Eleven vertical wires were inside the telescope eyepiece.

Fine vertical wires behind the front glass of the display screen separate the different colors of phosphors into strips.

The transmitter power is applied, or the receiver is connected, between the bottom of the vertical wire and a ground connection.

To increase the top-load capacitance, several parallel horizontal wires are often used, connected together at the center where the vertical wire attaches.

The action is located below, operated by vertical wires that are attached to the backs of the keys.

Judicious use of short vertical wires can substantially reduce overall wire length for faster operation.

A table with a vertical wire is mainly used by hobbyists to cut small and complex shapes such as letters.

See the two large vertical wires on that table at the front of their section?

The vertical wires were used for observing transits of stars, each wire furnishing a separate result.

The aperture grill consists of tiny vertical wires.
