Overview
About this product
This storeroom mortise lock pairs Corbin Russwin's Newport lever with the A wrought rose, which is what the NSA suffix in ML2057 NSA stands for. The ANSI F07 function suits supply rooms, electrical closets and other doors that should be locked whenever they are closed.
Built to ANSI/BHMA Grade 1, the lock is UL10c listed with a 3 hour fire rating. It is made for 1-3/4 inch doors at a 2-3/4 inch backset, throws the latch 3/4 inch, and is listed as ADA compliant under A117.1.
What the function does
From outside, the latchbolt opens only by key because the outside lever never turns. From inside, the lever always retracts the latchbolt. The auxiliary latch deadlocks the latchbolt.
Highlights
- Outside lever always rigid: key required from outside
- Inside lever always free
- Door is locked whenever it closes
- Newport (NS) lever on A wrought rose trim
- Grade 1 lockbody with UL10c listing and 3 hour fire rating
- 2-3/4 inch backset for 1-3/4 inch doors

How it works
Storeroom function, ANSI F07
The outside lever is always locked and only a key opens it. The inside lever is always free, so nobody gets locked in. Common on storage, mechanical and janitor rooms.
