Glad I found these!

We have replaced these parts several times with cheap materials from our local store. Seen these were offered and ordered them. They work perfectly in the spots, no trimming or removing the siding like with the others. It looks so much better now!
Plug and Play Replacement

Exactly what I was looking for. Tried home stores and was in the process of cobbling a larger plate and ran across this one. Install was a breeze. I wish the back was perforated to allow for easier removal of outlet opening but I was able to use a utility knife to accomplish the task.
Turned out fine.

Didn't seem to match the picture of what I ordered but handyman used it during porch light replacement. He had to trim a bit to fit. It looks very nice. Much better than the old trim box. Handyman was satisfied.

We could not find these mounting blocks anywhere! They fit in perfect . Didn't have to trim siding at all. Only had to cut out for electrical socket.
I looked all over for replacement and happened upon this site

Product was as described. Looks nice.
Vinyl siding mounting block

It is made of very durable plastic, the exact same size as the old one. The siding may have to be trimmed, but done easily with a razor knife or tin snips. I highly recommend it if your old one is cracked from weathering. I looked for hours and finally located this trim piece on this site. No one else has simple trim pieces that fit exactly or for sale. Thanks, Mobile Home Parts Store
Perfect Fit for my outlets and dryer vent

The mounting block 9\\\\"x9\\\\" appears to be good quality and just the right size to replace the blocks that are deteriorating from exposure to the sun and weather for the last 12 years. I'll need to order more as I replace the blocks for the coach lamps. I wasn't able to locate this size in any mobile home supply houses or box stores. Vinyl siding supply houses didn't have this size in their supplier catalogs either. The sales rep for the Mobile Home Parts Store, even retrieved one from the warehouse to get a depth measurement for me. Great people to work with.
