Frequently Asked Questions
How do I choose the right free length for my application?
Free length is the unloaded length of the spring. Measure the space available for the spring when it is not under tension, and select a free length that fits within that space while allowing for the desired extension. The range includes lengths from 1/2 in to 4 3/4 in, including metric options like 135.8 mm.
What do the pack quantities (2 PK, 3 PK, 5 PK) indicate?
These indicate the number of springs included in each pack. Choose a pack size based on how many springs you need for your project or to maintain inventory. For example, if you need a single spring, a 2 PK provides a spare.
