3" Round Plastic Vent - Black - Package of 4

Used in camping trailer. They were perfect for what we needed.

I purchased these to install on the wall of a garden tool bump out following an example recently seen in the Family Handyman magazine. It provides adequate venting within the 4ft wide by 8 foot high bump out. I placed it high on the 16 inch wide side wall and drilled a 3inch hole using a hole saw. The siding was cedar and it fit a bit loose (probably due to my hole saw technique). A dab of construction adhesive on the inside between the vent and the siding did fine and it sits securely in place doing its job.

These arrived exactly exactly as described and are of excellent quality and easy to use! I made a homemade enclosure for my bearded dragon and used these for the air vents. Very happy that I chose these!

Great for adding a vent wherever. Installation is somewhat difficult unless you have a drill with a 3-inch diameter saw bit.

I think this is my 3rd or 4th order. Use a hole saw of appropriate diameter. My other orders used these vents in a rolling tool case used to house a 100 amp hour battery, solar controller, power inverter, battery isolator and a few other things for a home made solar generator.This set was used to vent a Keter tall outdoor storage storage shed with solar panels mounted to the roof and the rest of the solar generator inside the shed. It recharges the various batteries associated with yard/lawn maintenance items (blower, string trimmer, lawn mower) and drill.The vents work well to keep the summer heat at a manageable level in the shed. They are easy to install and the black color look great with the gray shed color.

Ordered these with a 3" Hole saw. They fit into the hole perfectly snug. Seem built well and will hopefully help keep my chickens from overheating in their coop.

Used these to add more ventilation to my corn snakes' pvc enclosure and they worked perfectly. Used a 3" hole saw bit and these popped right in the holes with a nice snug fit.

Got this for my Bearded Dragon's Cage to add ventilation. It fits snug in the 3in holes I cut with a 3 in hole saw. Will be ordering more as I want to cut more holes.
