Main Lock Body

Material: Galvanized steel sheet, rust-proof and with a certain degree of resistance to violent impacts, suitable for the installation environment of roller shutter doors.

Structure: Center-opening keyhole design; turning the key drives the internal mechanism, which in turn extends and retracts the upper and lower locking rods to achieve locking/unlocking. The latching structures at both ends connect the locking rods and are the core control unit of the entire lock system.

Compatibility: Universal design, compatible with most center-opening roller shutter doors. Installed in the middle of the door, the locking rod can extend to the upper and lower door frames for multi-point locking.

Locking Rod and Guide Accessories

Long Strip Locking Rod: Connects the upper and lower ends of the main lock body. When the key is turned, the locking rod extends/retracts, inserting into the keyhole in the door frame to form two-point locking, significantly improving anti-theft performance.

Locking Rod Guide Seat: Installed on the door frame or roller shutter track, it provides support and guidance for the locking rod, preventing it from shaking or deforming, ensuring smooth locking.

Two keys are included as standard, compatible with the lock cylinder, to meet the needs of backup and multiple users. Some models support multi-key opening or custom management keys.

• Applicable Scenarios: Suitable for shops, garages, warehouses, roller shutters, and other locations requiring high security. It is a standard security accessory for traditional roller shutters.

  Core Advantages:
  Multi-point Locking, Strong Anti-theft: The main lock body drives the upper and lower locking rods, achieving two-point locking from the top and bottom. Compared to single-point locks, it is much harder to force open, significantly improving anti-theft performance.
  Universal Compatibility, Easy Installation: The universal structure is compatible with most standard roller shutters. Complete accessories are included, allowing direct replacement of old locks with low installation difficulty.
  Durable and Robust: Made of galvanized steel, it is corrosion-resistant and impact-resistant, suitable for high-frequency use and complex environments such as shops and warehouses, with a long service life.
  Simple Operation: Key-controlled switch, no external power supply or complex operation required. It can operate normally even in power outages or environments without electricity, ensuring high reliability.
