    These did the job but for my use case where I occasionally remove the pipe from the connector which is mounted to the wall, the end of the pieces seem to push together and it’s hard to get the pipe back in without taking pliers and bending the two pieces apart. I’ve taken it off and re-mounted the pieces further apart and have the same result. It’s an annoyance but it’s working for my purpose.

    Terrible experience. Company shipped order to wrong address. Items would have arrived late anyway. Not worth the cost. Easy connectors for conduit can be made with a cheap angle grinder and drill. The cheapest welder makes far superior connectors. Making your own connectors adds maybe 3 hours to a build. This greedy company wants to do direct sales only which makes you wait days (if they show up at all). Definitely not worth the high price or the cost of adding uncertainty to your project. Stay away.
