Product Details

The Master Lock No. 5KALJ laminated steel padlocks, keyed alike - multiple locks open with the same key - feature a 2 in reinforced laminated steel lock body providing extra strength and a 2-1/2 in tall, 3/8 in diameter hardened steel shackle for excellent cut-resistance. Dual ball bearings locking for maximum pry-resistance making it ideal for industrial applications and the non-rekeyable, 4-pin W1 cylinder helps prevent picking. Keyed alike padlocks available to order to match other locks with the W1 cylinder.

  • Pair of brass keys included with every lock
  • 2-1/2 in tall, 3/8 in diameter hardened boron alloy shackle for superior cut-resistance
  • Dual ball bearing locking for maximum pry-resistance
  • Non-rekeyable, 4-pin W1 cylinder helps prevent picking
