This extra spacer ring is for use with the Fastway Flip jack foot that fits a 2" jack, 1-3/4" inner-jack tube.
NOTE: Each Flip jack foot comes with one ring supplied in the package. Order additional rings only if necessary after installation of your jack foot to take up additional space left by some jacks that do not retract far enough for the Flip foot to raise completely. This is a rare occurrence, and can usually be avoided by following proper installation procedures outlined in the Flip installation instructions.
