  1. Who would have thought my house was vintage : D 5 Star Review

    Posted by on 26th Jun 2019

    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.

  2. Minor purchase, major satisfaction 5 Star Review

    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!

    Thank goodness for Kyle’s Switch Plate - had the cover plate I needed in my home I purchased. Excellent quality, fast delivery. Thank you! In my contacts if I need anymore hard to find “vintage” items.

  4. A perfect fit 5 Star Review

    Posted by on 18th Jun 2018

    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.
