Product Identity
The Simplex 6204-86 is a gray mechanical pushbutton combination lock designed for exterior access without keys. It suits commercial or residential doors where a single shared code replaces physical credentials and battery maintenance is unwanted.

Questions about this item
How does the 70mm backset affect where I drill the hole in my door?
The 70mm backset means you drill the bore hole centre 70mm from the door edge. This matches the common 2-3/4 inch standard used on many commercial and residential doors.
What does the 3-hour UL/ULC fire rating cover for this lock?
The lock carries a 3-hour UL/ULC fire rating for "A" labeled doors, meaning it can remain secure and operable during a three-hour fire test on a rated door assembly.
What door thicknesses does the 6204-86 fit without extra parts?
It fits doors from 35mm to 57mm thick (1-3/8 to 2-1/4 inches) using the supplied components, with a unified interior trim plate and fixed interior knob included.
