Falcon A7806-LR – Frequently Asked Questions

1) What is the Falcon A7806-LR and what does it replace?
It's the mortise lock case for Falcon MA551 series locks, built for left hand reverse (LHR) openings. You buy it to rebuild an existing MA551 in the door rather than replacing the whole lockset, trim and prep. It is a genuine Falcon part, so it drops back into the same mortise pocket the original case came out of.
2) Is the armor front included with the A7806-LR lock case?
No. The armor front is not supplied with this case. You either reuse the armor front off the lock you're servicing or source one separately to suit the door. Factor that in before scheduling the install, because the case alone will not finish the opening.
3) My MA551 is on a left hand reverse door. Is this the right lock case?
Yes, the A7806-LR is the left hand reverse case. LHR means the hinges are on the left as you face the door and the door swings toward you (outswing). If you're standing outside the opening and the door pulls toward you with hinges on your left, this is the handing you want. A right hand or right hand reverse opening needs the corresponding case instead, not this one.
4) Will this Falcon lock case fit a mortise lock other than an MA551?
No. The A7806-LR case is built for the Falcon MA551 series only. It is not a universal mortise case, so it will not serve as a substitute in another Falcon mortise family or in a Corbin, Sargent or Schlage mortise lock. Confirm the lock in the door is an MA551 before ordering.
5) Is the A7806-LR heavy enough for a high-traffic commercial door?
It's classified as commercial hardware, not residential, and is intended for high-use commercial openings such as offices, schools, hospitals, retail, warehouses, multi-tenant residential and government buildings. For a property manager standardizing on Falcon MA551 locks across a building, this is the service part for those doors.
6) Do I have to rekey or change cylinders when I swap in this MA551 lock case?
The A7806-LR is the mechanical case only. Trim, levers, cylinder and armor front are separate items, so the existing cylinder and keying come across with the rest of the hardware when you transfer them into the new case. Nothing about the case forces a keying change.
7) Can I just order one lock case and flip it for a right hand door?
No. This case is handed and built exclusively for left hand reverse operation, so it cannot be reversed in the field to serve a right hand opening. If you're stocking spares for a mixed building, order by the handing of each door rather than buying one case for all of them.
