About the 311LH Covered Laminated Padlock

Outdoor conditions don't forgive a weak lock. The Master Lock 311LH is a covered laminated padlock with tough thermoplastic layers over a laminated steel body. It offers weather protection and serious cut resistance in one compact package. It's a go-to pick for anyone securing gates, storage units, or anything exposed to the elements.

Master Lock 311LH

The Master Lock No. 311LH Covered Laminated Padlock comes in a Keyed Alike (KA) configuration, meaning multiple locks open with the same key for simplified access management across several entry points.

The 1-9/16in (40mm) wide laminated steel body pairs with a 2in (51mm) tall, 9/32in (7mm) diameter hardened steel shackle for superior cut resistance. A black weather-resistant thermoplastic shell keeps out moisture, dirt, and grime, making it a dependable choice for outdoor and heavy-use environments.

If you're looking to explore more options, our collection covers a wide range of padlocks for every security level.

FAQs

Is the Master Lock 311LH suitable for outdoor use in harsh weather?

Yes. The black thermoplastic cover on the 311LH is designed to block out moisture, dirt, and grime. Suitable for exposed outdoor environments such as gates, fences, and storage facilities.

What is the difference between Keyed Alike and Keyed Different options?

Keyed Alike means multiple locks operate with a single shared key, simplifying access across several entry points. Keyed Different means each lock has its own unique key, giving you individual control over separate access points.

How does dual ball bearing locking improve security?

Dual ball bearings engage on both sides of the shackle when locked, making it significantly harder to pry or force the shackle open. This mechanism adds a meaningful layer of physical resistance beyond what a standard single-locking padlock offers.
