This is 9 pole D-SUB feedthrough connection ,female to female, D-shape connector in nickel housing. I came across this product when I Was looking for robust way to rewire all our video and multimedia system. I was looking for solder-less connection to mount it on the stage to use with laptop presentations. This connector was out of stock for a while but after few months of waiting thomman finally shipped it without additional shipping cost. It fitted easily on to our existing 19" rack panel, just connected the cable under the stage to the back of the connector and it was done. only negative this was thomman didn't have the colour choice of black.
