M-D Building Products87916 White Outlet Sealers for Standard & GFCI Outlets

Fits and seals better than other brands I have purchased. very pleased

They are so easy and simple, they're genius. I have a very old home and you can always feel cold air coming through the outlets. Not anymore! Only took about 2 seconds to install. It is literally the easiest, quickest fix ever, and I don't know why all outlets on outside walls aren't required to have these.

These will stop most of the draft coming from outlets. They don't stop it fully, but they can be installed very easily, as opposed to try and seal the electric box, or to replace it with an airtight one once the wall is finished.

Just the right thickness. (Some products of this type are so thick, you can't get the faceplate screwed back down flush with the wall again.) The bit in the middle is perforated, and can be punched out to make a rectangular opening to support Leviton's "Decora" style outlets (switches and receptacles).

It also says in the same warning in caps, DO NOT USE WITH DIMMER SWITCHES

i tried a cheaper version of these from another company, and they were ridiculously thick, so the outlet covers stuck out from the walls. went back to getting the M-D ones, which are well-made and easy to use. i got enough for my whole house and they work like a charm.

Great product for increased insulation at weak areas.

The best thing you can do to cheaply increase your home's efficiency. Easy to install and the it pays for itself almost immediately.

Work fine.
