It would not be recommended for a constant spring to be designed for less than 0.1″ for travel. Variable springs can accommodate that travel. The difference in load will be a function of the spring rate.
The “cold” setting of a variable spring support refers to the installed position and the associated load being carried by the support at that time. The “hot” setting refers to the operating position and subsequently the associated load being carried by the support at that time.
Cold Setting Indicated by the White Diamond on a Variable Spring Support
“Spring can” is the general term used to describe either variable or constant spring supports.

A spring hanger is a subset of either variable or constant spring supports that attach directly to structural steel components and are located above the supported member.
Constant Spring Hangers
Variable springs always must have a difference in load between the hot and cold settings. Whereas in constant springs, the load remains consistent. Additionally, in general, constant springs can provide for a higher amount of travel. (Read More in our Technical Bulletin section)
