Yale 780H-619 Satin Nickel Storeroom Knob Door Lock

Storeroom Knobset Function

The Yale 780H-619 is a heavy-duty storeroom knobset designed for doors where the outside handle remains locked at all times. Entry from the exterior requires a key, while the inside knob always allows free egress. It suits commercial storerooms, utility rooms, and other spaces that need constant exterior security. The lock is ANSI/BHMA Grade 3 certified and carries a 90 minute UL fire rating.

Door Thickness Compatibility

This knobset fits doors ranging from 1-3/8" to 1-3/4" thick with a standard 2-3/8" backset. It is not suitable for thinner interior doors or thicker exterior doors that fall outside this range. Builders working with non-standard door thicknesses should verify measurements before ordering. The lock installs into a 2-1/8" face bore and a 1" edge bore.

Kwikset KW2 Keyway

The cylinder uses a 5-pin brass Kwikset KW2 keyway and is supplied keyed different. This specification determines whether the lock can share keys with existing Kwikset hardware in the building. If the facility uses a different keyway, the cylinders will not be compatible without rekeying. The solid brass cylinder provides standard durability for Grade 3 applications.
