The black, versatile System Connectors Gender Changers from OP/TECH USA are a set of two connectors, one male-to-male and one female-to-female, that work with any standard size Quick Disconnect connectors. They provide a versatile method for interchanging male-to-female or female-to-male connectors.
Reverse the connectors on an optional Utility Strap Sling to switch from wearing it on your left shoulder to your right shoulder - otherwise, if you attempt a reversal without Gender Changers, you end up moving the adjustment hardware to your front and inhibit the free-sliding features of the sling
Used together, these add three inches of extension for extra slack on your OP/TECH straps
Attach both Gender Changers to each side of an optional Uni-Loop Connector to create a hand strap for your camera
