American Lock A3901SWO Coreless Padlock
The American Lock A3901SWO is a coreless keyed padlock built for lockout/tagout and high-security applications. It accepts Schlage Everest and Primus LFIC cores so facilities can integrate it into an existing master-key system. The brass body and boron shackle resist cutting and corrosion in harsh environments. It is suited for safety officers and maintenance teams who need controlled access points.
Brass body with boron shackle for heavy use
The 2-inch shackle clearance fits standard lockout hasps, chain links and valve handles without adapters. A 3/8-inch diameter shackle made of boron alloy resists bolt-cutter attacks while the solid brass body withstands weather and chemical exposure. No bumpers are fitted so the lock sits flush against flat mounting surfaces. The six-pin cylinder mechanism operates smoothly with a registered control key.
Sustained outdoor and industrial exposure
Weather-resistant construction prevents internal corrosion during long-term outdoor deployment on gates, enclosures or utility cabinets. The unfinished brass surface develops a natural patina that does not affect structural integrity or locking function. High-security rating reflects resistance to picking and forced entry over repeated daily cycles. California Proposition 65 warnings apply to materials used in the lock components.
