With the diversification of architectural decoration and security needs, the installation methods and applications of Surface Bolts have sparked extensive discussion within the industry. As a traditional and practical hardware component, Surface Bolts are widely used in door structures in residential, office, and public buildings due to their ease of operation and significant reinforcement.

Function of Surface Bolts

A surface bolt is a mechanical fastening device that attaches directly to the surface of a door leaf. It can be manually pushed or pulled to lock the door leaf to the door frame or floor. Its primary function is to enhance door stability, preventing it from swaying or accidentally opening due to wind, external forces, or prolonged use.

Installation Steps and Key Points

• Selecting a Location: Typically installed at the top or bottom of the door leaf, it can also be installed on the fixed leaf of a double door to ensure smooth insertion into the door frame or floor.

• Measuring and Marking: Accurately mark the bolt base and socket to prevent misalignment and jamming.

• Drilling and Securing: Use an electric drill to drill a hole in the door frame or floor to ensure smooth insertion of the bolt. Securely fasten the bolt base to the door surface with screws. Commissioning and Reinforcement: Repeatedly test opening and closing to ensure smooth sliding and pulling. Adjust the size and position of the gusset plate or socket if necessary.

Installation Risks and Precautions

Experts advise the following points when installing surface latches:

Compliance: If used on fire doors or emergency exits, surface latches may hinder escape and must comply with relevant regulations.

Material Selection: Choose stainless steel or high-strength alloys to ensure long-term resistance to rust and deformation.

Safety: Avoid installing the latch too high or too low in spaces frequently used by children or the elderly to avoid compromising the user experience.

Market and Development Trends

As market demands for both functionality and aesthetics in hardware increase, some companies have introduced innovative products such as concealed surface latches and spring-return latches. These products not only ensure stability but also enhance visual appeal and convenience after installation, and are gradually becoming the industry's trend.
