Two Bar Hinge
When it comes to window and sliding door repairs, identifying hardware parts can often be a challenge. Hardware parts are typically small, look similar, and can be difficult to distinguish from one another, especially for those who lack experience in the field. However, with the right knowledge and tools, identifying these parts can become more straightforward and less daunting. In this article, we will focus on one of the most common yet tricky hardware parts: the two bar hinge.
What is a two bar hinge?
A two bar hinge is a type of hinge used on windows and sliding doors that have two sashes. It consists of two parts: a track attached to the window frame and a hinge attached to the sash. The hinge fits into the track, allowing the sash to slide and pivot as needed. Two bar hinges are commonly found in double-hung windows as well as some sliding door models.
Identifying a two bar hinge
Identifying a two bar hinge can be tricky because it looks similar to other types of hinges. However, one way to differentiate it from other hinges is by looking at its shape. A two bar hinge typically has two elongated bars that attach to the track, one on each side of the hinge. It also has two holes on the hinge that line up with two pins on the track. These pins allow the sash to pivot and lock into place.
Another way to identify a two bar hinge is to look at the manufacturer’s label or rating plate. This is typically located on the sash or the frame and will have the manufacturer’s name, model number, and other identifying information. With this information, you can contact the manufacturer or a hardware supplier to get the correct replacement parts.
Replacing a two bar hinge:
If a two bar hinge needs to be replaced, it is essential to obtain the correct replacement part. It is not recommended to mix and match parts or use a different type of hinge altogether, as this can compromise the functionality and safety of the window or door.
To replace the hinge, start by removing the sash from the frame. This is typically done by lifting the sash up and tilting it towards you. Then, use a screwdriver to remove the screws that hold the old hinge in place. Once the old hinge is removed, align the new hinge with the track and use screws to secure it in place. Then, attach the sash back to the frame and test the window or door to ensure it functions correctly.
Common problems with two bar hinges:
Two bar hinges can experience a few common problems, with the most common being wear and tear. Over time, the hinge can become loose or damaged, causing the sash to tilt or not open and close correctly. In some cases, the hinge may need to be lubricated or tightened to resolve the problem. If the hinge is severely damaged, it will need to be replaced.
Another issue that can occur with two bar hinges is rust or corrosion. This can weaken the hinge and compromise the window or door’s security. If rust or corrosion is present, the hinge will need to be replaced as soon as possible.
Two bar hinges play a crucial role in the functionality of windows and sliding doors. Identifying and replacing them when necessary is essential to maintaining a safe and secure home. By understanding the purpose of the two bar hinge, how to identify it, and common problems associated, homeowners and technicians alike can be confident in their ability to keep windows and doors functioning smoothly.
