Oval and cylindrical glass beads provide modelers with an approximation of the many shapes used on pole lines over the years.  Stack several on a pin for high voltage standoffs or use singly on telegraph arms or traction overhead.  Bead size varies slightly in any lot.  Sizes are an average of measured samples.

Each package contains 500 black beads measuring .048" diameter by .030" high with a capacity of one 26 gauge wire or two 32 gauge wires.
