I haven't installed these yet to do full testing, but I punched down a few see how well put together they are, and I don't have any complaints. I'm putting this review up mostly so I can add some images. I wanted to see the inside before I bought these, so I thought perhaps you would like to see it as well. Since the first reviewer, they appear to have added some plastic inserts to keep the wire ends from touching the metal sides. they are tool-less, but the cap seems to do an acceptable job of punching them down. comes with a zip tie to secure the cable.
These are toolless which isn’t what I wanted. You have to clip the wires real short or they short on the metal enclosure. I didn’t trust that I got the wires clipped short enough so I put electrical tape over the wire ends before I closed the metal and zip tied. I will not be buying these again. Not sure why they don’t have a plastic version of these.
