Dormakaba 91015 605 – Frequently Asked Questions

1) What size is the Dormakaba 91015 T-strike plate, and will it drop into my existing frame cutout?
The Dormakaba 91015 full lip T-strike measures 1-5/8 x 2-1/4 inches with a 1-1/8 inch lip length and square corners. If the strike mortise already in your frame is cut to those dimensions with square corners, it drops straight in. A frame prepped with radius (round) corners will show gaps at the corners and needs to be filed to square or fitted with a round-corner strike instead.
2) My frame is prepped for an ASA strike, not a T-strike. Can I use the 91015?
No. An ASA prep is a taller cutout (commonly 4-7/8 inches) and the 91015 is a 1-5/8 x 2-1/4 inch T-strike, so it will not cover it. For an ASA-prepped frame, use an ASA-format plate such as the Codelocks ASA strike plate in stainless steel.
3) Is the Dormakaba 91015 a deadbolt strike, or do I need a different plate for a deadbolt?
The 91015 is a full lip T-strike for latch engagement on commercial mechanical lock assemblies, not a deadbolt strike. For a deadbolt bolt hole, the Deltana SP2753 is a 2-3/4" x 1-1/4" steel deadbolt strike plate, and the Emtek 83223 is a standard deadbolt strike plate with square corners. On a door with both a latchset and a deadbolt you would use the 91015 for the latch and one of those deadbolt plates above it.
4) What strike plate should I use instead of the Dormakaba 91015 when the door is prepped for an ANSI/ASA strike cutout?
The Dormakaba 91015 is a full lip T-strike measuring 1-5/8" x 2-1/4" with a 1-1/8" lip and square corners, so it drops into a T-strike mortise, not the larger ANSI/ASA rectangular prep. For an ASA-style cutout, the Codelocks ASA Strike Plate in stainless steel finish is the strike built for that preparation. Confirm which cutout the frame already has before ordering, since the two preps are not interchangeable without filing or shimming the frame.
5) The frame hole and the bolt do not quite line up. Is there an adjustable strike I can use rather than the Dormakaba 91015?
The 91015 is a fixed full lip T-strike with a 1-1/8" lip and square corners, so it offers no adjustment; the frame prep has to match. If you need to take up misalignment, the Kwikset 80318 is a full round adjustable strike and the Kwikset 81825 is a 6 way adjustable deadlatch, both catalogued for deadbolt strike duty. Those give you movement at the strike instead of reworking the frame.
6) What finishes does the Dormakaba 91015 strike plate come in?
Five finishes: 605 bright brass, 606 satin brass, 612 satin bronze, 613 oil rubbed bronze, and 630 satin stainless. For fleet work, match the BHMA number on the lock you are servicing rather than the finish name, since 605 and 606 both read as brass but differ in gloss, and 612 and 613 are both bronze with different tones.
7) What does the full lip on a T-strike actually do?
The lip is the curved tongue that extends past the frame face and guides the latch in as the door closes, and it also protects the jamb from the latch bolt scraping it. On the 91015 the lip runs 1-1/8 inches, and the full lip covers the frame cutout completely so no raw edge shows. On a frame with deep stop-to-face distance a longer lip is needed; a lip that is too long protrudes into the opening and can catch clothing or carts.
8) Is the 91015 strike rated for commercial traffic or is it a residential part?
Commercial. The 91015 is specified for commercial mechanical lock applications, the kind of use you see in office buildings, schools, healthcare, retail, warehouses, multi-tenant residential and municipal facilities. Residential deadbolt strikes such as the Kwikset 81640 strike box or the Kwikset 80318 full round adjustable strike are built for a different class of lock and are not substitutes here.
9) My door latch is not catching. Will swapping the strike plate fix it?
Sometimes. A worn or misaligned lip is a common cause, and a fresh full lip T-strike like the 91015 restores clean latch engagement since the full lip covers the cutout and guides the bolt in. If the misalignment is vertical or the gap between door and frame has changed, you need adjustment in the strike position or hinges instead, or an adjustable strike such as the Kwikset 81825 six-way adjustable deadlatch on applications that accept one.
10) Does ordering the Dormakaba 91015 also get me the dust box behind the frame?
No. The 91015 is the visible full lip T-strike plate itself, sized 1-5/8" x 2-1/4", and does not serve as the mortise pocket liner. If you also need the box behind the plate, the Kwikset 81231-001 is a metal strike dust box and the Kwikset 81640 is a strike box. Those are separate items and do not replace a strike plate.
11) For matching existing hardware across a building, does the Dormakaba 91015 or the Codelocks ASA strike give me more finish choices?
The Dormakaba 91015 is stocked in five finishes: 605 bright brass, 606 satin brass, 612 satin bronze, 613 oil rubbed bronze, and 630 satin stainless, which lets you match brass, bronze, or stainless trim already on the doors. The Codelocks ASA Strike Plate is offered in a stainless steel finish. If your standard is oil rubbed bronze or brass, the 91015 finish range is the one that covers it.
12) Emtek 83223 also has square corners. Can I use it in place of the Dormakaba 91015?
Square corners alone do not make them interchangeable. The Emtek 83223 is a standard deadbolt strike plate, so its opening is cut for a deadbolt throw, while the Dormakaba 91015 is a full lip T-strike with a 1-1/8" lip that covers the door edge cutout and guides a latch bolt. Use the 91015 where a latching mechanical lockset is engaging the frame.
13) Is this a genuine Dormakaba part or an aftermarket strike?
It is a genuine Dormakaba replacement component, model 91015, from the Dorma parts and accessories line. For maintenance teams standardizing on Dormakaba locksets, that matters because the plate is cut to the same tolerances as the original prep rather than approximated.
