Dormakaba 54066 626 – Frequently Asked Questions

1) What size is the Dormakaba 54066 T-strike and will it drop into my existing frame cutout?
The 54066 T-strike measures 1-1/8 x 2-3/4 inches with a 1-1/2 inch lip length and square corners. It drops in cleanly where the frame is already mortised square to those dimensions. If your existing strike has radius (rounded) corners, the square-corner 54066 will leave gaps at the corners unless you square the mortise with a chisel.
2) What does the 1-1/2 inch lip length on the 54066 strike do, and how do I know that is the right lip for my frame?
The lip is the curved tab that projects out from the plate to guide the latch in as the door closes. On the 54066 it measures 1-1/2 inches. Lip length has to reach past the frame stop and the door trim so the latch rides up onto it instead of catching the jamb edge, so measure from the centerline of the strike opening to the outside face of the frame or casing. Too short and the latch drags the jamb; too long and the lip sticks into the opening.
3) Can I use a deadbolt strike plate in place of the Dormakaba 54066?
Not interchangeably. The Dormakaba 54066 is a T-strike with a 1-1/2" lip that guides a latchbolt into the frame. Deadbolt strikes such as the Deltana SP2753, listed at 2-3/4" x 1-1/4" in steel, and the Emtek 83223 are built for a bolt that is thrown by key or thumbturn and do not perform the latch-guidance job. For a latch, stay with the 54066.
4) If the frame is prepped for an ASA strike, does the Dormakaba 54066 fit?
No. An ASA prep takes a larger strike with its own cutout, and the Codelocks ASA strike plate in stainless steel is the part for that opening. The Dormakaba 54066 is a T-strike at 1-1/8" x 2-3/4" with a 1-1/2" lip and square corners, sized for a T-strike mortise. Confirm which mortise is in the frame before ordering.
5) What is the closest alternative to the Dormakaba 54066 T-strike for a latch strike with square corners?
The Emtek 83223 is a square-corner strike plate, matching the 54066's square corner profile for frames mortised with square corners. The difference is function: the Emtek 83223 is a deadbolt strike plate, while the Dormakaba 54066 is a T-strike sized 1-1/8" x 2-3/4" with a 1-1/2" lip for latch guidance. If the opening needs the lip to guide a latchbolt, the 54066 is the part; if it is strictly a deadbolt hole, the 83223 suits.
6) My frame prep does not line up with a fixed strike plate. What should I use instead of the Dormakaba 54066?
The Dormakaba 54066 is a fixed-dimension T-strike at 1-1/8" x 2-3/4", so it relies on the frame being mortised to those dimensions. Where the existing prep is off, adjustable strikes give you travel: the Kwikset 80318 is a full round adjustable strike and the Kwikset 81825 is a 6 way adjustable deadlatch. Choose the 54066 when you want a manufacturer-matched fit to the original Dormakaba prep.
7) What finishes does the Dormakaba 54066 strike plate come in so I can match the locks already on my doors?
Six finishes: 605 bright brass, 606 satin brass, 612 satin bronze, 613 oil rubbed bronze, 622 matte black, and 626 satin chrome. Those are standard BHMA finish codes, so match the number stamped or specified on your existing lockset (626 satin chrome is the most common on commercial openings).
8) My latch does not quite line up with the frame. Should I use the 54066 or an adjustable strike?
The 54066 is a fixed-dimension T-strike at 1-1/8 x 2-3/4 inches, so it holds the latch position your frame is already prepped for. It will not correct a misalignment. Where the door has settled and the latch is off center, an adjustable strike such as the Kwikset 80318 full round adjustable strike or the Kwikset 81825 six-way adjustable deadlatch gives you movement to chase the latch.
9) Does the Dormakaba 54066 come with a dust box behind it?
No. The 54066 is the strike plate itself. If the frame pocket needs a box behind the plate to contain the latch cavity, that is ordered separately, for example a Kwikset 81640 strike box or the Kwikset 81231-001 metal strike dust box.
10) I need to standardize strike finishes across a commercial building. Does the Dormakaba 54066 cover more finishes than the alternatives?
The Dormakaba 54066 is offered in 605 bright brass, 606 satin brass, 612 satin bronze, 613 oil rubbed bronze, 622 matte black and 626 satin chrome, so it can be matched to existing lever and lock finishes across a facility. The Codelocks ASA strike plate is a stainless steel finish part. If the goal is one strike part number in several finishes across floors, the 54066 gives you that range in a commercial-rated part.
11) Is the 54066 suitable for high-traffic commercial openings or is it a residential part?
It is classed as a commercial part, a factory Dormakaba replacement from the Dorma parts and accessories line, and it is used in offices, schools, healthcare, retail, warehouses, multi-tenant residential and government buildings. For a residential-grade retrofit on a cylindrical latch you would be looking at something like a Kwikset adjustable strike instead.
