It's magnetic, so it seats flush and won't rattle loose, and the bayonet lugs let you clip your hose right to it. Grab the cap, pull, and your hose slides out clean.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eIf you store your sewer hose in your RV's rear bumper, you already know the weak spot. The open end. The Camco 40311 is the magnetic cap that closes it off, and it does one more thing that actually matters day to day: the bayonet lugs on the face let you clip your sewer hose fitting right onto the cap. So the cap becomes your handle. Pop it off, pull, and the hose comes with it.\u003c\/p\u003e\n\u003cp\u003eHere's the setup it's built for. A lot of travel trailers and fifth wheels come with a hollow 4-inch square steel bumper across the back, and that tube is the perfect place to stash a sewer hose out of sight. The catch is keeping the hose in there and keeping the end sealed. This cap fits on the end of most metal 4-inch square bumpers, and the magnet holds it tight against the steel so it doesn't work loose while you're rolling down the interstate.\u003c\/p\u003e\n\u003cp\u003eThe bayonet lugs are the part people don't expect. They're compatible with any Camco bayonet-style sewer hose fitting, so you twist the bayonet end of your hose onto the lugs and it locks in place. Now the hose is anchored to the cap instead of floating free inside the bumper. When you pull into a site and it's time to dump, you grab the cap, give it a tug, and the whole hose slides out clean. No reaching elbow-deep into a grimy bumper tube trying to fish out the end.\u003c\/p\u003e\n\u003cp\u003eThen there are the vent holes. They look minor, but they earn their spot. A sewer hose that goes into storage even a little damp will get funky fast inside a sealed tube. The vents let air move through so the hose can dry between trips and any odor escapes instead of building up in there. Over a full season of camping, that's the difference between a bumper you don't think about and one you dread opening.\u003c\/p\u003e\n\u003cp\u003eIt's molded from polyethylene, so it shrugs off road spray, UV, and the occasional parking-lot knock without cracking. The finish is black, which blends in with most factory bumpers instead of standing out. You're getting a single cap in a retail package, sized for one open end of the bumper. If both ends of your bumper are open, you'd want one for each side.\u003c\/p\u003e\n\u003cp\u003eInstall is about as easy as it gets. Slide it over the open end of your 4-inch square metal bumper and let the magnet seat against the steel. That's it. No brackets, no drilling, no tools. If you've been getting by with a tennis ball jammed in the end or a rag stuffed in there, this is the obvious upgrade, and it actually stays put. A quick tip from folks who run these: a light wipe of silicone grease on the lugs now and then keeps the bayonet turning smoothly so it never fights you at the campsite.\u003c\/p\u003e\n\u003cp\u003eA couple of honest notes so you buy the right thing. This cap is made for the square metal bumper style. If your rig has a round bumper or a molded plastic one, this isn't your part. And the grab-by-the-cap trick only works if your sewer hose uses Camco bayonet-style fittings. If it doesn't, the cap will still seal and vent the bumper just fine, you just won't get the quick-release handle feature.\u003c\/p\u003e\n\u003cp\u003eFor what it costs, the Camco 40311 is one of those small RV parts that quietly makes dump day less of a chore. It keeps your hose contained on the road, lets it dry out between trips, and hands you a clean way to pull it in and out. Set it and forget it, right up until you're glad it's there.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003eMagnetic cap seats flush against a metal 4-inch square RV bumper so it won't rattle loose on the highway\u003c\/li\u003e\n  \u003cli\u003eBayonet lugs attach to any Camco bayonet-style sewer hose fitting, so the cap doubles as a pull handle for your hose\u003c\/li\u003e\n  \u003cli\u003eVent holes let the stored sewer hose breathe and dry out, cutting down on trapped odors\u003c\/li\u003e\n  \u003cli\u003eMolded polyethylene shrugs off road grime, UV, and the occasional knock\u003c\/li\u003e\n  \u003cli\u003eBlack finish blends in with most factory RV bumpers\u003c\/li\u003e\n  \u003cli\u003eFits on the end of most metal 4-inch square bumpers\u003c\/li\u003e\n  \u003cli\u003eSlide-on install with no brackets, drilling, or tools\u003c\/li\u003e\n  \u003cli\u003eSold as a single cap in a retail package\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized Camco reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eWhat does the Camco 40311 do?\u003c\/summary\u003e\n    \u003cp\u003eIt caps the open end of a metal 4-inch square RV bumper that you use to store your sewer hose.
