Master Lock Commercial Combo Pack 4 Pin Steel PK2

SKU CH-E3VV-AMZF3

A pair of keyed-alike steel padlocks with 4-pin cylinders and 1-inch hardened shackles

  • Product typeCommercial Combo Pack
  • Steel body and shackle resist cutting and prying
  • 4-pin cylinder provides pick-resistant security
  • Keyed-alike pair lets one key open both locks
  • 1 in shackle clearance fits standard hasps and chains
  • Laminated steel construction adds strength without extra bulk

Two-pack keyed-alike padlocks

This Master Lock commercial combo pack contains two steel padlocks keyed alike so a single key opens both units. The four-pin cylinders use the Master K1 keyway and are not rekeyable. Each lock has a laminated silver body and a standard steel shackle.

Check shackle clearance and weather needs

Verify that the 3/8 in shackle diameter and 1 in vertical clearance fit the hasp, chain or gate you intend to secure. The 15/16 in horizontal shackle opening must also suit the attachment point. These locks are not weather resistant so they should be used in covered or indoor locations.

Pair with a covered hasp for indoor security

The rectangular steel body measures 1 1/2 in high by 2 in wide by 1 in thick and includes one bumper per lock. The four-pin mechanism provides basic deterrence for cabinets, toolboxes or interior gates. Because the cylinders cannot be rekeyed, the set is not suited for systems that require periodic key changes or master-key expansion.
