Double-sided vinyl fabric, an anti-slack rafter that holds tension on its own, and an automatic rain shed that keeps water from pooling. Rolls out by hand for full-length shade on larger trailers and fifth wheels. Hardware is sold separately.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eThe Dometic 8500 Manual Patio Awning is the classic roll-out shade that a lot of travel trailer and fifth-wheel owners still ask for by name. This is the 21 foot version in Onyx, a double-sided vinyl fabric paired with a Polar White vinyl weathershield and Polar White end castings. It rolls out by hand, sets up in a minute or two, and gives you a big stretch of shade along the side of the rig without any motors or wiring to worry about.\u003c\/p\u003e\n\u003cp\u003eAt 21 feet of nominal rail length with an 8 foot extension, this is a full-length awning built for larger trailers and fifth wheels. That's enough coverage to shade a couple of camp chairs, the grill, and the entry door all at once. The fabric is heavy-duty polyester-reinforced vinyl, and because it's double-sided you get the Onyx look from underneath and from the campsite next door. It's UV-treated and scratch-resistant, so it holds its color through a lot of sun.\u003c\/p\u003e\n\u003cp\u003eWhat makes the 8500 easy to live with is the hardware design. The anti-slack rafter pivot keeps tension on the fabric automatically, so you're not out there re-cranking it every time the temperature swings. The automatic rain shed builds a slight pitch into the awning as it extends, which lets water run off one end instead of pooling in the middle and stretching the fabric. One person can roll it out and back with the pull strap and support arms. No second set of hands needed.\u003c\/p\u003e\n\u003cp\u003eOnyx is the darker, richer fabric option in the 8500 lineup, and the Polar White weathershield and castings give it a clean two-tone look that works on just about any coach color. The weathershield is the vinyl cover that protects the rolled-up fabric while the awning is stowed and you're rolling down the highway. Polar White is the neutral that matches most modern RV trim.\u003c\/p\u003e\n\u003cp\u003eOne thing to know before you buy: the hardware must be purchased separately. This part number is the roller assembly and fabric, the piece that wears out or gets damaged first. The mounting arms, brackets, and hardware kit are sold on their own. If you're replacing a fabric or a full roller on an existing 8500 setup, your current arms and brackets carry over. If this is a fresh install, you'll need the matching hardware kit for your rig's length. When in doubt, give us a call before ordering and we'll help you sort out exactly what you need.\u003c\/p\u003e\n\u003cp\u003eThis is a manual awning, so there's no power switch, no wind sensor, no motor to fail. You extend it with a crank or pull strap, drop the support legs, and adjust the pitch by hand. That simplicity is the whole point. Fewer parts, less that can break, and an easy repair when something eventually does. It's the reason the 8500 has stayed in service on so many trailers for so many seasons.\u003c\/p\u003e\n\u003cp\u003eSetup at the campsite is quick once you've done it once. Extend the awning to the pitch you want, lock the rafters, and set the support legs either down to the ground or up against the side of the RV depending on your site and the weather. Bringing it in is the same steps in reverse. A quick word on care: rinse the vinyl with mild soap and water now and then, let it dry fully before you roll it up, and don't store it wet for long stretches. That's most of what keeps a vinyl awning looking good for years.\u003c\/p\u003e\n\u003cp\u003eGood fit for anyone running a larger travel trailer or fifth wheel who wants dependable shade at the campsite without the cost and complexity of a powered unit. Roll it out when you set up camp, and always bring it in before you leave the site or any time the wind kicks up. Manual awnings don't retract on their own, so it's on you to stow it. A gust against a fully extended 21 foot awning puts a lot of load on the arms and the RV wall, and that's the single most common way these get damaged. Roll it in, and it'll last.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003e21 foot nominal length with an 8 foot extension covers the full side of most larger travel trailers and fifth wheels.\u003c\/li\u003e\n  \u003cli\u003eDouble-sided Onyx vinyl fabric looks finished from below and from outside, with UV treatment that holds color in the sun.\u003c\/li\u003e\n  \u003cli\u003ePolar White vinyl weathershield wraps and protects the rolled-up fabric while you travel.\u003c\/li\u003e\n  \u003cli\u003eAnti-slack rafter pivot keeps the fabric tensioned automatically, so there's no re-cranking as temperatures change.\u003c\/li\u003e\n  \u003cli\u003eAutomatic rain shed pitch lets water run off one end instead of pooling in the middle.\u003c\/li\u003e\n  \u003cli\u003eOne-person operation with pull strap and support arms, no second set of hands or power needed.\u003c\/li\u003e\n  \u003cli\u003ePolar White end castings give a clean two-tone finish that matches most RV trim.\u003c\/li\u003e\n  \u003cli\u003eHeavy-duty polyester-reinforced vinyl construction stands up to seasons of outdoor use.\u003c\/li\u003e\n  \u003cli\u003eFully manual design means no motor, wiring, or wind sensor to fail, and an easy repair when needed.\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\u003eDoes this awning include the mounting hardware?\u003c\/summary\u003e\n    \u003cp\u003eNo. This part number is the roller assembly and fabric only.
