Window Sash Pivot
A window sash pivot is a crucial component of any double-hung window. It plays a crucial role in allowing the upper and lower sashes of a window to move smoothly and securely within the window frame. Without a properly functioning sash pivot, a window can become difficult to open or close, or even become completely stuck. In this article, we will explore what a window sash pivot is, how it works, what types of sash pivots are available, and what to look for when choosing a replacement part. We will also discuss the importance of getting the right replacement part and how to identify the correct part for your window.
What is a Window Sash Pivot?
A window sash pivot is a small metal component that connects the sash of a double-hung window to the frame. It allows the sash to pivot on an axis, which enables the window to be opened and closed. Sash pivots are typically located on the sides of the window frame near the upper sash, although they can also be located at the bottom of the frame or in the middle, depending on the window design.
Sash pivots consist of two parts: the pivot pin and the pivot shoe. The pivot pin is a small metal rod that is inserted into a hole in the sash. The pin then fits into a slot in the pivot shoe, which is attached to the frame. When the sash is raised or lowered, it pivots on the pivot shoe, allowing it to slide smoothly within the frame.
How Does a Window Sash Pivot Work?
When a window sash is raised, the pivot shoe rotates on its axis, allowing the sash to move up and down within the frame. The pivot pin slides along the slot in the pivot shoe, keeping the sash in place as it moves. When the sash is lowered, the pivot shoe rotates in the opposite direction, again allowing the sash to move up and down while remaining securely in place.
What Types of Window Sash Pivots Are Available?
There are several different types of window sash pivots available, each designed to fit specific types of windows. Some of the most common types of sash pivots include:
– Spiral balance sash pivot: This type of pivot uses a spiral balance to counterbalance the weight of the sash, making it easier to open and close. It is typically used in windows that are larger or heavier than average.
– Block and tackle sash pivot: This type of pivot uses a system of cords and pulleys to raise and lower the sash. It is commonly used in older windows that do not have spiral balances.
– Cam pivot sash pivot: This type of pivot uses a cam mechanism to secure the sash in place. It is often used in modern windows and is known for its ease of use and durability.
– Side-load sash pivot: This type of pivot is designed for windows that have a narrow frame. It allows the sash to be removed from the side of the frame for easy cleaning and maintenance.
What to Look for When Choosing a Replacement Sash Pivot
If you need to replace a window sash pivot, there are several things you should consider before making a purchase. These include:
– Window size and weight: Make sure you choose a sash pivot that is designed to support the size and weight of your window. If you choose a pivot that is too weak, your window may not operate properly. If you choose a pivot that is too strong, it may not fit properly in your window frame.
– Type of pivot: Choose a pivot that is designed for the type of window you have. For example, if you have an older window that uses a block and tackle system, you will need a pivot that is designed to work with this type of mechanism.
– Material: Look for a pivot that is made from durable materials that can withstand the wear and tear of regular use. Stainless steel is a popular choice, as it is strong and corrosion-resistant.
– Brand: Choose a reputable brand that is known for producing high-quality window hardware. This will ensure that you get a reliable part that will last for years.
How to Identify the Correct Sash Pivot for Your Window
Identifying the correct sash pivot for your window can be challenging, especially if you do not have a lot of experience with window hardware. However, there are a few things you can do to make the process easier.
First, look for any identifying marks on the pivot itself. Many manufacturers will stamp the pivot with their logo or product number, which can make it easier to find a replacement.
If you cannot find any identifying marks, you may need to take precise measurements of the pivot and the window frame. This will help you determine the size and type of pivot you need. You can also take the pivot with you to a hardware store or window supply company to get help identifying the correct replacement.
