Master Lock
The Grade 2 commercial door hardware includes a range of key-in-knob keyways from Schlage, Yale, and others, plus 16 small-format interchangeable core choices. All of the company's door hardware is available with Edge™ key control. The hardware can match most existing key systems when the time comes to expand, replace, or retrofit door locks. The door levers have a clutch feature that resists pry attacks and removable through-bolts. Deadbolts come with a heavy die-cast, anti-pry collar and heavy-duty tie screws.
