Technical Description
Specifications
Length: 2.5 inches
(1) The Ø4mm rods are fundamental building blocks for constructing optical systems. These cage rods are commonly used as guide rods for cage plates, featuring a non-detachable 4-40 stud on one end and a 4-40 threaded hole on the other. This design allows multiple cage rods to be joined together for use in 16mm cage systems, simplifying the construction of experimental setups.
(2) Available in a wide range of length specifications.
