The dormakaba Simplex 6200 Series is an economical, fully mechanical pushbutton lock providing combination-controlled exterior entry and free egress through an interior knob. It requires no batteries, wiring, keys, cards or software. Available as the 6202 with a 2-3/8" backset or the 6204 with a 2-3/4" backset, the lock features weather-resistant construction and a 3-hour UL/ULC fire-rated cylindrical latch.
Full Product Description
The dormakaba Simplex 6200 Series Mechanical Pushbutton Lock provides reliable keyless access without batteries, electrical wiring, software or electronic credentials. Authorized users enter the programmed combination and rotate the clutch-protected exterior thumbturn to retract the cylindrical latch. From the interior, the fixed knob always provides free egress.
The 6200 Series is available in two primary configurations:
- Simplex 6202: 2-3/8" backset
- Simplex 6204: 2-3/4" backset
Both configurations include a 1/2" throw cylindrical latch with a floating faceplate. Selecting the correct model is essential because the backset is determined by the existing door preparation.
The Simplex 6200 stores one shared mechanical access combination. The code can be changed through the keypad without removing the lock from the door. Because the lock is entirely mechanical, there are no batteries to monitor, power supplies to install or network connections to maintain.
Heavy-duty construction includes an all-metal cast exterior housing, vandal-resistant solid-metal pushbuttons, a force-resistant clutch-protected exterior thumbturn, unified interior trim and a fixed interior knob. The exterior thumbturn’s clutch helps resist forced rotation and abuse.
The lock installs on properly prepared wood or metal doors from 1-3/8" through 2-1/4" thick. It uses an ANSI/ASA 161 cylindrical-lock preparation with two additional through holes. If an existing auxiliary lock interferes with installation, the 6200 can be inverted when the opening and application permit.
The cylindrical latch carries a 3-hour UL/ULC fire rating for “A”-labeled doors, and the lock is weather resistant for indoor or appropriate outdoor applications. The 6200 is factory configured for left-hand doors but can be reversed in the field. Manufacturer specifications
