What can be said about there simple but build is excellent cables thread on smoothly and long enough. I used two sets to build a wall pass through on a grounded copper plate worked out perfectly.

Works well, was easy to install. Just be aware that they have no mounting screws so you have to purchase those separate...which in the long run is better depending on what you are mounting for.

Nice deep centers take a full sized PL-259 with no issue. Well machined and all around, good product. Id buy again

They seem to be the quality I expected in the price range. There are better made connectors to be sure, but for the purpose that I bought them for (an offroad trailer) they fit the bill. No noticeable signal loss.

Working so far, I have mounted these to a copper plate so I can run 6 coax cables out a wall and ground all of the cables at one time.

This is used on a manpack setup for a 2m radio. 3/4in hole for the pass through. 1in screws work with 3/16 aluminum. Nice connectors

Have not used yet but they look of good quality bought to make a window pass-through havent had time to do it yet

these work better than those barrel connectors and nuts. nice clean install if you use the correct hardware.

Excellent product as advertised.

Used to transition through the firewall...works just fine
