When it comes to choosing the right door hinges, you can't go wrong with 4 inch door hinges. These versatile and durable hinges are essential for ensuring smooth and secure door operation. Whether you are installing a new door or replacing old hinges, understanding the different types and features of 4 inch door hinges is crucial.

There are various types of 4 inch door hinges available in the market, each with its own unique features and benefits. Let's take a closer look at some popular types:
Butt hinges are the most common type of door hinge and are suitable for both interior and exterior doors. They consist of two leaves joined by a pin, allowing the door to swing open and closed. Butt hinges are known for their strength and durability, making them ideal for heavy doors.
Continuous hinges, also known as piano hinges, are long and continuous strips of metal that run the entire length of the door. These hinges provide smooth operation and distribute the weight of the door evenly, reducing stress on the frame. Continuous hinges are commonly used in commercial settings.
Ball bearing hinges are designed with ball bearings between the knuckles to provide smooth and quiet door movement. These hinges are ideal for high-traffic areas where noise reduction is important. They are commonly used in residential and commercial applications.
When selecting 4 inch door hinges, there are several factors to consider:
The material of the hinges determines their strength, durability, and resistance to corrosion. Common materials include steel, brass, and stainless steel. Consider the door's location and exposure to elements when choosing the right material.
Ensure the hinges can support the weight of your door. Manufacturers specify the maximum weight capacity for each hinge. Choose hinges that exceed the expected weight of your door to ensure smooth operation.
The finish of the hinges affects their appearance and resistance to tarnish or rust. Popular finishes include brass, nickel, chrome, and oil-rubbed bronze. Choose a finish that complements your door and overall decor.
Consider the installation process and whether you need full mortise, half mortise, or surface-mounted hinges. Full mortise hinges require a recessed area to be cut into the door and frame, while surface-mounted hinges are mounted on the surface of the door.
