Frequently Asked Questions
What is BEST?
BEST is a dormakaba brand known for interchangeable core (IC) locking and master keying. It is best known for interchangeable-core locks and key systems.
What products does BEST make?
BEST's product range includes small format interchangeable core (SFIC) cylinders, cylindrical and mortise locks, and master key systems.
What is the difference between BEST's cylindrical and mortise locks?
BEST cylindrical locks install through bored holes in the door face and edge, so they are quicker and cheaper to fit and suit interior and medium-duty openings. Its mortise locks seat in a pocket cut into the door edge, are more durable, and can integrate a deadbolt, making them the choice for entrances and high-traffic or high-security doors.
Where is BEST hardware typically used?
BEST hardware is specified for facilities that need flexible rekeying and large master key systems.
Is BEST hardware commercial grade and code compliant?
Yes. BEST manufactures to commercial standards and tests its products to the applicable ANSI/BHMA A156.2 for bored locks and A156.13 for mortise locks. 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 BEST part number or function?
BEST locks are ordered by function (passage, privacy, storeroom, classroom, entrance, and so on), backset, door thickness, lever or knob design, and finish. Identify the function the opening needs first, then match the keyway and finish. Our team can cross-reference an existing BEST number for replacements.
