It is best if
you measure your existing cover and not your spa. In order to
get the proper length and width, measure across the seam,
then perpendicular to that.
If you do not have a cover to
measure from, then you must measure
all the outside dimensions of the spa. The cover has a 2" flap around
the edges of the spa called a skirt. The skirt must easily sit over the
edges of the spa, with a little room to spare.
It is always better to make
the cover size a little bit bigger than your
spa when measuring. If you make a mistake, and measure too small,
the cover will not fit properly, will not sit flat and will not hold the heat in.
All Red's Covers come with
Tie Downs and locks that can either be
attached to the wood spa cabinet or be screwed to a deck.
Spas come in a variety of "standard" shapes. Determining your units
shape will help you order the proper cover.

ASTM CERTIFIED
Method # 1 for determining radius: 
Method # 2 for determing radius: Another
way to measure the radius is by placing a carpenter's square on the outside of your spa.
The distance between the corner of the carpenter's square and the {a}place where it
touches the spa (A) equals the radius of the curve (B).
