Inward Door Slip Knife

The Williams Key Inward Door Slip Knife expands the Williams Key system with a purpose built solution for inward opening slam and knob locks.

Created in partnership with The Firefighter Swipe Tool and designed by an FDNY firefighter, this lightweight tool gives first responders a fast, controlled, low damage option when facing compatible latch systems.

It weighs about 1 ounce and fits easily in a pocket, making it an ideal everyday carry addition to your entry setup.

What It Works On

Designed specifically for:

• Slam locks
• Knob locks
• Inward opening apartment entry doors

It does not defeat deadbolts.

This is a latch manipulation tool, not a prying device.
