19mm Optical Rail, 3", Inch

Ealing Optical Rails provide a compact and economical foundation for constructing small-scale intricate optical systems. The heart of the Optical Rail system is a 19 mm wide precision machined aluminum dovetail section rail.
19 mm rails can be connected to give longer lengths. For example, to construct an 18 inch long rail connect a 12 inch rail and a 6 inch rail together.
