  • Simple fix for a tricky light mounting problem. Simple fix for a tricky light mounting problem.
Size: MEGA
First, this is a review for the siding plate from a resident of Canada. It is exactly what I needed to cover an Arlington octagonal square box. The original Arlington square housing was impossible to remove because it was extending in all directions under the siding of the house. No Canadian DIY outlet could get what I wanted to remedy my light mounting problem (light base was too large for standard square box).. Amazon.ca was $80 bucks for this thing. Amazon.com was $20. Shame on you Amazon.ca retailers, good for you Amazon.com retailers. Fits over the Arlington octagonal box to provide a solid backplate for light fixtures that are too big for the original electrical housing on the side of your house. It is basically a plastic cover that will fit over the Arlington octagonal (square) electrical box.It prevents water from getting behind the siding while providing a stable and attractive backplate for your light fixture. You can paint it any color using the same paint as your siding or trim. Note: It will fit over almost any square or octagonal box that has dimensions smaller than this plate. You may have to "McGuyver" the mounting screws, but it should work. ... show more

  • Perfecto
Size: MEGA
When my stucco house was built the electricians surface mounted round pancake boxes on either side of my garage door for the light fixtures. Unfortunately the fixtures would not fit flush against the wall and mud daubers would get in and built their nests. The gap was too big for caulk. The mega plate worked out perfectly. I didn't even screw it in place. Just placed in over the pancake boxes, remounted the lights and caulked around the plate and stucco. They're nice and strong also. The long dimension really helps when you have a fixture base that is not square or round. ... show more

  • Just what I needed!
Size: MEGA
I am a woman and installed this myself. Very easy. So excited that there is a product like this as the light I have been wanting has a larger backplate than siding block that was on my house. I wanted to make sure I could seal around the light. I have Hardie Plank siding.

  • Solved my little wall box issue Solved my little wall box issue
Size: MEGA
This sorta solved my issue by just placing it over an existing smaller box on my siding, something to note, there is a larger end of this product its not equal distances on each side. But did the trick for me.

Had to change out very old lights on front porch. The base is a lot bigger than the old lights. I just took of the old trim from the old base and screwed the new bigger base the old mounting block...PERFECT! looks great and really adds to entrance. Huge difference between the new and the old! The price is good too! ... show more

  • Well Designed and Industrial Strength Plates do Great Job Covering Small Siding Blocks
Size: MEGA
I now own 7 of these Siding Plates. I found that I needed them after purchasing some new fixtures for outside. The base on the new light fixtures were bigger than the siding blocks that I had. I looked around for new bigger siding blocks and found these. What I love about these is that they go right over the top of the old siding blocks. This means that you don't have to worry about the spacing and pitch of your siding. Additionally, they look great. In fact they look better than the siding blocks they are hiding. The bottom line is that these well designed industrial strength siding plates more than do the job and they look great doing it. ... show more

Needed a longer base for the outdoor light. This worked very well.

  • Mount hole
Size: MEGA
This wall plate is large enough for my large light plates. But the hole to access the wires should be left to consumer to cut where they need it. The access is large and if you have a narrow width light plate, it might not cover large hole in the middle of the mount.
