Quick Connect Coupling Ring, 1.5 Inch Series, Double Female

The 77791 Light Source Coupling Ring has 1.5 Inch Series female connections on both ends. This Quick Connect model is very convenient to use. Just snap in the two flanged components and they're held firmly. A thumbscrew locks them in place so there is no fiddling with set screws and Allen wrenches. This is particularly useful for setups that you frequently find yourself breaking down. And, they're light tight, so if light leakage is a concern, choose a Quick Connect model.
