Schlage ND53PD Grade 1 Entrance Lock, Standard Cylinder, Non-Handed

Schlage ND53PD Grade 1 Cylindrical Entrance Lock

Control outside access while keeping the inside lever free for immediate egress with the Schlage ND53PD entrance lock. This commercial cylindrical lever lock combines a standard cylinder, a non-handed design, and an inside push/turn button for everyday entrance security. It fits the common ANSI 161 cylindrical door preparation for new construction and retrofit applications.

The ND Series exceeds ANSI/BHMA Grade 1 operational and security standards. Series testing includes 3,100 in-lb of abusive lever torque, more than 2-1/2 times the Grade 1 requirement, and offset lever pulls up to 1,600 lb. After 16 million cycles, the series demonstrates nearly zero lever droop or wobble.

Function:

• Unlocked: Either lever retracts the deadlatch.
• Push-button locking: Press the inside button to make the outside lever inoperative. Using the outside key or turning the inside lever retracts the latch and releases the button, unlocking the outside lever.
• Push-and-turn locking: Push and turn the inside button to keep the outside lever locked. The outside key or inside lever retracts the latch without unlocking the outside lever. Return the button to its starting position to allow button release and unlocking by key or inside lever.
• Inside operation: The inside lever is always free for immediate egress. The outside key does not lock the outside lever.

Lockout caution: Leaving without fully releasing the push/turn button can leave the outside lever locked.
