Alise 4-Inch Padlock Door Hasp

Padlocks are used to lock up storage unit doors, lockers, vehicles and many other objects. While they can be used on their own if you need to secure a chain or something similar, you can’t just stick a padlock on a door or other object. You’ll also need to install a hasp, or a fastening latch made up of a hinged metal plate with slots, to attach the padlock to.

Hasps also include a separate part called a staple. This is the steel loop that the padlock shackle (the top, curved part) goes through. The hinged part has mounting holes. That is where you screw it into the object. When the hasp is closed, its mounting screws should be hidden.

Hasps are made from a variety of different materials. Commercial-grade hasps are usually made from steel. Hasps can also be made from stainless steel, aluminum and other materials.

Heavy-duty hasps are made to prevent others from breaking into protected areas and are sturdy enough to resist sawing, cutting, hammering and other forces.

Straight hasps are designed for flat surfaces but right-angle hasps are good for swinging and sliding doors. Hinged hasps secure hard-to-lock locations like around corners and uneven surfaces. Some of these have up to four parts.

• Heat-treated hasps are more resistant to deterioration and breakage.
• Anti-theft screws are an added security measure.
• Your hasp should be thick enough to withstand breakage.
• Hasp fasteners should always be concealed when the hasp is closed.
• Always keep the keys to your padlocks in a secure location.
