This is a new in open box LSDA MLF Series Grade 1 Mortise Lock. Model: “MLF48SA26D Storeroom W/DBT” I bought a pallet of NOS (New Old Stock) Locksmith related items from a school district near Ft. Worth, TX. See the photos for more info. The item in the photos is the item you will receive. I have, or will have, other commercial locksmith items that came from the school district listed. Thanks for looking!
