The lock ships with a blue weatherproof cover that shields the body from rain, moisture, and temperature extremes. The shackle is hardened steel, measuring 2 inches in length and 3\/8 inches in diameter, providing a longer reach than a standard shackle for use on larger hasps, chains, and gate hardware. Licensed HVAC, plumbing, and electrical contractors frequently use locks of this type to secure outdoor equipment enclosures, gas meter access panels, and electrical disconnects.\u003c\/p\u003e\u003cp\u003eThis padlock is suited for exterior installations where weather protection is required without sacrificing lock integrity. The laminated steel body construction resists corrosion and impact, making it appropriate for both residential and light commercial service environments. The long shackle design accommodates thicker hasp hardware and chain links common in mechanical equipment rooms and rooftop unit enclosures. It is sold in a package quantity of 4 units per carton, making it practical for fleet service trucks and service contracts requiring multiple secured locations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBlue weatherproof cover protects lock body from rain, moisture, and extreme temperatures\u003c\/li\u003e\n\u003cli\u003eHardened steel shackle at 2 inches length for extended reach on large hasps and chains\u003c\/li\u003e\n\u003cli\u003e3\/8 inches shackle diameter for compatibility with standard chain and hasp hardware\u003c\/li\u003e\n\u003cli\u003eLaminated steel body construction for impact and corrosion resistance\u003c\/li\u003e\n\u003cli\u003eKeyed to Master Lock Key Blank K1BOX or Ilco Blank M1 TV 320-952 for easy rekeying sourcing\u003c\/li\u003e\n\u003cli\u003eSold 4 units per carton for multi-location service applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eKeyed to Master Lock Key Blank K1BOX or Ilco Blank M1 TV 320-952.

Before securing electrical disconnects or gas meter enclosures, verify that all power is off and gas is shut off per local code requirements. Ensure the weatherproof cover is fully seated after each use to maintain protection against moisture intrusion.
