Keeper Shim
Keeper Shims are small but critical components of window and sliding door parts that often go unnoticed until they malfunction. A keeper shim is a small, thin piece of metal or plastic that acts as a spacer between the keeper and the sash. It helps to prevent the sash from binding against the keeper mechanism and allows the sash to glide smoothly along the track. If the keeper shim is missing or improperly installed, it can result in friction, sticking, and other problems that can make it difficult to open or close the window or sliding door.
In this article, we will provide a comprehensive guide to Keeper Shims and their role in window and sliding door parts. We will explain what a keeper shim is, why it is important, and how it functions in the overall mechanism of a window or sliding door. We will also discuss the various types of keeper shims, how to identify them, and how to replace them if they become damaged or worn. By the end of this article, you will have a better understanding of what a keeper shim is and how it can affect the performance of your windows and sliding doors.
What is a Keeper Shim?
A Keeper Shim is a small, thin piece of metal or plastic that is installed between the keeper and the sash of a window or sliding door. It acts as a spacer and helps to prevent the sash from binding against the keeper mechanism. The keeper is the part of the window or sliding door that engages with the locking mechanism to keep the window or door in place. The keeper shim is installed behind the keeper and serves as a cushion or spacer to ensure that there is enough clearance between the keeper and the sash.
Why is Keeper Shim Important?
Keeper Shims are critical components of window and sliding door parts because they help to maintain the proper alignment and operation of the window or door. Without the keeper shim, the sash could bind against the keeper mechanism and prevent the window or door from opening or closing properly. Over time, wear and tear on the keeper shim can cause it to deteriorate or become damaged, which can result in a variety of problems, including sticking, misalignment, and reduced energy efficiency.
How Does Keeper Shim Work in the Overall Mechanism of a Window or Sliding Door?
The keeper shim works in conjunction with the keeper mechanism to ensure that the sash of the window or sliding door moves smoothly and stays properly aligned. The keeper mechanism consists of the keeper, the lock, and the latch, which all work together to keep the window or door in place. The keeper shim is installed between the keeper and the sash to provide a cushion and prevent friction, which can cause the sash to stick or become misaligned.
Types of Keeper Shim
There are two primary types of keeper shims: rigid keeper shims and flexible keeper shims. Rigid keeper shims are generally made of metal or hard plastic and are designed to provide a more stable and rigid surface for the sash to glide against. Flexible keeper shims, on the other hand, are typically made of softer plastic or rubber and are designed to provide a more cushioned and flexible surface for the sash to glide against. Both types of keeper shims can be effective, depending on the specific needs of the window or sliding door.
Identifying Keeper Shims
Identifying keeper shims can be challenging, as they are often small and may be difficult to access. However, there are a few simple steps that you can take to identify the type of keeper shim that you have. First, remove the sash from the window or sliding door and inspect the keeper mechanism. Look for a small metal or plastic component that is installed between the keeper and the sash. Once you have located the keeper shim, take note of its shape, size, and material. This information can be helpful when choosing a replacement keeper shim.
Replacing Keeper Shims
If your keeper shim has become damaged or worn, it is important to replace it as soon as possible to prevent further damage to your window or sliding door. To replace a keeper shim, first, remove the sash from the window or sliding door. Next, locate the keeper mechanism and remove the old keeper shim. Clean the area around the keeper mechanism to remove any debris or old adhesive. Finally, install the new keeper shim and reattach the sash to the window or sliding door.
