To determine if a cover lifter can be installed on your spa, it's essential to accurately measure the radius of the corners of your hot tub. Follow this simple guide to get the correct measurements using a carpenter's square.

Step 1: Gather Your Materials
Materials Needed: A carpenter's square, a measuring tape, and a marker.

Step 2: Identify the Corners
Look at your hot tub to find the corners you will measure. Ensure the corners are clear and accessible for accurate measurement.

Step 3: Measure the Corner Radius

1. Using a Carpenter's Square:

   • Position the Carpenter's Square: Place the carpenter's square against the side of your hot tub at the beginning of the bend. Ensure that the square aligns with the edge where the spa's side meets the corner.
   • Estimate the Radius: The imaginary point where the corner would meet the square represents the square shape of the tub if it were a rectangle.
   • Measure the Distance: Using a measuring tape, measure the distance from the corner of the hot tub to the edge of the carpenter's square.
   • Record the Measurement: Smaller measurements are safer, as this ensures a more snug fit for the cover lifter.

2. Using a Piece of Wood or Cardboard:

   • Alternatively, you can use a piece of wood or cardboard with a tape measure. Hold the piece against the corner and record the distance to measure the radius.

Step 4: Visual Reference
For a quick visual reference to help you determine your hot tub's corner radius, print the Corner Radius Measurement Guide. Hold this chart against the corner edges of your spa and match the curve to easily find your corner radius.

Step 5: Compare with Cover Lifter Specifications
After obtaining all your measurements, you can determine if a cover lifter will fit your hot tub based on the recorded corner radius measurements.

Conclusion
Now that you have successfully measured the radius of your hot tub corners, you can confidently assess whether a cover lifter will fit your spa. If you have any questions or need assistance, don’t hesitate to contact customer support for further guidance.
