Makes for a good jumper or extension or for just connecting BNC monitors without the hassle of fitting your own connectors.

They save time, especially if you are not an installer. I am, so I could make my own, but when I was stocking up my struck with my Security Camera King order the other day, I bought a couple of these for the heck of it since they weren't very expensive. Would you believe I used one already?

Good to use for a local BNC monitor.

This makes a nice little patch cord to run a spot monitor from a camera or even a monitor from a DVR. BNC's are attached firm and are of good quality.
