Dormakaba 201821-05-01 – Frequently Asked Questions

1) What is an ASA roller strike and when would I use one instead of a flat strike plate?
An ASA roller strike replaces the fixed lip of a standard strike with a roller that the latch rides over as the door closes. The Dormakaba 201821-05-01 uses that roller to cut friction during latch engagement, which makes closing quieter and eases wear on the latch itself. It's the choice on high-traffic commercial openings where a latch is slamming a fixed strike lip thousands of times. A flat deadbolt strike, like the Deltana SP2753 or the Emtek 83223 square-corner plate, is a different animal entirely, those catch a deadbolt, not a spring latch.
2) Will the Dormakaba 201821-05-01 fit a frame already prepped for a standard ASA strike?
Yes. The 201821-05-01 is built to ASA strike dimensions, so it drops into a frame cut for the standard commercial ASA pattern used with mortise and cylindrical lock hardware. If your existing strike is ASA (the tall rectangular plate with the rounded or square-cornered lip, the common commercial prep), no frame modification is needed. If the frame is prepped for a small residential T-strike, this is not the part.
3) I need a strike for a deadbolt, is this the right part?
No. The 201821-05-01 is a roller strike for a spring latch, the roller is there for a latch that rides in and out on every close. A deadbolt throws straight into a plain rectangular opening and needs a deadbolt strike instead: the Deltana SP2753 at 2-3/4 by 1-1/4 inches in steel, or the Emtek 83223 square-corner deadbolt plate. If you need a dust box behind the bolt, the Kwikset 81231-001 metal strike dust box covers that.
4) Is there another ASA-pattern strike besides the Dormakaba 201821-05-01?
Yes. The Codelocks CDL-ASA is also an ASA strike plate, supplied in a stainless steel finish. The Dormakaba 201821-05-01 is an ASA roller strike in Antique Brass, so the roller mechanism and the brass appearance are what set it apart. If you are matching existing Antique Brass Dormakaba trim, stay with the 201821-05-01; if finish is not a concern and you only need the ASA cutout covered, the stainless CDL-ASA is the alternative.
5) Can I use a deadbolt strike plate in place of the Dormakaba 201821-05-01?
No. The 201821-05-01 is an ASA roller strike for a latch, where the roller reduces friction as the latchbolt engages. Deadbolt strike plates such as the Deltana SP2753 (2-3/4 inch x 1-1/4 inch steel) and the Emtek 83223 standard deadbolt strike plate with square corners are made for a bolt that is thrown by a key or thumbturn, not for a spring latch riding across a roller. They are different preps and different functions - order the deadbolt plate for the deadbolt bore and the ASA roller strike for the latch.
6) Is this a genuine Dormakaba replacement part for their mechanical locks?
It is. The 201821-05-01 is catalogued by Dormakaba as a replacement strike for their mechanical lock hardware, so it mates with the matching Dormakaba latch without the fit guesswork you get from a generic aftermarket plate.
7) What finish does the Dormakaba 201821-05-01 roller strike come in, and can I get it in another finish?
Antique Brass only, factory applied, and that's the single configuration this strike is offered in. It's meant to coordinate with Antique Brass Dormakaba lock trim on the same opening. If your building is standardized on satin chrome or stainless, the Codelocks ASA strike plate is an ASA-pattern option in a stainless steel finish.
8) Is this strike rated for commercial traffic or is it a residential part?
Commercial. Dormakaba lists the 201821-05-01 as commercial-grade hardware, and the roller design exists specifically to survive repeated cycling on office, school, healthcare, retail, and multi-tenant openings. Residential strike parts, the Kwikset 81640 strike box or the KWI-80318 full round adjustable strike for example, are built for a different duty level and a different prep.
9) Can I use this ASA roller strike to standardize strikes across a whole building?
That's a reasonable use for it. Because it follows the ASA pattern, any opening in the building already running a standard commercial ASA frame prep takes the same part number, so a facility can carry one strike SKU for mortise and cylindrical lock openings alike. The constraint is finish: it comes in Antique Brass, so it suits buildings whose lock trim is already Antique Brass.
10) What should I use if the frame prep is off and I need adjustment rather than a fixed ASA strike?
The Dormakaba 201821-05-01 is a fixed ASA-pattern roller strike, so it relies on the frame being prepped to standard ASA dimensions. Where the alignment has to be dialed in, Kwikset offers adjustable options: the KWI-80318 full round adjustable strike and the KWI-81825 6-way adjustable deadlatch, both catalogued for deadbolt strike duty. Note the change in function - those are deadbolt-side parts, not a roller strike, so they suit a different opening rather than serving as a drop-in for the Dormakaba.
11) Do I need a strike box behind the Dormakaba 201821-05-01, and what are my options?
The 201821-05-01 is the ASA roller strike plate itself, not a boxed assembly. If your frame needs a separate dust box or strike box, Kwikset supplies the 81231-001 metal strike dust box and the 81640 strike box, both catalogued for deadbolt strike use. Confirm the box matches your frame cutout and bolt or latch projection before ordering, since these are sized for deadbolt prep rather than the ASA pattern.
12) For a commercial office or school opening, which strike is the closer fit - the Dormakaba 201821-05-01 or the Kwikset strike parts?
The Dormakaba 201821-05-01 is designated a commercial part and is an ASA roller strike intended for mechanical lock hardware in settings such as offices, schools, healthcare and multi-tenant residential. The Kwikset parts in the same family - the 80318 full round adjustable strike and the 81640 strike box - are deadbolt strike components, so they address the deadbolt rather than the latch prep. For standardizing ASA latch strikes across a facility, the 201821-05-01 is the item that matches that prep.
