Learn moreFrequently Asked Questions
What is the difference between a commercial cylindrical lock and a mortise lock?
A cylindrical lock uses a bored chassis crossing the door, while a mortise lock uses a larger case installed into a pocket in the door edge. The prep, components and replacement considerations are different.
Are commercial lever locks always cylindrical locks?
No. Commercial lever trim can operate cylindrical, mortise, interconnected and electrified lock bodies. Identifying the chassis behind the lever is part of diagnosis.
What is an interchangeable core lock?
It is compatible lock hardware designed so an authorized control key can remove the keyed core without taking apart the whole lockset. SFIC and LFIC formats must match the host housing.
Do storefront hookbolts belong under commercial lock types?
Yes. Storefront hookbolts are commercial lock hardware, but their narrow-stile door preparation, keeper alignment and cylinder/cam relationship make Storefront Lock Repair the more useful service path for that opening.
