Left Hand Drive Assembly for 3001 Series

This Simplex 3040-19 is a complete left-hand drive assembly built for the 3001 mechanical pushbutton lock series. It features a 1-1/8 inch backset and a satin chrome finish. The lock body itself is sold separately.

Suits installers fitting a left-hand 3001 lock

It will not work on right-hand doors or on lock models outside the 3001 series. Buyers who need a different backset or a complete lock with cylinder should look at other options.

Direct replacement for the original drive unit

Installation involves removing the old assembly and fitting this unit into the prepared door mortise. The most common issue is ordering the wrong hand orientation or backset for the existing door preparation.

Questions about this item

Does the 3040-19 drive assembly require the 3001 series lock body to operate?

Yes, this left-hand drive assembly is designed specifically for the 3001 mechanical pushbutton series and the lock body is sold separately.

Will a 1-1/8 inch backset match my existing door preparation?

The assembly uses a 1-1/8 inch (29mm) backset, so it fits doors prepared to that measurement; verify your current cutout before installing.

How can I confirm the 3040-19 is installed correctly on a left-hand door?

After mounting, the latch should retract smoothly when the pushbutton code is entered and the lever returns positively without binding.
