    Great Product

    I was so grateful to find these online. My outlets are from the 1950s and nothing in the box stores fit. These fit perfectly and look great! They came quickly too.

    Switch plate

    These are exactly what I needed. The only complaint I have is that I miscounted how many I needed and ended up one short! I would definitely order again

    surprisingly good quality

    I was quite frustrated when after painting my house I realized that the cover plates I'd assumed were $0.27 decora plates I could get at the big box were actually the slightly different shaped sierra electric plates. I was even more frustrated when I discovered that these were very difficult to find. I put off the purchase for over a year hoping I'd find something cheap but finally bit the bullet on these. I figured these would be just like the cheapies from the store and that I was paying a huge markup for them being a strange size that has to be custom made and stocked, but I was pleasantly surprised by the product I received. These are a quality metal cover plate with really high quality finish that I couldn't scratch with screws or chip by dropping -- even if it had been a standard size it feels like they can justify the price. Each plate came packed with its screws in a very tidy paper envelope and the lot of them were shipped in an appropriate sized box (not shipped in bubble envelope or in a huge box full of packing) It felt like every point in the process Kyles exceeded my expectations.
    They made a year long frustrating home renovation experience end on a positive note.

    old style sierra plates

    they were a perfect fit. If you have old plates from the 70s that have 3 plugs, these will work perfect.

    Glad to have found a replacement

    Construction workers disposed of our existing cover plate and no hardware stores carried them anymore. Thrilled to find a replacement here that fits perfectly, is reasonably priced, and good quality...not cheap plastic. Thanks for offering discontinued products!
