Its been a struggle getting the coupler at the exact size. Last place I ordered did not reflect the correct sizing but here at B&H I never have an issue! Appreciate the teams there that work hard and provide for us all!

I have a handful of couplers from before the days of SDI video. Could I expect those to work with SDI cables or would I need to purchase this product? Thanks.
