To be sure that your mount will fit a particular Wheeley Bar product, it may be
necessary to verify the tip-to-tip distance of the mount. Usually, this measurement
is made with the legs of a tripod fully retracted (the shortest length) and spread
out completely. Alternately, you can measure at your preferred viewing height, but
be sure to allow for the height of the Wheeley Bars (listed with each product).
The tip-to-tip distance is the measurement from the outside edge of the end of one
tripod leg or pier foot (where it touches the ground) to the outside edge of another
tripod leg or pier foot as illustrated below.

The left-hand illustration shows the tripod footprint and the correct tip-to-tip
measurement to the outside of the legs. The center illustration shows a tape measure
being used to determine the tip-to-tip distance. The arrow in the right-hand illustration
shows the correct measuring point at the outside of the leg.

Here are some examples of different types of tripod feet. The tick marks show where
to measure on the outside of the leg to find the tip-to-tip distance. You also need
to be sure that your tripod leg or foot is not too large to fit into the receptacles
cut into the Wheeley Bars. Measure the diameter of the leg or foot and be sure it
is smaller than the listed receptacle size.

For leg style A, with a tubular tip, you need to measure the leg diameter.

For leg style B, with a flat circular foot plate, you need to measure the diameter
of the foot plate.

For leg style C, with a rounded tip, you need to measure the leg diameter.

For leg style D, with a pointed tip, you also need to measure the leg diameter.

For leg style E, with a flat circular leveling foot, you need to measure the leveling
foot diameter.
