Master Lock 3KALF3186 Laminated Steel Padlock

Product Description

The MASTER LOCK 3KALF3186 is a laminated steel padlock built for general security applications in trade and commercial environments. The body is constructed from reinforced laminated steel layers, providing solid resistance to physical attack. A double locking mechanism engages the shackle at two points, increasing pry resistance compared to single-locking designs. The hardened steel and alloy shackle resists cutting. A proprietary rustproofing treatment extends service life in outdoor and damp conditions. Locksmiths, facilities maintenance techs, and general contractors routinely specify this lock for gate, equipment, and utility enclosure security.

The 3KALF3186 is suited for residential and light commercial security tasks including securing gate hasps, tool storage, electrical panel enclosures, and utility access points. The 1-9/16 inch body size fits standard hasp openings commonly found on sheds, storage units, and equipment cabinets. It is sold individually and is appropriate wherever a durable, weather-resistant padlock is required.

Installation Notes

Installation requires no special tools — insert the shackle through the hasp or staple and press closed until both locking points engage.
