American Lock A11KA-43738 Aluminum Padlock 1-3/4 in

Product Description

The AMERICAN LOCK A11KA-43738 is a keyed-alike aluminum padlock designed for industrial and commercial locking applications where a lightweight, corrosion-resistant body is required. The rectangular gray aluminum body measures 1-3/4 inches wide and 3/4 inches thick. The shackle is constructed from boron alloy, offering cut resistance, with a 5/16-inch diameter, 3/4-inch clearance width, and 2-inch height. A 5-pin cylinder provides solid key control. Electricians, maintenance technicians, and facilities personnel commonly use this padlock for lockout/tagout (LOTO) programs and general access control.

This padlock suits residential, commercial, and light industrial environments. Its keyed-alike configuration means multiple A11KA-43738 units can be operated by the same key, streamlining access management across multiple lock points on equipment, panels, gates, and storage units. The aluminum body keeps overall weight low at 0.5 pounds, making it practical for portable LOTO kits or applications where minimizing load on a hasp or chain is a priority.

Installation Notes

Installation requires no tools. Verify that the hasp or lockout device staple clearance accommodates a 5/16-inch shackle diameter and 3/4-inch shackle width before use. When used in LOTO applications, follow OSHA 29 CFR 1910.147 lockout/tagout procedures and confirm the shackle is fully engaged and locked before releasing stored energy. Do not force the shackle or use the padlock as an anchor point for lifting.
