How to install gas struts: 3 easy steps to follow

3 easy steps to finsh gas struts installation, make cabinet door support easier

Installing gas struts may seem daunting on your first try, actually, it’s straightforward as long as you grasp the method and gather the required tools beforehand. Apexstone provides mounting instructions including diagrams tailored to various specifications and sizes, so it’s crucial to select the right installation point based on what you’ve purchased. In the upcoming sections, we’ll walk you through three easy installation steps.

Step 1: Calculating and Buying Gas Struts

Choosing the right gas struts depends on your specific requirements, with varying installation methods for different scenarios. Our online gas struts calculator simplifies this process for you, free of charge. Just input four measurements into the form, and the system will instantly provide the detailed specifications you will need. Based on these results and your actual needs, then you can select the appropriate lift supports for purchase.

Step 2: Installing the Gas Struts

Once you’ve determined the gas struts required, the crucial step in installation is selecting the right mounting point. Refer to the installation diagram corresponding to the size you’ve purchased. For instance, if you bought a pair of 10-inch 100N gas shocks, consult the instruction manual for the specific size details, as depicted in the image below.

In the image, there are two clearly marked installation points labeled as A and B. These are the points where we need to mount the gas struts. Simply follow the dimensions provided in the picture to drill the necessary holes for installation. For a 100N 10-inch gas shock, the top mounting point should be 2.8 inches from the box hinge, while the bottom mounting point should be 8.9 inches from the horizontal line of the piano hinge. However, it’s important to note that these installation points are not rigid, some adjustments may be needed based on your specific situation. If the pressure exerted by the gas shocks significantly exceeds the weight of the cover, a more horizontal installation may be preferable. Conversely, if the pressure is much lower than the weight of the cover, a slightly more vertical installation might be suitable. Regardless of your choice, ensure that the metal rod should be installed in a downward direction.

Step 3: Evaluate Performance and Adjust Installation Points if Necessary

The primary goal of installing a gas spring strut is to enhance convenience. Hence, it’s crucial to conduct a thorough performance check and make any required adjustments. We need to ensure that the desired outcome is achieved. If not, it’s essential to address the issue promptly. Here’s a further explanation:

The desired outcome is straightforward: once the gas struts are installed, gently push the cover, allowing it to close naturally if you install them in the storage chest. Following the installation method I outlined earlier, with the metal rod pointing downward, will help reduce the slamming noise as it will result in a slightly slower at the final travel. However, it’s important to note that lift support isn’t a damper, so don’t expect an ideal slow closing function. For applications requiring a soft closing function, Apexstone damper gas springs are recommended.

Once the lid is fully closed, gently lift the door panel to around a 40-degree angle with your hands and then release. If the outcome is satisfactory, the lid should smoothly lift to 90 degrees and stay well-supported. This indicates success—congratulations!

If you encounter the following situations during the installation process, adjustments to the installation points may be necessary:

(1) The lid cannot close, or the gas struts are difficult to compress.
(2) The lid cannot lift automatically.

These scenarios indicate specific problems. The first suggests that the lift support pressure is excessive, while the second suggests insufficient pressure in the gas struts. To address these issues, we offer the following adjustment options:

For the first case, where the gas strut’s strength exceeds the required force, resulting in difficulty closing the lid, a more horizontal installation is needed. You can achieve this by slightly lowering the top mounting point, which in turn shifts the bottom mounting point further away.

In the second case, where the lift support’s force is insufficient to support the lid, a more vertical installation can resolve the problem.

You can follow the provided diagram to perform these adjustments effectively.

Installing gas struts is straightforward. By following the three outlined steps, even if it’s your first time, you can probably finish within 20 minutes. Let’s plan a time, maybe in the afternoon when you’re available, to get this done hassle-free.

While the process is easy, you might encounter some challenges. But don’t worry, if you have any questions—whether during purchase or installation—feel free to reach out to us. Our engineers are ready to help you choose the right product and ensure a smooth installation.
