I only wanted one female to female connector. This did the job.

Works as advertised..

Works as advertised.

they are great value and works as designed. one con is there's not a lot of room around the connector which makes its difficult to screw the cable onto the connector.

a bit hard to plug in the coax in the back but other than that, its great.

Hopefully they are better on a full U rack on a half-U couldn't get them to clip in as the back threaded part of the F-type connector didn't have space to lever into place. You can however take the connector out and clip the keystone in a retighten the connector into the keystone, just you may want to remove the rack and not try to do this in the cabinet. Maybe not the most convenient but it works.
