FAQs

What functions do your cylindrical locks come in? Our collection includes passage, privacy, entrance, storeroom, classroom, office, and intruder functions — covering the most common commercial door applications.

What brands do you carry? We carry cylindrical locks from Best Access Systems, Schlage, and Sargent. Each brand offers a strong lineup for commercial applications, with options across different security levels, lever styles, and finishes.

What is SFIC and do I need it? SFIC stands for Small Format Interchangeable Core. It allows cores to be swapped out quickly without a locksmith, making it ideal for facilities that require frequent rekeying or tight access control — such as schools, healthcare buildings, and multi-tenant offices. Best's 9K series is built around this system.

What's the difference between a storeroom and an entrance function? A storeroom lock is always locked from the outside and can only be unlocked with a key — there's no thumb turn. An entrance function locks from the outside by key but can be toggled to remain unlocked during business hours. Storeroom is the higher-security option.
