Dormakaba 88973 605 – Frequently Asked Questions

1) What size is the Dormakaba 88973 T-strike and will it drop into my existing frame cutout?
The 88973 T-strike measures 1-1/8 by 2-3/4 inches with a 1-1/8 inch lip length and square corners. It drops in flush on a frame already mortised for a T-strike of that size, with no filing or re-prep. If your existing plate has radius corners or a different face size, the cutout won't match and you'd be patching the frame.
2) My door is rubbing and won't latch cleanly. Will a new 88973 strike fix it, or do I need an adjustable strike?
A fresh 88973 restores a worn or bent lip and clean latch engagement, but it is a fixed-dimension plate at 1-1/8 by 2-3/4 inches with a 1-1/8 inch lip, so it will not take up alignment error from a sagged door or shifted frame. If you need to chase misalignment, an adjustable strike like the Kwikset KWI-80318 full round adjustable strike or the Kwikset 81825 six-way adjustable deadlatch is the tool for that, though those are deadbolt-strike style parts rather than a Dormakaba T-strike.
3) What is the difference between the Dormakaba 88973 T-strike and a deadbolt strike plate like the Emtek 83223?
The Dormakaba 88973 is a T-strike measuring 1-1/8 in. x 2-3/4 in. with a 1-1/8 in. lip length and a square corner, built to guide a latch bolt on Dormakaba mechanical lock applications. The Emtek 83223 is a standard deadbolt strike plate with square corners, so it serves a deadbolt bolt rather than a latch. Both share the square corner profile, but a deadbolt strike has no lip to guide a spring latch as the door closes, so it is not a functional stand-in for the 88973 on a latching lockset.
4) Is the Codelocks ASA strike plate an alternative to the Dormakaba 88973?
They are different strike formats. The Dormakaba 88973 is a T-strike, 1-1/8 in. x 2-3/4 in. with a 1-1/8 in. lip and square corner, matched to compatible Dormakaba mechanical lock preparations. The Codelocks ASA strike plate is an ASA-format strike in a stainless steel finish, which uses the larger ASA frame cutout rather than the narrow T-strike mortise. Choose by the existing frame prep: a frame cut for a T-strike takes the 88973, while a frame cut for ASA takes the ASA plate.
5) What does the 1-1/8 inch lip length do, and how do I know it's the right lip for my frame?
The lip is the curved tab that projects out of the frame and guides the latch in, and on the 88973 it measures 1-1/8 inches. Lip length has to suit how far the door face sits from the frame rabbet: too short and the latch drags on the frame edge, too long and the lip sticks past the jamb where it can catch. Measure the existing plate's lip from the face of the strike to the tip before ordering.
6) What finishes does the Dormakaba 88973 strike come in so I can match the rest of my hardware?
Five finishes: 605 bright brass, 606 satin brass, 612 satin bronze, 613 oil rubbed bronze, and 630 satin stainless. If you're standardizing a building, 630 satin stainless is the usual match for commercial lever and exit hardware, while 613 oil rubbed bronze suits darker decorative sets.
7) Is the 88973 a genuine Dormakaba part or an aftermarket copy?
It's the Dormakaba replacement part, model 88973, carried as an OEM parts and accessories item for Dormakaba mechanical locks. That matters on a strike because the T-shape and lip have to match the latch geometry of the lockset already in the door.
8) Does the 88973 come with a dust box or strike box behind it?
The 88973 is the strike plate itself. If the frame cavity needs a box behind the latch pocket, that's a separate item, for example the Kwikset 81640 strike box or the Kwikset 81231-001 metal strike dust box.
9) What's the difference between a T-strike like this and an ASA strike?
A T-strike has a narrow face, 1-1/8 inches wide here by 2-3/4 inches tall, and suits frames prepped for that small cutout, common on wood frames and older commercial preps. An ASA strike is the larger 1-1/4 by 4-7/8 inch hollow metal frame standard, and for that prep you'd use something like the Codelocks ASA strike plate. The two preps are not interchangeable without frame work.
10) My latch is not lining up with the frame. Should I use the Dormakaba 88973 or an adjustable strike?
The Dormakaba 88973 is a fixed-dimension T-strike at 1-1/8 in. x 2-3/4 in. with a 1-1/8 in. lip length, so it restores the original geometry of a properly prepared frame rather than correcting misalignment. Where the bolt position needs to be shifted, the Kwikset KWI-81825 is a 6 way adjustable deadlatch and the Kwikset KWI-80318 is a full round adjustable strike, both deadbolt strike plate functions. On a Dormakaba mechanical lock with a correctly prepped frame, the 88973 is the direct replacement part.
11) Does the Dormakaba 88973 include a strike box, or do I need one like the Kwikset 81640?
The Dormakaba 88973 is the T-strike plate itself, 1-1/8 in. x 2-3/4 in. with a 1-1/8 in. lip length and square corner, supplied as a genuine Dormakaba replacement part in 605 bright brass, 606 satin brass, 612 satin bronze, 613 oil rubbed bronze and 630 satin stainless. Separate box products such as the Kwikset 81640 strike box and the Kwikset 81231-001 metal strike dust box are dust boxes for deadbolt strike applications and are not part of the 88973's T-strike format.
12) Is this strike plate suitable for a high-traffic commercial door or is it a residential part?
Commercial. Dormakaba lists the 88973 as a commercial replacement component, and the description calls out office buildings, schools, healthcare, retail, industrial, multi-tenant residential, and government facilities. On a high-cycle opening the strike is the part that wears, so replacing it with the OEM item keeps latch engagement consistent.
