Questions worth asking
What is the difference between Grade 1 and Grade 2 commercial door hardware?
Grade 1 hardware is designed for heavy-duty, high-traffic applications and undergoes rigorous testing for durability and security. Grade 2 is medium-duty, suitable for lighter commercial use. For most commercial buildings, Grade 1 is recommended.
Can I install commercial door hardware myself?
While some cylindrical levers can be DIY-installed, mortise locks and door closers require professional installation. The precise cutting and alignment needed are best left to experienced technicians.
What is a mortise lock?
A mortise lock is a type of lock that fits into a pocket cut into the edge of the door. It contains both the latch and deadbolt in one unit, offering higher security and durability compared to cylindrical locks.
How do I choose the right hinge for a commercial door?
Consider the door size, weight, and frequency of use. For heavy doors, use ball bearing hinges. The number of hinges required depends on door height: typically three for standard doors, four for taller ones.
What is the importance of door closers in commercial buildings?
Door closers ensure doors close automatically, which is essential for fire safety, energy efficiency, and security. They also comply with ADA requirements for door opening force.
Are commercial door locks compatible with access control systems?
Many commercial locks can be integrated with electronic access control. Look for locks with electrified levers, keypads, or those that accept electronic cylinders. Consult with a security professional for integration.
What finishes are available for commercial door hardware?
Common finishes include satin chrome, oil-rubbed bronze, black, and stainless steel. The finish affects aesthetics and corrosion resistance. Choose a finish that matches your building’s design.
How often should commercial door hardware be maintained?
Routine maintenance should be performed at least twice a year. This includes cleaning, lubricating, and checking for loose parts. High-traffic areas may require more frequent checks.
The verdict
For most commercial applications, the Schlage L-Series Mortise Lock is the best choice due to its superior security and durability. If you prefer a cylindrical lock, the Corbin Russwin AL Series offers excellent performance at a lower cost. For heavy doors, the Hager 4500 Series hinge is indispensable, and the LCN 4040XP door closer ensures compliance.
