For most commercial and institutional openings, specify Grade 1 where the product line offers it, and confirm any fire-rating or ADA listings the opening requires.
How do I find the right Marks USA part number or function?
Marks USA locks are ordered by function (passage, privacy, storeroom, classroom, entrance, and so on), backset, door thickness, lever or knob design, and finish.
