Sierra Pacific Engineering and Products manufactures high-quality stainless steel hasps and staples for industrial applications such as cases and crates. We also supply electro-polished stainless steel hasps and stainless steel staples, especially useful for marine applications.

Hasps and staples provide a simple and effective solution to securing doors and protecting valuables and other items in a variety of enclosures. Hasps can be mounted in several orientations, maximizing their usability. They can be used to fasten a wide variety of objects, such as doors, cabinets, drawers, lids and tool boxes. These can be secured with a swivel staple or a simple pin to avoid opening, and can be locked with a padlock to prevent theft.

Some hasps, called draw hasps, also provide tamper protection by covering the mounting fasteners when the hasp is engaged. This gives a clean presentation while increasing security.

SPEP manufactures hasps and staples for every use, whether mounted indoors or outside year round. Our hasps and staples come in various materials and finishes, such as stainless steel, steel, zinc plated, mill finish, black powder coated, and electropolished.
