinforcement.
3) Do I need the 8532 channel if my header is already reinforced?
No. The channel exists to supply the reinforcement an open-throat header lacks. If the frame was supplied with a factory closer pocket or the header is already reinforced for an overhead concealed closer, you can mount the closer without it. Order the channel when you are cutting a concealed closer into an open-throat header.
4) What size is the Dorma 8532 header channel, and will it fit my header throat?
The channel measures 14 x 4-3/16 x 1-1/2 inches, with the length stated as 14 inches and the height as 4-13/16 inches. Check the clear throat opening of your header against those figures before you cut. The channel has to sit fully inside the header for the closer to bolt through it.
5) Will the Dorma 8532 channel fit a wood frame, or is it steel frames only?
Both. The 8532 is a steel channel intended for steel or wood frames, so it suits a hollow metal opening or a wood-framed one. The channel itself is steel regardless of what it goes into.
6) Can I buy the Dorma 8532 as a replacement part on an existing door?
Yes, it is sold as a replacement part on its own. If you are swapping an RTS03, RTS04, RTS27 or RTS28 closer into an open-throat header that was never reinforced, or replacing a channel that was cut out during a previous job, you can order the 8532 separately from the closer.
7) Is the Dorma 8532 channel a commercial-duty part or a residential one?
Commercial. The 8532 is a door-control part built for commercial openings, which is where overhead concealed RTS closers get used in the first place, storefront and interior entrances carrying real traffic.
8) Does the Dorma 8532 come in different sizes or finishes?
There is one version, model 8532, in steel at 14 x 4-3/16 x 1-1/2 inches. There is nothing to specify on the order beyond the model, and since the channel is concealed inside the header, finish doesn't come into it.
