Rated 3.2 out of 5 by 5 reviewers.
Rated 5 out of 5 by metal is stronger than plastic Read other reviews where they were concerned about the opening fitting a 4 x 4 post. Believe the opening is fine the way it is, just use your hammer to tap the plate level with top of post, it will fit, then run the screws into the sides of post...substantial. Metal sure beats plastic. This is a great accessory and easy to use. Allows for various types of attachments. Great design! June 19, 2012
Rated 5 out of 5 by easy to install, good price I liked this product because it was a good price and made sturdy. I needed something to hold up the weight of a large locking mail box and this bracket gets the job done. Fits snugly on the 4x4 post with some a few taps with a mallet. September 28, 2012
Rated 1 out of 5 by Would not fit I was elated to find a metal mounting bracket for my mailbox because I am tired of replacing the plastic ones. I also like the idea that the mailbox bottom would mount directly to the top of the bracket instead of using side bolts as on the plastic brackets. The packaging stated that it would fit a standard 4X4 wood post which is what I have. The inside dimensions where the bracket would mount to the post are only 31/2"X31/2". Needless to say that after mounting the mailbox to the bracket, I was totally disappointed that the bracket would not fit the post. Back to the plastic bracket. January 19, 2011
Rated 4 out of 5 by Does the job with a little alteration When I saw this product I was glad to find a durable product, with universal holes, at a reasonable price. When I purchased the product and took it home to assemble with my mailbox and 4x4 post I was disappointed that the post hole on the mount was not quite big enough to fit around my 4x4. This was easily fixed by using some plyers to bend the post brackets back slightly. It now fits perfectly and is creating a very stable base for the mailbox; however, I wish it would have fit correctly without any alterations. March 27, 2012
Rated 1 out of 5 by Doesn't Fit Fit the mailbox fine, opening is too small for a 4x4 post, pretty much the entire reason for buying it. May 3, 2012
