DIAMETERS OF ALL SUNDIAL WIRES

Please check that the diameter of each wire you order will fit in the aperture for which it is intended.

The measurements in mm are more accurate than the measurements in inches.

Also, please do not choose solely based on what fits. Please make sure the gauge you choose is appropriate for the electrical draw of your device or fixture.

Please note that the parallel wire has two dimensions, height and width, since its shape is rectangular rather than round.

Twisted wire is measured at its widest point.
