What Are the Different Types of Commercial Door Locks For a Business?
Commercial spaces need commercial door locks to protect their business from theft, vandalism, and weather. The market offers a wide range of business door locks available for purchase, so it is crucial to pick the best one for your security needs. We put together a guide on the different lock types and grades to help you select the lock best suited for your needs.
Commercial Lock Types
Cylindrical Lever Locks
Bored cylindrical lever locks are fitted in the door by drilling two circular holes. Cylindrical lever locksets are reliable for high-traffic, heavy-abuse applications. This type of lock is easy to install, vandal resistant and has a reliable performance life. They are the most often used commercial lock type and come with various features, functions, grades, styles, and finishes.
Mortise locks are the strongest and most versatile lock type, engineered to withstand constant use and abuse. These locks are more expensive than cylindrical locks but are more durable and longer lasting. Mortise lock installation, on the other hand, is usually not a do-it-yourself project. A pocket on the edge of a door is required for mortise locks, into which the lock case is inserted. A commercial locksmith is generally called in to make a precise cutting of the pocket.
Deadbolt locks have a bolt that must be unlocked with a key or thumb turn. When used with a cylindrical lockset, deadbolt locks add an extra layer of security against break-ins. This type of lock is secure since it is not spring-loaded and can withstand drilling, picking, and bumping. Deadbolts can be used with a door pull and installed on a door with a standard borehole. They are easy to mount and designed to fit all standard doors.
Electronic locks are suitable for doors that require a secure, non-keyed solution. This type of lock uses secure digital codes or biometric identification, therefore eliminating the need for keys. Keypad locks are a kind of electronic lock with a cylinder or key override. Electronic locks require a little more thought in terms of door requirements, so it is advisable to talk to a commercial door locksmith about your alternatives.
Cylindrical Knob Locks
In cylindrical knob locks, the knob turns the lock’s spindle, which in turn rotates the bolt.
This type of lock is available in a variety of functions, albeit less typically utilized in Americans with Disabilities Act (ADA)-compliant establishments as they can be difficult for people with mobility impairments to use. Knob locksets are only advised for entrances that are not subject to ADA regulations.
Commercial Lock Grades
Commercial locks with ANSI/BHMA certification are designated as Grade 1 or Grade 2. The lock grades represent different levels of performance.
ANSI Grade 1
Grade 1 locks are typically intended for commercial applications as they offer the highest level of strength and security. They can survive 800,000 cycles, six door impacts, and a 360-pound load and can withstand 250,000 cycles and a hammer test of 10 door strikes.
ANSI Grade 2
Grade 2 locks are light-duty commercial locks but are not usually sufficient for many commercial buildings. They can withstand 400,000 cycles, four door strikes, a weight of 250 pounds, 150,000 cycles, and a 5-door-strike hammer test.
