Commercial Lock Solutions: Three Scenarios

Selling the "right" hardware for a commercial or institutional job is dependent first and foremost upon meeting applicable Life Safety and building codes. If doors open to the public, they are generally considered the path of egress and must accommodate egress without prior knowledge. They also must meet ADA requirements. If the opening is fire rated, additional restrictions apply. After all code requirements are understood, we can then begin to think about and discuss what the owner/end-user wants to do with the door.

Photos show the doors before their upgrades. Read the full article to see what solutions were used.

Scenario 1: Non Fire-Rated Opening: A non-fire rated opening was chosen as our first scenario because it is the least complicated installation. A single pair of double inswinging doors provides access to a storage room that is not available to the public. These doors open to a standard sized storage room that meets local and state building and fire codes. Be aware that local codes, which may vary by location, may determine space size.

Scenario 2: Fire Rated Opening: The pair of outswinging doors in this office building is fire rated. For this installation, new hollow metal, 3-hour fire rated doors were purchased and installed. For this interior application, 18 gauge doors were ordered. The occupancy load, more than 50 persons, requires exit devices as the lock mechanism. Fire doors are required to be self closing and positive latching. The doors were ordered with exit device and door closer reinforcement.

Scenario 3: Grade 1, Non-Fire Rated: The pair of outswinging doors in this office building is not fire rated. The door can be hollow metal or wood. Even though the opening is not fire rated, the door hardware must be Grade 1. For this application, the occupant load is 50 or less, which permits the use of a mortise lock. If the occupancy load was more than 50, the locking mechanism must be exit devices. If the occupancy load is more than 15 and less than 50, both doors must be active, which means each door must have an operable locking mechanism and a fixed position strike plate. If the occupancy load is 15 or less, there can be one active and one inactive door. The inactive door can be equipped with the strike plate.
