Dometic K1301-10 Fan-Tastic Vent Screw Kit

If you're pulling an old Dometic Fan-Tastic Vent off the roof, or setting a fresh one down into the opening, you need the right hardware to put it back solid. This is that hardware. The K1301-10 kit gives you all 22 screws Dometic calls for on the job: 18 to mount the vent and 4 garnish screws for the interior trim ring. No guessing at the hardware store, no mismatched threads backing out six months down the road.

The 18 mounting screws are what hold the vent's flange down to your roof. A Fan-Tastic Vent drops into the standard 14 inch by 14 inch cutout, and those screws run through the flange perimeter into the roof deck. Get them all in, snug them down even, and the vent won't rock or lift when you're rolling down the interstate at 65. Lose a few over the years to rust or a rough removal and you've got a vent that leaks or buzzes. This kit puts a full set back in your hand.

The 4 garnish screws do a different job. Inside the coach, the garnish is the trim ring that frames the opening and hides the raw ceiling cutout. Those 4 screws thread up into the fan base from inside the RV and pull the garnish tight to the ceiling. It's a clean, finished look, and it's what keeps the interior trim from sagging or rattling loose over a season of travel. Four is exactly what one vent needs.

Keep the two screw types sorted. The mounting screws and the garnish screws aren't interchangeable, and swapping them makes for a loose vent or a stripped garnish. The kit keeps the count right for you: 18 for the roof, 4 for the trim.

So who's reaching for this kit? Anybody resealing a roof and lifting the vent to get underneath it. Anybody replacing a cracked garnish or a tired old vent with a new one. Anybody who bought a used rig and found the previous owner's mystery screws stripped or missing. And anybody doing a fresh install who'd rather start with the manufacturer's own hardware than a fistful of deck screws. Matching screw length and thread matters more than folks think. Too long and you punch through something you didn't mean to. Too short and the vent works loose. The right kit takes that worry off the table.

A word on the install itself. When you set the vent back down, you're relying on a bed of sealant under the flange plus these screws to keep water out. Screws alone don't waterproof anything. Lay your butyl tape or putty under the flange, run the 18 screws down snug and even, then top the heads and the flange edge with a self-leveling lap sealant rated for RV roofs. Do the garnish last, from inside, once the roof side is buttoned up. That order keeps everything square and gives you a dry, quiet vent.

The Fan-Tastic Vent has been a go-to powered roof vent in RVs and campers for decades, and Dometic keeps the replacement hardware flowing so an older vent stays serviceable instead of landing in the scrap pile. Keeping a kit like this on the shelf is cheap insurance. When you're up on the roof with the old vent already loose, the last thing you want is to find out you're four screws short.

It's a small part. But it's the small part that keeps a good vent sealed and solid for another decade. For what a full set of matched screws costs, there's no reason to trust a leak-prone roof to whatever's left in the coffee can. Grab the K1301-10 when you're due for a reseal or a swap, and you'll have exactly what the job calls for.
