Boli Grill Roller Shutter Door Central Lock - Middle Lock with Key - Guangdong Boli Industry

Usage & Installation

Proper installation is key to the lock's performance. While specific instructions may vary depending on the door model, the general process involves:

1. Marking the Position: Determine the precise location on the door where the lock will be installed, typically at a convenient height in the center of the door panel.
2. Drilling Holes: Use a power drill to create the necessary holes for the lock cylinder and mounting screws. The size of the holes must match the lock's specifications.
3. Fixing the Lock: Insert the lock cylinder from the outside and secure it from the inside using the provided screws and plates. Ensure it is firmly fixed and aligned correctly.
4. Installing the Strike Plate: On the door frame or the corresponding locking point, install the strike plate (the part the lock bolt engages with) to ensure a secure fit when locked.

Required Tools: Electric drill, screwdrivers, wrench, measuring tape, and marker.

It is recommended to consult a professional installer or refer to the door manufacturer's guidelines for detailed installation steps to avoid damaging the door or lock.

Buying Guide

When purchasing a central lock for your roller shutter door, consider the following factors:

• Compatibility: Ensure the lock is compatible with your specific door model, including door thickness and material.
• Lock Type: Central locks are common, but bottom locks are also available for additional security. Choose based on your security needs and door design.
• Key Type: Common key types include cross (cruciform), flat, and dimple keys. Cross keys are often used in roller shutter door locks for their balance of security and convenience.
• Material: Look for locks made from durable materials like hardened steel or copper alloy to resist forced entry and corrosion.
• After-sales Service: Choose a supplier that offers clear warranty terms and reliable after-sales support, such as technical assistance and spare parts availability.
