Gas Spring Technical Info > Sizes & Length
A valuable service offered is the production of non-stock or custom compression gas springs to meet specific requirements. Although a wide range of lengths and sizes can be supplied, there is a limit to how short a fully extended gas spring, prop or lift can be made in relation to the stroke.
The minimum extended shoulder length is calculated by referring to the following table and then making a simple calculation. Calculation: multiply stroke by two and add the appropriate factor from the table (all dimensions in inches).

This calculation yields the extended shoulder length of the gas spring. To determine the extended length with fittings, add the “A” dimension of the fittings selected. See Gas Spring Fittings.
