Spiral balance length

Question

I'm not quite sure what size I should be ordering. The Spiral balance is covered in a white vinyl with a grommeted screw hole at the end. It measures 25 inches to end end of the vinyl sleeve. I nose the sleeve ( about 3/4 of an inch is the end of the spiral balance. It's blue tipped. What measurement should I use, 25 inches or 24 inches? Thanks.

Thanks for posting. The outer tube is the only part you want to measure. If yours is 25" long, then that's what you should go with. What is the diameter of the tube? I believe it will be 5/8", in which case I would recommend our S600-25 spiral balance with a blue tip.
