How To Measure The Spa Cover’s Radius Corners

To correctly measure the radius, view the instructional images and steps below.

  • Place a straight edge squarely against the side of the tub on one side of the radius to be measured.
  • Place a ruler square against the opposite side.
  • Have the straight edge hit the ruler at the “0” and your radius will be where the ruler hits the straight part of the tub as indicated in the below photos.
