How to Measure for New Vinyl Straps Before Ordering Your Replacement Vinyl Straps
Correct Strap Measurement is Essential
|When replacing vinyl straps on outdoor furniture, it is critical that you measure
accurately and perform the correct calculations for optimum strap length. Why? Because if the
straps are too long, they will sag. If they're too short, they will be difficult to install, and
may even warp the chair frame!

What Method of Strapping is Used on Your Furniture?
The first step is to know whether your furniture is single wrapped or double
wrapped. How can you tell?
It's easy - if you can see the fasteners holding the straps in place at the back
of the chair frame, it is single wrapped. If the fasteners are covered over by the strap, it is double
How to Measure for Single Wrapped Straps
Step 1: You must use a flexible tape measure for accuracy. Starting at the hole on one side of
the frame, thread the tape measure around the frame in the same path that the strap will take. Extending it to the
other side of the frame, wrap it around the frame in the same way, and obtain the measurement to the hole on this
Step 2: Deduct 10% from the measurement obtained in step 1. Then round to the nearest 1/2 inch.
This is the length you will order, if ordering pre-cut straps, or that you will cut each strap to off the roll.
One word of caution: if the measurement from step 1 is less than 20", be careful about reducing this too
much. The shorter the strap, the less it will stretch (as a percentage), so go for the longer side of the reduction
so it will be a bit longer than 90% of the measured length. The reverse applies for longer straps.
Let's do some examples...
- If your measurement is 24", ten percent is 2.4" so increase this a little and take off 2½", so your
straps need to be 21½" long.
- If your measurement is 20", ten percent of that is 2", so your straps need to be 18" long.
- If your measurement is 18", ten percent is 1.8" so reduce this a little and take off 1½" - they need to be

How to Measure for Double Wrapped Straps
Step 1 is almost the same as for single wrapped straps, except that you
must wrap your tape measure TWICE around the frames at each side of the chair, just as the strap
will be wrapped when finished. Take the total measurement from hole to hole.
Step 2: The ideal length for double wrapped straps is a little "fuzzy".
Deduct about 10-12% from the measurement you obtained in step 1, then round to the nearest
However, we strongly recommend that you cut and install one strap
per the installation instructions before cutting any more. Wait until it cools, and then
test it to make sure it is tight enough. You can then make any necessary
adjustments to your cut length before proceeding.
Note: Double-wrapped straps should
be difficult to install! More stretching means tighter straps after they cool. But be
careful not to have them so short that they tear at the rivet holes when you stretch
For this reason, we recommend that you do NOT order pre-cut straps when double wrapping.

wrapped straps before ordering.
