Prime-Line KC10HD Safety Spring Door Closer - Self-Closing Hinged Doors, Diecast, White

The Prime-Line KC10HD Safety Spring Door Closer allows you to easily convert your hinged door into a self-closing one. Installation is straightforward, as the closer and plastic slide plate are surface-mounted. This spring door closer can handle doors weighing up to 150 pounds and can be used on both left and right-handed doors.

These safety spring-activated door closers are constructed of diecast materials and come in a white painted finish. They are U.L. listed with a 1/2 hour fire rating, making them a reliable choice for safety. The closers feature an adjustable closing force and speed, providing customizable performance.

The closer arm has the ability to swing a full 180 degrees, but once installed, the door's distance of swing will be reduced to the point of contact with the bullet-shaped housing of the closer. This pushing-closed operation, rather than a pulling-closed method, eliminates the need for a hold-open feature.

For outdoor or exterior use, consider the KC50HD (white) or KC57US (brown) models, which are designed for lightweight gates and screen doors. These options offer rust and weather resistance for a more durable closure solution.

In addition to the standard white finish, these door closers are available in various other colors and finishes, including black, brown, chrome plated, and satin chrome plated, allowing you to coordinate with your door's aesthetic.

All necessary fasteners and installation instructions are included with the Prime-Line KC10HD safety spring door closer. For a seamless DIY project, be sure to view the manufacturer's How-To Installation Video, which can be accessed through the provided link.

When installing the closer, ensure that the closer and tension arm rest on the same plane, not at an angle due to any molding offset. This will ensure proper operation and prevent potential issues.

Adjusting the tension on these safety spring door closers is a straightforward process. However, it is important not to exceed 4 quarter turns of the tension arm, as this can lead to spring failure.

To maintain the door closer's performance, it is recommended to apply wheel bearing grease to the spring coils when the spring is not under load. Avoid using lubricants like WD-40, as they can break down the lubricating grease.

It is important to note that this door closer is rated for up to 150 pounds of closing force, which includes the weight of the door and any wind force trying to keep the door open. In windy areas or with particularly heavy doors, you may need to install two closers to ensure reliable closure.

In summary, the Prime-Line KC10HD Safety Spring Door Closer provides an easy way to convert your hinged door into a self-closing one. With its adjustable features, versatile installation, and durable construction, this door closer can be a great addition to your home or commercial space.
