How do they attach

Asked by Kevan3x October 18, 2020

Included in the package is a collapsible spring that is inserted into the front of the plate, then compressed with your fingers. The plate is then placed to block the vent with the spring set (as the directions explain), then inserted into the center hole in the existing foundation vent screen. The next step is to release the spring; presto, the vent cover is installed. The instructions are included on the package card.

How far does the hook on the spring reach when depressed

Does the crawl space still “breathe” with the vent on?

No. While not an "airtight" seal, they will certainly not allow any air "flow".

is it good to keep these on in the summer months

In the hot humid south, you don't want warm humid outside air to enter the crawl space and add moisture under you house. Many of us need a vapor barrier over the dirt in the crawl space to keep the moisture from coming up from the soil and it is bad for the moisture to enter into the crawl space through the vents. The warm humid air from outside cools under the air conditioned house and the air becomes more saturated and increases the moisture under the house and in the wood floor joists increasing mold and rot. From a moisture perspective, the moisture is so low in the cold months (winter) that keeping the vents closed is fine unless you need to vent something such as radon gas, etc. If you need to vent to get rid of radon or other gases or smells, you need an engineered plan with active components such as fans and / or dehumidifiers. In the hot humid south, it is better to keep the vents closed to reduce mold and rot.

Yes, they are easily removed and replaced but be aware that the metal is very thin and easily deformed. Take care when removing and replacing

This product worked for what I needed. For my application, I had to modify the edges by adding 1/2 inch wide by 3/8 inch deep strips of low-density foam window seal tape. This was needed to ensure a complete seal of the edges due to the irregular nature of the concrete skirt surrounding my house.

This product was minimally useful to me because the method of attaching it needed to be modified. I needed to buy wing nuts for use with the bolts already in cement foundation. The aluminum is thin, also. I will need to use foam or another insulator with the aluminum to ensure protection in near zero wind chill like we had last winter.

While this is a good buy. In my application I had to work with the spring a lot and in 50% had to rig up an alternative method to keep the cover in place. May be they could offer an alternative that uses more of a hook and screw approach.
