HG Power Soffit Vents 4 inch, Round Vent Cover with Built-in Screen Mesh, ABS Louver 4” Exhaust Vent for Exhaust Fan, HVAC Ducting, Bathroom, Kitchen, Garage Use, 100mm, White

Worked as expected and great price!! Cheaper than buying from Home Depot or Lowes.

It's all plastic. It works. Will last as long as plastic does.

Easy to install

Pros- Nice neat look, has screen built in to block pests, easy installCons- only 1, plastic the plastic tabs that are supposed to hold the vent in place are absolutely useless. Easy fix with 3 small flanged SS screws but this product would be perfect if it had 3 countersunk holes and came with 3 SS screws. Luckily between the combination of flexibility in the plastic of this product and the small flanged screws I used they almost laid flush, looked countersunk and held it up nice and tight. I wouldn’t suggest pre-drilling holes because I feel that a flanged or fluted screw would either go right through or be holding on by a thread. If it’s for somewhere you could care less about esthetics then drill small pilot holes and use three SS pan head screws..All in all.. for the price and easy fix of install.. it works, will be secure and comes out almost perfect if you use small.(think I used either #4 or 6) screws just make sure you use Stainless screws.Review from- a licensed MA. electrician that has installed hundreds of exhaust vents..

Just as described.

Worked perfect

this is the best one of these I have bought. What I like about it is that it has flanges for the vent to stay secure on my building.

...but both can be solved. The big one is that the spring tabs do not grip drywall, the only press against it. When attaching ductwork from the inside it falls out of the hole quite easily. Really problematic for ceiling applications.Here are some solutions: 1) Perimeter facial screws & sheetrock anchors (not pretty, but able to withstand a mild push). 2) A helper on the other side to push back when attaching ductwork. 3) Construction adhesive applied liberally around the base and the neck--requires a day or two to set up. 4) Cut the drywall at a sharp bevel to allow the spring tabs to open wider. Caveat: Rough handling can rip open the sheetrock. 5) What I did: used a right-angle, low-profile screw gun to drive three i-5/8" dry wall screws 1/2" into the perimeter of the duct neck at sheetrock level. Helper advised.The other problem is the inner plastic bug grill: Tight enough to thwart mosquitos or fruit flies, but a serious impediment to air flow. Once it gathers enough dust to clog, it can only be cleaned by removing the duct work from the inside--which usually involves cutting & replacing zip tie straps. My solution: trashed it. Alternate solution for accessible ductwork: improvise an in-line enclosure for a removable filter.
