Piping Technology has come out with a new line of product where a very short travel spring support is required. Low and behold, it is stacked Belleville Washers. See it in their new catalogue.

Dave, I am the CAESAR II user who mentioned the use of stacked Belleville washers when I was a participant in a CII seminar in Houston. This was well before Piping Technology had come out with their new product line mentioned above.

Regards to all.
