PACLOCK’s LFIC-Y6-3B padlock features a 3/8” thick hardened steel shackle; is precision CNC machined in the USA for quality and dependability; and works with your 6-pin large format Yale® Y6 and Medeco® M31 compatible cores. The LFIC-Y6-3B is machined from solid brass, designed specifically for the harshest elements, and ideal for heavily corrosive environments.

The LFIC-Y6-3B features a non-key retaining brass actuator and dual locking stainless steel ball bearings — with our design, PACLOCK significantly reduces the ability for the lock to be shimmed and pulled. PACLOCK provides a key retaining option to ensure your padlock gets locked.

The LFIC-Y6-3B comes standard with a 1-3/16” hardened steel shackle. With PACLOCK’s quick change shackles, you can easily adapt your padlock to any application with just a turn of a wrench. Change the shackle height or type to meet your needs. Take advantage of PACLOCK’s multiple shackle options.
