Product Information

Full details

The Master Lock 131T is a reliable security solution ideal for users needing an effective way to secure gym lockers, storage units, or toolboxes both indoors and outdoors. Its primary benefit lies in the scratch-resistant vinyl-covered aluminum body, which protects delicate surfaces while providing essential corrosion resistance; however, potential users should note that the 3/16-inch shackle diameter is best suited for lighter security needs rather than heavy-duty gate or high-value equipment locking.

FAQs

Can I use these locks outdoors?

Yes, the vinyl-covered aluminum body is designed for corrosion resistance, making it suitable for moderate outdoor use.

Are both keys interchangeable between the two locks?

Yes, the units are keyed alike, meaning any key provided in the package will open both locks.

What is the shackle diameter?

The shackle diameter is 3/16 of an inch.

Will the vinyl coating scratch my gym locker?

No, the vinyl coating is specifically designed to prevent the metal body of the lock from scratching or marking surfaces.

How many pins are in the cylinder?

The lock is equipped with a four-pin cylinder for enhanced security against picking.

What should I do if I lose the keys?

As these are standard security locks, it is recommended to keep one key in a safe, secondary location. If all keys are lost, the lock cannot be opened without professional assistance.

Troubleshooting

Key does not turn smoothly in the cylinder

Apply a small amount of dry silicone lubricant to the key and insert it into the cylinder several times to distribute the lubricant.

Shackle feels stuck when trying to open

Ensure the key is fully inserted into the cylinder and turned to the open position; if it persists, check if the shackle has been deformed by excessive force.

Pros and Cons

Pros

  • Scratch-resistant finish protects surfaces
  • Dual locking levers for enhanced prying resistance
  • Keyed alike system saves time and reduces key clutter
  • Compact size fits most standard locker hasps
  • Lightweight yet durable aluminum construction

Cons

  • Not suitable for high-security outdoor requirements
  • Smaller shackle diameter limits use on heavy-duty chains
  • Vinyl coating can be damaged by extreme impacts

Setup, Compatibility & Care

To set up your Master Lock 131T, simply insert the key into the cylinder and turn it to release the shackle. Since both locks in the package are keyed alike, verify that your provided key operates both locks before putting them into service.

Compatibility: This padlock is designed for standard locker hasps and small storage latches. It is generally not compatible with high-security chains or thick industrial gates due to the 3/16-inch shackle clearance.

Care: While the lock is corrosion-resistant, it is recommended to apply a dry silicone lubricant to the cylinder once or twice a year if the lock is used outdoors to ensure smooth key operation. Avoid using heavy oils which can attract dirt and debris into the four-pin mechanism.
