    Thank you!

    Searched everywhere to these outlet covers for my “vintage” home. Fit perfectly and arrived in a timely manner and packaged very well.

    Super find

    These things are for a kind of outlet that was apparently popular only for a small number of years: outlets with THREE two-prong plugs in them. Our otherwise awesome midcentury house has these. Overall these outlets are a huge pain, not least because no one sells the face plates. It was such a great thing to find a place to get new ones!

    Fit perfectly

    These hard to find outlet plates fit perfectly and I was pleased to see their heavy duty construction.

    Who would have thought my house was vintage : D

    Thank you Kyle Switch Plates. Never thought that a hardware store wouldn't be able to replace my cracked switch plates. Also never thought that they would consider a house built in 1961, vintage. But dimensions have changed in newer houses and it was impossible to find replacement switch plates. The guy at the hardware store told me about Kyle Switch Plates. So glad he did. The company helped me to find what I needed. They were so helpful and knowledgeable. I couldn't find what I needed myself, searching their website. So I called them. WONDERFUL. They found what I needed, and actually sent me a link to vintage plates, in case I would need to replace other plates in the future. Great company. They will be my go to place in the future.

    Minor purchase, major satisfaction

    I love the precision in specifying the measurements, helped assure me in choosing the right product *which fit perfectly!(.
    Delivery was punctual and the reminder to not lose the screws provided was a nice touch.
    I don't anticipate needing much more from this company but most definitely had a good experience and would not hesitate to patronize if the future holds some surprise!

    A perfect fit

    After searching for a new cover switch plate to replace one that had broken and finding that the ones in stores didn't fit, I found the Kyle Switch plates designed for my specific outlet.
    The cover fit like a glove and we're not talking O.J. Simpson glove here!!!
    It's perfect.
    Thanks so much!!!! It's good to know you're out there for those hard-to-find plate covers.
