If the fabric on your topper sags, flaps, or won't retract cleanly when you pull the room in, a worn torsion arm is usually the culprit. Genuine Dometic replacement, in black.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eIf you've got a slide-out on your RV, you've almost certainly got a slide topper over it, and the Dometic SlideTopper is one of the most common ones out there. The topper is that fabric awning that unrolls automatically across the top of your slide room as it extends. Its whole job is to keep leaves, rain, pine needles, and standing water off the slide roof so none of that debris rides back inside when you pull the room in. The torsion assembly is what makes that automatic action work. It's the spring-loaded arm on the end of the roller tube that keeps constant tension on the fabric, rolling it back up tight every time the slide comes in.\u003c\/p\u003e\n\u003cp\u003eThis is the left-hand version in black. On a slide topper you've got a torsion arm on each end of the roller, and they're handed, so a left-hand arm and a right-hand arm aren't interchangeable. Which one you need comes down to which side of the slide-out it mounts on. Stand outside facing your slide the way you'd look at it from the campsite, and the left end of the roller is where this one goes. If you're replacing a failed arm, the easiest move is to match the hand of the one that's coming off and match the part number on the old assembly.\u003c\/p\u003e\n\u003cp\u003eSo how do you know the torsion arm is the problem? A few tells. The fabric starts to sag in the middle instead of staying drum-tight. It flaps loudly in the wind because there's no spring tension holding it. Or the worst case, it doesn't fully retract when you bring the slide in, so the topper bunches up or the fabric drags. That's a sign the spring inside the torsion assembly has lost its tension or the mechanism has seized. When one arm goes, the fabric loads unevenly and the whole topper stops tracking straight. Replacing the tired arm brings the tension back and gets the topper rolling clean again.\u003c\/p\u003e\n\u003cp\u003eOne thing to be clear about up front. This is the torsion arm hardware, not the fabric. If your fabric is sun-rotted, faded, or torn, that's a separate replacement piece sized to your slide width. Plenty of toppers need both at once after years in the sun, so it's worth eyeballing the fabric while you've got everything apart. But if your fabric is still in good shape and it's just the tension or retraction that's gone soft, this arm is the fix on its own.\u003c\/p\u003e\n\u003cp\u003eIt's easy to think of a slide topper as a nice-to-have, but a working one actually protects the rest of your slide-out. When debris and water sit on top of an unprotected slide roof, that gunk gets dragged across the slide seals every time the room moves, which wears the seals out faster and can start letting water in. Keeping the topper tensioned and retracting properly keeps that junk off the roof in the first place. So a fresh torsion arm isn't just about the awning looking tidy, it's cheap insurance for the slide seals and the floor underneath them.\u003c\/p\u003e\n\u003cp\u003eInstalling it is a manageable job for a handy owner, but it helps to know what you're getting into. The torsion assembly is under spring tension, so you're working with a loaded spring when you remove the old one and set the new one. Take your time, follow the tensioning procedure for the number of turns your topper calls for, and have a second set of hands for anything above a small slide. Because this is a genuine Dometic assembly, it drops into the same mounting points and lines up with the existing roller and brackets, so you're not fighting a fitment that's a hair off. Black hardware keeps it looking right under a black or dark topper and matches the rest of the Dometic SlideTopper trim.\u003c\/p\u003e\n\u003cp\u003eWho's this for? Any RV owner running a Dometic SlideTopper who's chasing a sagging, flapping, or half-retracting slide awning. Fifth wheels, travel trailers, and motorhomes with slide-outs all use this same style of topper hardware. Get the hand right, confirm the part number against your old arm, and you'll have the topper back to doing its quiet, unglamorous, important job of keeping your slide roof clean and dry.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003eLeft-hand torsion assembly, sized to mount on the left end of a Dometic SlideTopper roller tube\u003c\/li\u003e\n  \u003cli\u003eGenuine Dometic replacement, part number 3315005.011U, drops into the factory mounting points\u003c\/li\u003e\n  \u003cli\u003eSpring-loaded design keeps constant tension on the fabric so the topper rolls up tight every time the slide retracts\u003c\/li\u003e\n  \u003cli\u003eBlack finish matches black and dark Dometic SlideTopper fabric and trim\u003c\/li\u003e\n  \u003cli\u003eRestores clean retraction on a topper that sags, flaps, or bunches up when the slide comes in\u003c\/li\u003e\n  \u003cli\u003eTorsion arm hardware only, pairs with your existing roller tube and fabric\u003c\/li\u003e\n  \u003cli\u003eFits the Dometic SlideTopper slide-out awning system on fifth wheels, travel trailers, and motorhomes\u003c\/li\u003e\n  \u003cli\u003eHanded component, order the left-hand version for the left end and match it to your old arm\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 Dometic 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 torsion assembly do on a slide topper?\u003c\/summary\u003e\n    \u003cp\u003eIt's the spring-loaded arm on the end of the roller tube that keeps constant tension on the fabric.
