Dormakaba 204022-000-01 – Frequently Asked Questions
1) What does the Simplex 204022-000-01 latch extension assembly actually do?
It extends the backset on a Simplex mechanical pushbutton lock. Ordered in one of two sizes, it converts the lock to a 3-3/4 inch (95mm) backset or to a 5 inch (130mm) backset. It is a replacement/conversion part for the lock itself, not a complete lockset, so you are adding it to an existing Simplex mechanical lock.
2) Which backset should I order for a glass-front or wide-stile aluminum door?
Two sizes are offered: one converts the Simplex mechanical lock to a 3-3/4 inch (95mm) backset, the other to 5 inch (130mm). Measure from the door edge to the center of the existing cross-bore or the center of the lock prep on your door and match that number. On wide stile and glass front doors the lock body sits further in from the edge, which is exactly why the 5 inch version exists. Getting this wrong means the lock will not line up with the existing holes.
3) I have a standard 2-3/4 inch backset door. Do I need this extension assembly?
No. The 204022-000-01 assembly only exists to push a Simplex mechanical lock out to a 3-3/4 inch (95mm) or 5 inch (130mm) backset. If your door is prepped at one of the two common backsets, 2-3/8 or 2-3/4 inches, the standard Simplex lock works as-is and adding this part would put the lock in the wrong position.
4) Will this latch extension work on an electronic Simplex lock?
No. The 204022-000-01 extension assembly is for Simplex mechanical pushbutton locks. It is a mechanical lock part, so if you are working on a battery-powered or electronic Kaba/dormakaba unit, this is not the piece you need.
5) Do I get a new latch with the 204022-000-01, or just the extension hardware?
It is a mounting assembly, sold as a replacement part for a Simplex mechanical lock. Order it to change the backset on a lock you already have in hand or already installed. Plan the job around keeping the existing Simplex lock body and trim.
6) Is this a residential part or rated for commercial door traffic?
Commercial. The Simplex latch extension assembly is catalogued as commercial door hardware, which is where Simplex pushbutton locks are normally used: offices, schools, storage and equipment rooms, and multi-family common doors.
