  1. 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.

  3. 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.
