Overview
About this product
The Corbin Russwin ML2057 ASA is a storeroom function (F07) mortise lock from the ML2000 Series, fitted with the Armstrong lever (AS) on the A wrought rose. It is built for storerooms, mechanical rooms and janitor closets.
It is rated ANSI/BHMA Grade 1 and carries a fire rating of 3 hours with UL10c listing. The lock fits 1-3/4 inch doors with a 2-3/4 inch backset and has a 3/4 inch latch throw. The specifications list ADA compliance and a 10 year limited warranty on the lockset.
What the function does
