The Spring Holder kit attaches to the underside of the carriage to hold the springs close to it. There are 2 different spring holders for the various reformers:
- A plastic Spring Holder for use on Merrithew™ At-Home and SPX club or group Reformers works with the existing molded Spring Holders;
- A metal Spring Holder is for use on Merrithew™ Professional Series Reformers (SPX Max, V2 Max, and Rehab V2 Max).
The universal assembly tool is used to attach it to the reformer.
