Falcon A7806-LH – Frequently Asked Questions

1) Does the Falcon A7806-LH lock case fit a right-hand door?
No. The A7806-LH is factory-configured for left-hand doors only. Handing on a mortise lock case is set internally, so a left-hand case will not operate correctly in a right-hand opening. If your door is right-handed, you need the right-hand version of the MA551 case instead.
2) Is the armor front included with the Falcon A7806-LH?
No, the armor front is not included. You get the lock case only, so plan to reuse the armor front off the lock you are servicing or source one separately before the door goes back together.
3) Which Falcon mortise lock does the A7806-LH case replace?
It is built for the Falcon MA551 mortise lock series. It is a genuine OEM service part for that series, so it drops into an existing MA551 installation rather than being a universal case for any mortise lock.
4) Can I use the A7806-LH case in a mortise lock from another brand, like Schlage L9000 or Sargent 8200?
No. This case is engineered for the Falcon MA551 series only. Mortise case dimensions, hub location and trim spindle geometry vary by manufacturer, so it should not be used to service another brand's mortise lock. Match the case to the MA551 body you are repairing.
5) My MA551 lever stopped retracting the latch. Is replacing the lock case the right fix?
If the failure is inside the case (hub, springs, latch mechanism) then swapping the case is the standard repair, and the A7806-LH is the left-hand case for the MA551. It is sold as a replacement part, so the trim, cylinder and armor front stay with the door and only the case is exchanged. Confirm your door's handing is left-hand before ordering.
6) Do I need to modify the A7806-LH in the field to set the handing?
No field handing work is required. The case ships set up for left-hand operation, which is why the part number carries the LH suffix. That also means it cannot be reversed for the opposite hand.
7) Is this Falcon lock case suitable for a high-traffic commercial door, or is it a residential part?
It is a commercial part. The A7806-LH is from Falcon's commercial mechanical lock line and is intended for high-traffic professional door applications: offices, schools, healthcare, government buildings, retail, warehouses and multi-tenant residential corridors.
