Sargent 68-3931 – Frequently Asked Questions

1) Is the Sargent 68-3931 chassis assembly left hand or right hand?
The 68-3931 is the left-hand version. Handing is built into the chassis, so it will only work correctly on a left-handed opening. If the door you are servicing is right-handed, this part is the wrong one and you need the right-hand chassis assembly instead. Determine handing from the outside of the door: standing on the side the lock's keyed face is on, if the hinges are on your left, it's left hand.
2) Can I rebuild a Sargent lock with this chassis instead of replacing the whole lockset?
That's exactly what the 68-3931 is for. It is a genuine Sargent replacement chassis assembly, so you can do a component-level repair on an existing PP, PR, SP or 12-8700 lock and keep the existing lock body, trim and door prep in place rather than buying a complete lockset and re-prepping the opening.
3) Is the 68-3931 an aftermarket chassis or a genuine Sargent part?
Genuine Sargent, built to the original design specifications for the PP, PR, SP and 12-8700 chassis. For a distributor or institutional buyer who has to match an OEM part number on a spec or a work order, the identifier to quote is Sargent 68-3931.
4) Does the Sargent 68-3931 come with a cylinder, trim or lever?
No. The 68-3931 is the chassis assembly only. Cylinders, levers, roses and escutcheons are separate items, so if those parts on the lock you're servicing are worn or you're changing keyway, order them alongside this chassis.
5) Is the Sargent 68-3931 suitable for a high-traffic commercial building, or is it a residential part?
It's a commercial part. The 68-3931 is graded for commercial door hardware duty and is used in offices, schools, hospitals, retail, industrial and warehouse space, multi-tenant residential buildings and government facilities. For a property manager with Sargent hardware across a portfolio, it is the correct service part for high-use openings.
