958 Series – Key in Lever Storeroom Escape Options

This lockset from Lockwood’s 958 Series is built for storeroom escape functionality, making it ideal for commercial, educational, and institutional environments. The 6MK (6-pin master keyed) configuration allows individual doors to be operated by unique keys while maintaining a master key that opens all locks in the system. The outside lever remains rigid, requiring a key to retract the latch, while the inside lever always allows free egress, ensuring compliance with emergency exit standards.
