Customer Questions & Answers

Hi is this post compatible with Gibraltar mailbox model #DM160V01?

Hi is this post compatible with Gibraltar mailbox model #DM160V01?
Asked by: Salad
Thank you for your recent inquiry. The Steel Drive-In Post Kit is constructed from heavy-duty galvanized steel with a black powdered paint finish. It features an adjustable mailbox support arm, which allows the mailbox to be adjusted to the proper height from the ground. The post accommodates standard size which is a T1. The Designer mailbox is a large size mailbox, considered a T2 and is not compatible with this post. We hope you find this information helpful.

Can you install this unit with concrete mix (as opposed to driving it into ground)?

Asked by: MemphisTinker
Here are some pictures, I poured the dry cement in first, then the post, then some water, and more mix. It stayed in place and was high enough, and it's very sturdy

How does this get placed in the ground? Do you bang it in with a rubber mallet?

Asked by: Mac
Depends a bit on how the hardness of your ground. We've had very little rain in a long time so our ground is hard. Had to use a sledge hammer hitting a piece of wood (so not to directly hit the metal). Even still, the top bent making it very hard to get the top half of the pole to slide down onto the bottom half. It's inexpensive, but I'd seriously consider using it on softer ground or waiting til it rains or use water to soften the ground before trying to put into the ground.

Rated 2 out of 5 by from Rusted and Broke After Only 3 Years - Good While It Lasted... Installation was fairly easy. The “sharp” (angle-cut) end was easy to drive into the ground. The mounting hardware was a bit awkward to assemble onto the box (which might be unavoidable since the post could accommodate several models of boxes with differing mounting holes). My complaint (and the reason for the review coming a few years after installation) is that the angled arm that supports the box broke off (dropping the box to the ground) when retrieving the mail after only 3 years of service. It was plain to see that the black paint (applied by the factory) provided insufficient protection from water and the parts rusted until they could no longer take the load. Now we may have to wait several days to discover how much we won in the Publishers Clearing House Sweepstakes. The box was installed roadside in eastern Massachusetts and was exposed to a modest amount of road salting during 3 winters. However, I think it is reasonable to expect considerably more than 3 years of service from a product of this price. It did look fine and work well until it broke, and it might well survive a lot longer in an arid climate (or at least where no salting is applied in the vicinity). Good luck! :-)

Post sits back further than most so the mailbox can be close to the road and allow the snowplow to have clearance without hitting it.

Rated 5 out of 5 by from Worked great in wet clay soil! This drive-in post was very easy to install into wet clay soil by a 55-year old woman, and it was surprisingly sturdy when driven 20 inches deep into the soil. The adjustable arm allowed me to mimic the height of the mailbox next to mine, which was however under the normal height of 41 inches. I especially like the fact that if the postman doesn't like the placement or height of my mailbox, I can easily move or adjust it. I attached it to Gibraltar's standard steel mailbox (E1100B00) using the undermount instructions and had no problem with the installation. I initially thought about using Gibraltar's Lincoln decorative plastic mailbox (PM000B01) but noticed that the side mounting holes did not exactly line up with the holes in the L-brackets provided with the post. However, I do think you could make it work by slightly adjusting the L-brackets. I was about to do that when I broke one of the pieces off the plastic mailbox, so I used the steel mailbox instead. All in all, I'm highly please with the ease of installation and the look and sturdiness of the product.
