- Reviewed in the United States on December 16, 2024Color: BlackVerified PurchaseWorks as advertised. I would purchase it again
- Reviewed in the United States on August 21, 2022Color: BlackVerified PurchaseThese RJ-45 keystone inserts are exactly as described.
They were packaged in 5 separate baggies containing 5 coupler's each. UL listing is on the product, as per the images and per ULs requirements. They're essentially plug & play with a 24-port patch panel, the one I chose was TRENDNet's 24-port Blank Patch Panel. The clips snap right in and align without any issues.
I can't really say much else, they're pulling their rated CAT-6 speeds and are smooth when you snap in your RJ-45 cables. If you're looking for good RJ-45 inline couplers then these are it.
- Reviewed in the United States on May 10, 2024Color: BlackVerified PurchaseEasy to install and remove. Use a small screw driver to push down on the clip and remove.
- Reviewed in the United States on February 14, 2021Color: BlackVerified PurchaseSee those other reviews with people claiming these are too fragile and they broke on installation and their thumbs hurt? I'm willing to bet they tried installing them the wrong way. So for those of you who haven't installed keystones before- here are a couple tips:
For installation:
There's a little tab at the bottom of the couplers in addition to the flexible clip at the top. If you try to force them in straight-on, something is going to break because there are retention mechanisms on bot the top and bottom. Instead you should put the keystone in at an angle so that little tab on the bottom goes in first, then tilt it forward into the proper position. Done right, it should easily click into place without force.
For Removal:
Apply pressure with your thumb nearest the face of the panel and tilt the back of coupler downwards until the top clip clears the keystone jack, then you can easily lift and and pull the rest of it out of the jack. I've removed them a few times and not had them break on me.
As for quality? I'd say they're decent. The fit is a little loose but not terrible. They arn't the more expensive full metal keystones, but they do perform to spec, support PoE, and the packaging has perforations for easy opening. (Thank you manufacturer) Overall I'm happy with the purchase, and didn't break anything installing 24 of them, removing a few and reinstalling them elsewhere on the panel.

Using them at 1G and 2.5G speeds without issue.
- Reviewed in the United States on December 4, 2017Color: BlueVerified PurchaseThese came in a ziplock bag with a quick-release open, and each connector was also individually wrapped in its own ziplock bag. Connectors appeared exactly as described. Although these are specifically made for keystone jacks, these are extremely convenient for combining multiple cables together in order to get a longer distance from two shorter cables. One reviewer made the comment that he could imagine these being too cheap for use when constantly plugging and unplugging cables. I don't have the experience of this type of failure to say one way or another if this is a valid concern, but I can definitely vouch for the fact that these are some great things to have lying around for someone who is just needing to get something done in the minimum amount of time and get back to the important work resulting from having a proper network connection in short order. A cheap $9.99 dremel tool from harbor freight can get rid of the keystone clip if you wanted to just have a cheaper female/female adapter.

- Reviewed in the United States on July 28, 2023Color: BlackVerified PurchaseMy first few attempts at inserting these into the Patch Panel failed because it seemed that these did not fit properly. However, after closely studying the fit, I realized it was simply blocking against the bottom tab that is supposed to be inserted inside the panel socket. As another post indicated (https://www.amazon.com/review/R1RF5ORDBM7FSG/ref=cm_cr_srp_d_rdp_perm?ie=UTF8&ASIN=B075ZPGV1H) I tipped the insert upwards to hook the bottom tab inside the socket, then leaned it forward to engage the top into the opening, and with a little jiggling, it snapped right into place. No breakage on any of the 24 pieces. Don't force anything or you WILL break something. It really does just snap right in once you have the bottom in. And it's an overall nice fit!
- Reviewed in the United States on December 30, 2020Color: BlackVerified PurchaseSome have complained that the tabs are too fragile and that they break. I installed 24 of these without a single issue. I wonder how much force others were putting on them because I definitely didn't muscle them in. I found placing the bottom half in first and then rocking the top part till the tab snapped in. It's not luxury, and there is definitely a small amount of wiggle, but welcome to manufacturing tolerances to accommodate other parts. I would definitely recommend this, as I think it fits the application.

5.0 out of 5 stars Fits my Tripp Lite (Shielded) Patch Panel
Color: BlackVerified PurchaseThe VCE In-line Coupler Connectors fit in my new Tripp Lite (Shielded) Patch Panel. I was concerned there may be an issue but the couplers snapped in without any problems. Also, my Platinum Cat 6 RJ45 Pass Through Connectors plugged in and stayed in. There wasn't any sloppiness in the connection that could lead to connectivity issues. So far, the patch panel with the VCE couplers is working very well.
As good as the couplers are, I took off one star since I thought the price point was a little higher than it should be. However, it is an excellent product and should I ever need to, I would still buy again.
