Surface Door Closers: The Complete Guide

Surface door closers are essential devices used in many buildings to control the opening and closing of doors automatically. They offer convenience, safety, and efficiency, making them a popular choice across various industries. Whether you’re a homeowner or a facilities manager, understanding the functionality and benefits of surface door closers can help you make informed decisions when choosing door hardware. Surface door closers from National Lock Supply are essential for smooth, controlled door operations in both residential and commercial settings. Our closers are designed to ensure doors close securely, enhancing safety and reducing energy costs.

What Are Surface Door Closers?

Surface door closers are mechanical devices installed on the surface of doors to ensure they close automatically after opening. They consist of a hydraulic mechanism housed in a metal casing attached to the door frame and the door itself. When a door is opened, the closer uses hydraulic pressure to control the speed of the door’s closing motion. This mechanism ensures the door closes smoothly and securely without slamming.

Types of Surface Door Closers

1. Regular Arm Closers: These are the most common type, where the closer is mounted to the door frame and the door itself via a connecting arm.

2. Parallel Arm Closers: In this type, the arm runs parallel to the door instead of being mounted on the surface of the door, which can be useful in specific architectural situations.

3. Top Jamb Closers: These closers are mounted on the frame above the door and are used where there isn’t enough space on the door itself.

4. Slide-track Closers: They have a slide track that mounts on the push side of the door, providing better control over the door’s closing action.

Benefits of Surface Door Closers

1. Safety: Surface door closers prevent doors from slamming shut, reducing the risk of accidents, especially in high-traffic areas.

2. Accessibility: They make it easier for everyone, including those with mobility issues, to navigate through doorways safely.

3. Energy Efficiency: By ensuring doors close properly, surface door closers help maintain consistent indoor temperatures, reducing heating and cooling costs.

4. Security: They ensure doors are always closed and latched, enhancing security in buildings.

5. Durability: Made from sturdy materials, surface door closers are designed to withstand frequent use and adverse weather conditions.

Choosing the Right Surface Door Closer

When selecting a surface door closer, consider factors such as:

  • Door Size and Weight: Ensure the closer is suitable for the size and weight of your door. 
  • Traffic Volume: Choose a closer that can handle the expected volume of traffic. 
  • Aesthetics: Some closers are designed to be less conspicuous, maintaining the building’s architectural integrity. 
  • Installation Requirements: Consider whether the closer can be easily installed on your existing doors.

Installation and Maintenance Tips

  • Professional Installation: It’s recommended to have surface door closers installed by a professional to ensure they function properly.
  • Regular Maintenance: Schedule regular inspections and maintenance to keep the closers in optimal condition.
  • Adjustment: Most closers allow for adjustment of closing speed and force, which should be periodically checked and adjusted as needed.
