This one runs 21 feet along the rail and throws 8 feet of shade in a black Onyx vinyl canopy, backed by a matching black weathershield and black end castings. No motor, no wiring, just pull it out by hand. Mounting hardware is sold separately.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThe Dometic 8500 is the manual version of Dometic's long-running patio awning line, and it's the one a lot of RVers reach for when they want shade without wiring in a motor. You pull it out by hand. A heavy-duty torsion spring does most of the lifting, so deploying and stowing it is a quick job you can knock out on your own before you've even leveled the coach. This model, the 848NR21.300U, gives you a 21 foot rail length with an 8 foot extension, dressed in a black Onyx vinyl canopy with a matching black weathershield and black end castings.\u003c\/p\u003e\n\u003cp\u003eThat 21 foot span covers the full patio side of most travel trailers and larger fifth wheels. The 8 foot projection pushes the shade line well past your door and steps, so your chairs, grill, and dog bowl all sit in the shade instead of half-in and half-out. Because it's manual, there's nothing to blow a fuse or burn out a motor. It's just spring tension, a roller tube, and two rafter arms doing honest work.\u003c\/p\u003e\n\u003cp\u003eThe canopy is a 4-ply laminated, polyester-reinforced vinyl. Vinyl is the material you want if you camp in real weather. It sheds rain, it wipes clean, and it resists the scratches and abrasion that come from branches, road grit, and years of rolling and unrolling. The Onyx pattern carries on both sides, so it looks finished whether you're standing under it or looking down from the campsite next door. When you roll it up, the black vinyl weathershield wraps the stored fabric and keeps UV and highway grime off it while you tow. That cover is a big part of why these canopies last.\u003c\/p\u003e\n\u003cp\u003eUnderneath the good looks is hardware built to take abuse. The roller tube is a one-piece extruded alloy that holds its line across the full 21 feet without the sag you get from a lighter tube. The spring assembly is a heavy-duty torsion design running on self-lubricating bushings, so it stays smooth without you fussing over it. The end castings are die-cast and finished in black to match. Those castings live at the pivot points that see the most stress every time you deploy, so Dometic doesn't skimp there.\u003c\/p\u003e\n\u003cp\u003eSetting it up is a one-person job with a hand from a friend for the initial mount. Once it's on the rail, you slide a rafter arm up until it snaps into place, then pull down and out on the sliding rafter to take the slack out of the fabric. Tighten the black adjustment knob and you're done. The secure rafter lock system holds automatic tension, which is what keeps the canopy tight and stops it from flapping and drumming every time a breeze rolls through the campground. Vinyl cushioned lift handles give you a solid grip for deploying and retracting.\u003c\/p\u003e\n\u003cp\u003eOne thing to plan for. The mounting hardware is sold separately. Dometic does that on purpose, because RV sidewalls, rooflines, and mounting heights vary a lot from one build to the next, and a bracket kit that fits a flat-sided fifth wheel won't be right for a different coach. So before you order, figure out which Dometic hardware kit matches your rig, or check what your existing awning used if you're replacing one. The awning itself ships in carton packaging.\u003c\/p\u003e\n\u003cp\u003eA quick word on weather. This is a shade awning, not a storm shelter. It's under real spring tension, and it can roll up on you fast if you're not paying attention, so retract it before high wind or a heavy storm rolls in and never walk away with it out when the sky looks ugly. Treat it that way, keep the vinyl clean and dry before you roll it, and an 8500 will give you a lot of good seasons on the road.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003eManual spring-assisted operation, no motor or wiring to fail, deploy or stow it by hand in a couple of minutes\u003c\/li\u003e\n  \u003cli\u003e21 foot rail length with 8 foot extension, covers the full patio side of most travel trailers and large fifth wheels\u003c\/li\u003e\n  \u003cli\u003eHeavy-duty torsion spring assembly on self-lubricating bushings for smooth, low-maintenance roll-up\u003c\/li\u003e\n  \u003cli\u003eSecure rafter lock system with automatic tension keeps the fabric taut and stops it from flapping in a breeze\u003c\/li\u003e\n  \u003cli\u003e4-ply laminated, polyester-reinforced vinyl canopy in Onyx, waterproof, scratch-resistant, and colored on both sides\u003c\/li\u003e\n  \u003cli\u003eBlack vinyl weathershield wraps the rolled canopy when stowed to keep UV and road grime off the fabric\u003c\/li\u003e\n  \u003cli\u003eOne-piece extruded alloy roller tube resists sag across the full 21 foot span\u003c\/li\u003e\n  \u003cli\u003eBlack die-cast end castings at the high-stress pivot points for long service life\u003c\/li\u003e\n  \u003cli\u003eVinyl cushioned lift handles give a solid grip when you deploy or retract\u003c\/li\u003e\n  \u003cli\u003eShips in carton packaging, mounting hardware sold separately so you can match it to your RV sidewall\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\u003eIs this a manual or electric awning?\u003c\/summary\u003e\n    \u003cp\u003eIt's manual.
