Sugatsune HP-660 Weld-on Locking Hasp 2 in Stainless

Product Description

The SUGATSUNE HP-660 is a weld-on locking hasp designed for secure fastening applications where a permanent, tamper-resistant mounting is required. Constructed from stainless steel with an electropolished finish, this hasp resists corrosion and surface oxidation, making it well suited for demanding environments. The arm measures 6 inches in length and the hasp body spans 2 inches in width, with an overall length of approximately 6 inches. Installation requires welding, which delivers a stronger mount than screw-on alternatives. Licensed tradespeople and fabricators working on industrial enclosures, access panels, and utility doors will find this hasp appropriate for applications where security and longevity are primary concerns.

The HP-660 is intended for use on metal surfaces where a weld-on attachment is specified. Typical applications include HVAC equipment enclosures, electrical panel doors, storage containers, and industrial cabinetry. Its electropolished stainless steel construction makes it a practical choice for both indoor and outdoor installations where moisture or chemical exposure may be a factor. The locking design allows for padlock compatibility to restrict unauthorized access.

Installation Notes

Installation of the HP-660 requires welding to a compatible metal substrate and should be performed by a qualified welder or fabricator following applicable local codes and safety standards. Power down all associated equipment and ensure the work area is clear of flammable materials before beginning any welding operation. Do not attempt adhesive or mechanical screw mounting, as this part is designed exclusively for weld-on attachment. Confirm the mounting surface material is compatible with stainless steel welding procedures before installation.
