Complete Guide to Gas Strut Sizes and Dimensions

Selecting the right gas struts size is the key to smooth lifting, controlled motion, and long-term durability. Whether you’re designing cabinets, truck tool boxes, camper shells, or industrial equipment, choosing the correct size ensures safety, stability, and performance.

In this guide, we’ll break down everything you need to know about gas strut sizes, dimensions, and how to read a size chart correctly.

The specifications of gas struts are typically determined by four core dimensions: rod and tube diameter, extended length, stroke and force (Newtons).Standard sizes are often categorized by the rod-to-tube ratio, such as 6-15, 8-18, 10-23, and 14-28.

Not all gas struts are created equal. Even small differences in length or force can dramatically affect how your application performs.Choosing the wrong size can result in:

That’s why understanding gas strut sizes is more than just measuring length — it’s about matching stroke, force, and mounting geometry.

When evaluating gas strut dimensions, there are three primary measurements to consider:

The GASTAC gas strut size chart offers a clear and organized overview of rod and tube diameters, extended length, stroke, and force ranges. Designed for engineers, distributors, and OEM buyers, it simplifies model selection, speeds up replacement matching, and reduces sizing errors, ensuring precise fit and reliable performance in every application.

Common applications that depend on accurate gas strut sizes include cabinet doors, truck tool boxes, camper shell windows, RV compartments, medical beds, adjustable desks, and industrial machine covers. Correct rod diameter, extended length, and stroke ensure smooth lifting, controlled motion, and safe support. Proper sizing prevents misalignment, excessive force, and premature wear, guaranteeing long-term stability and user safety.

When choosing gas strut sizes, consider the load weight, mounting angle, required stroke, extended length, and rod and tube diameters. Proper force rating ensures smooth operation, safety, and longevity. Accounting for application type and space constraints helps achieve precise fit and reliable performance.

The weight of the object the gas strut will support is the primary consideration. Gas struts come in various force ratings, measured in Newtons (N). Knowing the object’s weight helps determine the appropriate force needed to lift and hold it securely (Gas Struts Cover Weight Calculator).

Gas struts are offered in different lengths and stroke sizes. To select the right size (Gas Strut Length Calculator):

Proper placement of the gas strut’s mounting brackets is essential. Typically (Gas Strut Length Formula):

Consider how easily the application should open or close. A gas strut with excessive force can make opening difficult, while one with insufficient force may fail to hold the application open (Gas struts Force Calculator).
