1 Pack - Boat Vent Cap 2 for Boat Cover

Order was as seen in photo but missing the reinforcement fabric for the underside. Product is great overall just beware that you will need a 2 1/2" circle to cut out for the vent. This hole must be exact so you don't cover the vent holes and not to big or it will continue to tear the cover. Quick and easy install, hardest part is figuring out where you want to put them. This will do the job it says it will and no more mold when you take the cover off.

Worked like it should.

Easily install work perfectly. Mark where you want to have the whole that accompanies the boat cap vent and I used chalk that worked well a sharp pair of scissors will help don't get over ambitious with the h o l e.

Liked price and shipping all was fine used it for pontoon cover pole

One of these flew off during a multi-state tow from our 2019 Malibu cover. I'm sure it was our fault for not ensuring that it was screwed on tightly before the trip. This is the exact replacement for what was there.

I bought this to repair my cover where a rear support pole ripped thru. Since you have to cut your cover anyways installing these vents it accomplished two things at once for me. Like another reviewer said, the bottom of a plastic solo cup is the exact circle cutout you need (2.25" in diameter). If you actually lookup the manufacturers instructions its those exact dimensions too. That hole size is needed so the vent part can be unobstructed when installed. Essentially there are 3 parts: the top, bottom, and the nut/washer. The top goes on the outside of the cover, the bottom goes on the underside of your cover and the nut/washer tightens it all down. Worked perfectly and now my cover is repaired/better than before. Also be aware that there is a Version 3 of this for covers that don't have reinforced areas on the cover. Version 2 (this one) is for reinforced covers only.

I had purchased this from sail rite before and these are identical at half the price from sailrite
