Review on Camco 40133 Replace All Plumbing Vent Kit (Beige) by Tyler Cooley

Spring clips snap firmly into the inner walls of 1.5" ABS tubing. I checked the pull force and the corners of the spring clips act like notches digging into the plastic making the cap very difficult to remove. really dig in. The only weak point I see is how the spring clip attaches to the underside of the plastic cover. I'm pretty sure it will work fine for a few years, but the mount isn't very secure (no mount, not molded) so I wouldn't be surprised to see a bare spring clip sticking out of a roof vent after a long drive . Overall good value for money and easy installation.
