User questions & answers

Question:	Can this be mounted on a wall
Answer:	Yes you can, apart from the sunlight angle
Question:	Does it have a screen to keep insects out
Answer:	We do not carry a screen at the moment
Question:	How do I get a/c Add on
Answer:	Please call us for the ac power kit
Question:	How do I calculate the wattage of a solar attic fan
Answer:	Watts are the result of multiplying the operating voltage times the draw max current. (W = E x I). Your operating voltage on an AC fan is 120 volts. The operating current is posted on the manufacturer's label on the fan. Multiply one by the other and you get your watts. On a DC system like solar or batteries the voltage is the max output produced and the current (I) is also on the label.

User questions & answers

Question:	Is there an option to purchase the cap without the entire assembly
Answer:	There were 30.
Question:	Are these china made crap. I bought three from ppl rv and in 60 days they broke apart like cookies from the arizona sun .biggest waste of money
Answer:	This is a different product that we designed to specifically combat blisters and chafing. It's a small strip of non-flexible tape that is breathable, synthetic, very strong, and very sticky. It's very different from our stretchy kinesiology tape.
Question:	What is the difference between the 40433 nd
Answer:	I did not hike through streams but I did leave then on through showers and I got at least 2 full days out of them. Much more resilient than bandages and absolutely much more blister prevention than anything I’ve used. They are extremely light weight. You could carry 10 in your wallet with nary a bulge.
Question:	Does this cover work with a fantastic fan
Answer:	Medium

User questions & answers

Question:	Will rain get in your RV
Answer:	push button. I have never had to use it, though - it is a pretty large display
Question:	Does this fan close off outside air from coming in when not in use? With Lou res
Answer:	It should be fine for checking the temps, but I’d probably stick to a glass thermometer that I could leave in the pot for making hard candy. The -robe of this thermometer would be fine, but I wouldn’t want to rest the body on the side of the pot for any extended period of time.
Question:	What is the working amp? i know is 12 v but need to know the amps
Answer:	I haven't dropped mine yet but it is water proof and I rinse it under running water after I'm done so I would think so.
Question:	what is the height from roof to top of the dome
Answer:	Yes these can be used underneath a glove. They may not last for extra days on your skin, but you would have some protection.

User questions & answers

Question:	Does this cover fit over a 14in dome and can I still open the dome from the crank inside
Answer:	The Camco vent cover that I purchased was for a replacement for one of the vent covers originally installed on my trailer in 2008. I would consider a 10 year life span especially in the hot southern sun more than acceptable.
Question:	does it come with the brackets and screws
Answer:	# 40431 has a front vent that's can removed for cleanup inside
Question:	How well will stand up to hail
Answer:	No it won't. Because the fantastic fan is electric it will open all the way or until it comes upon an obstruction, which is what will happen with this cover. It is not tall enough to let the cover open all the way. There are special covers for Fantastic Fans called Fantastic Vents. Amazon offers one in white with a number UB 1500WH but if you want one in smoke or black you may have to go somewhere else. I bought my black one at Camping World. The sell online too.

RV Roof Vent Cover

Camco RV Roof Vent Cover is designed to allow fresh air ventilation and light into your RV, rain or shine. RVs can get pretty stuffy when they’re all closed up, but having a constant flow of fresh air through the cabin will help keep the RV feeling and smelling fresh. The aerodynamic cover offers high flow ventilation with a design that allows you to keep it open when it’s raining, or even when you’re traveling. It is easily installed with included mounting hardware by mounting to the existing 14 inch x 14 inch roof vent. Vent cover made of rugged UV stabilized resin with removable louvers for easier cleaning. Available in five different colors.

How it Works

The Camco Roof Vent Cover installs over your RV Roof Vent, allowing you to open your roof vent during rain or shine and without impeding air flow. The removable louvers allow you easy access to your roof vent for maintenance and cleaning. For installation you will need a pencil, a drill with a 3/16 inch bit, a Phillips head screw driver and a crescent wrench. The rest of the materials are included with the product. To install the Vent Cover, first center it over your roof vent with the louvers facing the rear of the RV and mark the location of the slots with your pencil. Lay the mounting bracket on the roof so that the slot intersects one of the marked locations that are closest to the corners of the vent frame. Mark the locations of the screw hole in the vent bracket onto the vent frame and drill through the frame using the 3/16 inch diameter drill bit. Place one of the carriage bolts up through the bracket slot and fasten the bracket to the roof vent and frame using a #8 screw, washer, lock washer and nut which are provided for you. The washers and nuts will go on the inside of the vent frame. Install the other three brackets in the same way. Once all four of your brackets are installed, place the vent cover over the four carriage bolts and attached with the ¼ inch washers, lock washers and nuts. Before you tighten it, make sure the square heads of the carriage bolts are seated in the bracket slots to prevent them from turning. Do not over tighten. There will be a gap between the vent and your RVs roof- this is normal and will help prevent condensation. Your RV Roof Vent Cover is now installed and ready for use!

User questions & answers

Question:	Do any of the vents have a built in flapper to keep wind from entering
Answer:	This cover fits over my 14"x 14" bathroom vent. I believe the vent is a standard size. I have two other vents this size (14"x14") in my 5th wheel trailer. I can crank the vent in our bathroom about 3/4 of the way open. The vent opens and closes normally in all respects. The Camco vent cover comes with stainless steel brackets and screws to attach it to the vent. It is fairly easy to install. Dave
Question:	Do any of the vents have a built in flapper to keep wind from entering
Answer:	yes, it comes with brackets and screws. You will need a drill to mount the brackets to the aluminum frame of the vent, hand tighten everything, then snug them down with small wrench, screwdriver.
Question:	Is the finish painted black (as shown in picture) or is it natural aluminum finish? I suspect this is aluminum with no paint
Answer:	Only if hail is less than 4 inches in diameter. What I did is put aluminum sheet metal on top of it. It works great but it makes a lot of noise when it hails or even rains. I should have used 1/4 inch sheet metal instead of aluminum
Question:	how is a 6" round duct connected at bottom
Answer:	I ordered one to first check the fit of my three vents. The two fantastic vents would not fit but the bathroom stock fan vent did so that's where its installed. Works great no problems after two years.

BROAN Roof Mounted Attic Ventilators, 120-Volt

Powerful and easy to install, these units supplement or replace air conditioning by removing the blanket of hot, trapped air from attics.

Too often, attic ventilation is overlooked, not to mention ignored as a place for energy savings. That’s where Broan solutions make sense. Consider this: air trapped in the attic can easily reach 150-degrees or more. With Broan ventilation solutions, it’s still a full 60-degrees cooler in the attic on a 90-degree day. That’s why attic ventilation is critical to making any home more comfortable while lowering energy costs. Air conditioners can run less and won’t have to work as hard. Humid, stagnant air can be removed, drawing fresh dry air across the surfaces. Attics can be drier and cooler – the perfect tools to help fight potential moisture damage.

Available in three popular performance ratings. Select one that best suits attic size and shingle color.

Question:	Can this be used to vent a cooktop hood
Answer:	I had to return this item as the photo shows a 7" round outlet for exhaust on top but the item had no such outlet. I purchased the correct unit from another source and it has the outlet, round 7"
Question:	Can this be installed on a new residential steel roof
Answer:	No, it does not require a power cord. You have to wire it in to the existing connections.
