Cal-Royal DSM21 – Frequently Asked Questions

1) What is a Cal-Royal DSM21 door silencer used for on a hollow metal frame?
The DSM21 is a rubber silencer that cushions the door where it meets the frame stop. It absorbs the shock of the door closing, cuts the noise, and puts light tension on the latch or lock so the door doesn't rattle in the frame once it's shut. It's a commercial-duty part, used on office, school, healthcare, retail, industrial, multi-tenant and government openings.
2) Does the Cal-Royal DSM21 meet ANSI/BHMA for door silencers?
Yes. The DSM21 conforms to ANSI/BHMA 156.16 under type number L03011, which is the silencer classification in that auxiliary hardware standard. If your spec or submittal calls out an L030-series silencer, this one answers it.
3) How many Cal-Royal DSM21 silencers come in a bag?
They come 200 to a bag. That's the buy unit, so a facility crew doing a whole building gets enough in one order to do roughly 66 single openings at three per frame or 100 openings if you're only replacing what's missing. There's no smaller pack of the DSM21.
4) How many door silencers do I need per frame, and does that change for a pair of doors?
A single door frame takes three, all on the strike jamb stop. A pair of doors takes four, two on each head half of the stop, because there is no strike jamb to mount them on. Order the DSM21 in bags of 200 and one bag covers a lot of openings either way.
5) Will door silencers stop my commercial door from rattling in the frame?
That's exactly what they're for. The rubber holds slight pressure against the door face when it's latched, which keeps the latchbolt loaded against the strike instead of floating loose in the keeper. That loading is what kills the rattle you get in a drafty corridor or a stairwell. The DSM21 does this and quiets the slam at the same time.
6) Are rubber door silencers the same thing as a door stop or a wall bumper?
No, and they solve different problems. A silencer sits in the frame stop and cushions the door as it closes into the frame. A door stop or wall bumper sits on the floor or wall and stops the door from swinging into something behind it. If your complaint is a slamming, rattling door you want silencers like the DSM21. If it's a lever punching a hole in the drywall, you need a stop, not these.
7) Will silencers interfere with a fire-rated door or a smoke gasket?
Silencers are only used on frames that have no gasketing. If the opening has a smoke seal, sound seal, or perimeter gasketing in the stop, the gasket does the cushioning and the silencer holes get covered, so you leave them out. Order the DSM21 for the plain, ungasketed hollow metal openings in the building and gasket the rest.
8) Can tenants pull the Cal-Royal DSM21 silencers out of the frame?
The DSM21 is built tamper-proof, so it isn't meant to be picked out by hand once seated in the frame hole. That matters in multi-tenant residential, schools, and any corridor where loose hardware walks off. It's the reason to spec these over a stick-on bumper in occupied buildings.
