We first made these as a test for something else and they were too big but one of our regular wholesale customers saw them on the shelf and decided they would work perfectly for this. We changed them a tad and here they are. They come with the basic Star 4" overall diameter, a 5.5" x 1/4" disk, a 3" disk (to open you up for different options), and a 3/4" x 3" Grade 8 bolt with a locknut. The Star is bent at a 20 degree angle on one point to give it some "Traction" on the spring. They are sold in pairs so you get 2 of everything. These are meant to tie down a pig tail coil spring, not a flat coil spring.
