Stainless steel carbon steel sliding door lock, a 90-degree barn door hasp lock with black carbon steel shackle, for warehouse and security use
90-Degree Hasp Lock for Securing Sliding Doors, Barns, and Warehouses

This sliding door lock features a 90-degree hasp design, engineered to provide a secure physical barrier for doors that slide or swing. It is a practical choice for agricultural buildings, storage units, workshops, and any outbuilding where a simple, effective locking mechanism is required. The product is offered in material variations, allowing you to select the most suitable option based on exposure to weather and the desired level of corrosion resistance.
Features and Construction

The lock's primary feature is its 90-degree hasp, which is designed to mount securely on a door and its adjacent frame. This shape provides a solid anchor point, making it suitable for robust applications where security is a priority. The product listing confirms it is suitable for barn doors and sliding doors.
Material and Build
You can select from two primary material constructions. The first is a black carbon steel buckle lock, which offers a classic, sturdy option. The second is a stainless steel version, which provides inherent resistance to rust and corrosion, making it a sound choice for damp or outdoor-adjacent applications. The shackle, the U-shaped part of the lock, is also available in matching flat black carbon steel or flat stainless steel.
Size and Practical Fit
The product is supplied as a single unit, comprising the lock body and its corresponding hasp. The 90-degree design of the hasp is a key differentiator, as it is specifically shaped to fit around the corner where a door meets its frame. This design ensures the locking point is secure and aligned correctly when the door is closed, which is essential for an effective physical barrier.
Uses and Placement

This lock is designed for straightforward physical security applications. Its stated scope of application includes barn doors and sliding doors, indicating it is built to handle the specific mechanics and security needs of these door types. It is a functional solution rather than a decorative one.
Event or Professional Use
In professional or commercial settings, such as warehouses, storage lock-ups, or agricultural sheds, this lock provides a basic, reliable method of securing premises. Its robust construction options mean it can be chosen to withstand the environmental conditions typical of such locations, from dusty workshops to outdoor-facing barns.
Everyday Home Use
For homeowners with garden sheds, garages with sliding doors, or external workshops, this lock offers a simple upgrade or replacement for existing, worn-out security fixtures. The choice between carbon steel and stainless steel allows for consideration of local weather conditions and the desired maintenance level.
