Overview
About this product
Corbin Russwin's ML2057 NSA combines the ML2000 Series mortise lockbody with the Newport (NS) lever and A wrought rose in the storeroom function, ANSI F07. Typical uses include storage rooms, IT closets and utility rooms that must stay secured.
Specs include ANSI/BHMA Grade 1, a 3 hour fire rating (UL10c), a 2-3/4 inch backset for 1-3/4 inch doors, and a 3/4 inch latch throw. It is listed as ADA compliant and BAA qualified.
This CL6 version is prepared for a large format interchangeable core (LFIC), so it can be keyed into a facility's interchangeable core system.
What the function does
The latchbolt is retracted by the inside lever or by a key from outside. The outside lever is always rigid and the inside lever is always free. An auxiliary latch deadlocks the latchbolt.

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.

Does the storeroom lock ever stay unlocked?

Can people inside get out?
Yes. The inside lever is always free and retracts the latchbolt.
Will it fit my door?
It is made for 1-3/4 inch thick doors with a 2-3/4 inch backset, using a mortise pocket for the ML2000 Series lockbody.
What fire rating does it carry?
The specifications list a 3 hour fire rating with UL10c listing. Confirm the rating needed on the door's label.
Which finishes are available?
Finish options include 605, 606, 611, 612, 613, 626, 630 and others; choose the one that matches your other hardware.
What does CL6 mean?
CL6 indicates the lock is prepared for a large format interchangeable core, so it works with LFIC keying systems.
