Commercial Locksets

How they fit the door. A cylindrical lock needs only two bored holes, a simpler preparation than a mortise lock, which needs a deep pocket cut in the door edge. The mortise lock's larger case allows more functions, such as a deadbolt worked by the same key. Replacing one type with the other usually means preparing the door again, so match the lock to the door's existing preparation and the lock maker's template.

Except where the adopted code makes a specific exception, a door in a means of egress has to open from the egress side without a key, a tool, or special knowledge or effort, and the IBC generally allows only one releasing motion. See NFPA 101 and IBC Chapter 10. Passage functions, and entrance and office or storeroom functions without a separate deadbolt, leave the inside lever free to retract the latch at all times, which supports that. A function with a separate deadbolt may need another action from inside, so check the exact function. Neither settles whether the opening complies: occupancy, occupant load, the fire rating and any special locking arrangement count too. A lockset is also no substitute where the code calls for panic or fire exit hardware, which the IBC requires on certain doors, such as those serving Group A or E rooms with an occupant load of 50 or more, and Group H occupancies. See rim exit devices. The edition your jurisdiction adopted and your authority having jurisdiction decide.

Only hardware listed and labeled for that fire door assembly, within the door size, rating and configuration its listing covers. A listing may cover only some door sizes, or need a particular latch on a pair of doors. Fire doors generally have to be self-closing or automatic-closing and to latch, though NFPA 80 allows some specific arrangements. A listed lock alone does not make the opening comply: check the lock's listing, its installation instructions and the door's label, and see our UL 10C fire door guide.

Yes, by quote. What comes with a lock varies by model and option, and each product page says whether a cylinder and keys are included. To work with keys you already have, or a master key system, the cylinder has to use a compatible keyway and be keyed to your system, either when the lock is ordered or later by a locksmith.
