The Master Lock No. 3UP can be pinned to an existing Master Lock key in minutes, which makes it a practical choice for keyed-alike setups where every lock on a property needs to open with the same key. A 1-9/16" (40mm) laminated steel body carries a short 3/4" shackle that keeps the shackle opening tight against the hasp.

• Pins to your own key on site in minutes - no factory keying order
• Uses the Master Lock No. 376 Universal Pin Keying Tool (sold separately)
• 1-9/16" (40mm) wide laminated steel body for superior strength
