Schlage A53 Entrance:
The safety and security of your buildings is something we take very seriously. That’s why every Schlage lock and deadbolt undergoes intensive testing to determine its ANSI grade level:
• Cycle tests
• Resistance tests
• Door impact tests
• Warped door tests
• Bolt strength tests
• Cold rolled steel, and machined and threaded hubs prevent loosening of the lockset by bolting the chassis to the door.
• Heavy-duty cast mounting plate with specially tapped holes keeps lockset tight on the door.
• Patented door range adjuster allows quick and easy adjustment for doors ranging from 1 3/8” to 1 7/8” (35 mm to 48 mm) thick
Many Schlage locks are reversible. Hand information is necessary to ensure proper cylinder orientation in keyed functions, and finish of latchbolt and strike for locks that are to be installed on reverse bevel doors. Follow the diagram to correctly determine the hand of the door.
