About the Master Lock 1LF Laminated Steel Padlock
A longer shackle reach changes what a padlock can do. The Master Lock 1LF LAMINATED STEEL PADLOCK keeps the trusted performance of the commercial-grade 1 series while adding a 1-1/2in shackle. This added clearance fits a wider range of gates, fences, and heavy-duty outdoor applications.
Master Lock 1LF
The Master Lock No. 1LF Laminated Steel Padlock features a 1-3/4in (44mm) reinforced laminated steel body and a 1-1/2in (38mm) tall, 5/16in (8mm) diameter hardened steel shackle for excellent cut resistance. Dual ball bearing locking delivers maximum pry resistance. Therefore, this is a well-suited pick 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.
