Butterfly Latch for Flight Cases, Transport Cases, Cabinets, and Professional Equipment Cases
1. Strong Protection:
Due to its recessed installation, the latch does not protrude from the surface of the case. This prevents accidental opening or damage to the latch during handling, stacking, or transport, while also protecting the latch itself.
2. Durable and Sturdy:
Typically made of metal (such as zinc alloy, steel, etc.), it has high strength and durability, capable of withstanding rough handling.
3. Good Sealing:
Most recessed butterfly latches apply significant pressure to the case lid when locked, helping compress the waterproof seal around the case edges, providing dust-proof, moisture-proof, and even water-resistant properties.
4. Easy to Operate:
The “butterfly wings” handle provides excellent leverage, making it easy to open and close with minimal effort, even when the case is tightly secured.
5. Neat Appearance:
The recessed installation gives the case a smoother, more professional, and aesthetically pleasing look.
1. Locking:
The two “wings” are brought together. During this process, the latch’s linkage mechanism pulls a metal hook, which hooks onto the locking pin on the case, pulling the lid and body tightly together.
2. Unlocking:
By pulling the two “wings” outward, the hook is released, allowing the case to be opened. Many models also feature a central locking mechanism that can be secured with a padlock or key, preventing unauthorized opening and enhancing security.
1. Flight Cases/Transport Cases:
Used for transporting audio equipment, lighting equipment, musical instruments, precision instruments, photography gear, and more.
2. Military Equipment Cases:
Requires extremely high durability and protection.
3. Industrial Cabinets/Equipment Cases:
Suitable for outdoor or industrial environments where dust and moisture protection is necessary.
4. Medical Equipment Cases:
Used for transporting sensitive medical instruments.
When purchasing or replacing this type of latch, consider the following points:
1. Material:
Prefer metal materials (e.g., zinc alloy) as they are much sturdier than plastic.
2. Size:
Ensure the latch size matches the existing slot on your case.
3. Color:
Common colors include black, silver, etc. Choose based on the color of your case.
4. Locking Option:
Depending on your security needs, choose between a non-locking model, one with a key lock, or one with a padlock hole.
