ProGuard Pre-Assembled PEX Stub-Out Kit - (1) SB3 Bracket, (2) #734 Turn-Out Supports

These kits are neat, easy and a very fast way to terminate pex under a sink or behind a toilet. Prefer this route for stub outs as the crimp ring is not buried in the wall and easy to either obeserve or fix a leaky crimp or end stop in the future if ever needed. I have screwed up (using pliers) and over tightened the white plastic nut behind the bracket that locks the bracket to the mounting strap and locks the angle of the bend support. But easy to fix with acouple of self tapping screws through the metal braket and two halfs of bracket. Once done, everything is tight and locked in and you are good to go.

"Works with all PEX". Apparently that mean works with PEX-b only. Because I'll tell, PEX-a will NOT fit. You damaged the pipe coating trying to push it through. The bend radius is so tight that it kinks the pipe trying to get it far enough over to push into the trough (which is never impossible). The biggest failure is that the front nut will NOT fit. The pipe pushes the tabs too far apart that the nut cannot engage the threads. The ONLY way to get the nut started is to use pliers and peel off the lip of 1 of the 3 tabs (at least the plastic does peel easy instead of snapping). This leaves the pipe askew when tightened but is better than loose by removing all 3 lips. So can PEX-a work? Yes, but not with modifying the clamp and damaging the pipe. Holdrite really needs to try their product before releasing it. The video shows the pipe sliding right through and the front nut easily hand tightened. Must be PEX-b cause you will not get that with PEX-a. Use at your own peril.
