About the Master Lock 1LN Laminated Steel Padlock
Most padlocks top out at a couple of inches of shackle clearance. The Master Lock 1LN extends to 5-3/4 inches. Therefore, it’s the go-to choice when you need a laminated steel padlock that reaches where others can't. It does so without sacrificing commercial-grade drilling, prying, and picking protection.
Master Lock 1LN
The Master Lock No. 1LN Laminated Steel Padlock features a 1-3/4in (44mm) reinforced laminated steel body and a 5-3/4in (150mm) tall, 5/16in (8mm) diameter hardened steel shackle for excellent cut resistance. Dual ball bearing locking delivers maximum pry resistance, which makes this lock well-suited for industrial and commercial outdoor use.

Best Used For: Outdoors
Some applications go without a lock because standard shackles cannot reach cable loops, recessed hasps, or irregular gate hardware. The 1LN LAMINATED STEEL PADLOCK fills that gap with extended clearance and dependable construction suited for demanding conditions.
