Drive Assembly for 3001 Series

The Simplex 3020-19 is a left-hand drive assembly built for the 3001 series mechanical pushbutton lock. It suits installers replacing the internal drive mechanism on an existing lock body. The lock itself is not included and must be sourced separately.

Satin Chrome Finish and 31/32 Inch Backset

The unit carries a satin chrome finish and a fixed 31/32 inch backset, matching doors prepared to that specification. Its left-hand orientation determines the handing of the lever or knob, so the door swing must correspond. The assembly mounts inside the lock chassis using the standard 3001 series mounting pattern.

Supplied as a Complete Drive Unit

The box contains the complete drive assembly ready for installation into a compatible 3001 lock housing. No additional drive components are required, though the separate lock body, trim and any cylinders must be provided by the installer. Keying is keyed different, so cylinders will not match other locks unless rekeyed.

Questions about this item

What backset does the Simplex 3020-19 drive assembly use and what door thickness does it suit?

The assembly is built for a 31/32 inch backset, which is 25 mm, matching the standard prep for the 3001 series lock body.

Which door hand and lock series does this left-hand drive assembly fit?

It is a left-hand drive unit made exclusively for the Simplex 3001 series mechanical pushbutton lock.

How is the 3020-19 drive assembly installed and what common error should be avoided?

Remove the existing lock chassis, slide the drive assembly into the 31/32 inch backset bore, secure with the supplied screws, then reattach the lock; the frequent mistake is fitting a right-hand unit on a left-hand door.
