Parking lot sign base

Your review: The sign base is a good product for the price.

Pros: Stands up to a lot of abuse and strong winds

Cons: Needs slightly stronger plastic around neck where sign goes into base

Is this review helpful?

very disappointed

Your review: The bases do not hold the sign straight. The screw is merely in the plastic base and it does not hold the post in. The base is only a week old and is cracking in the post hole. It allowed rain to get into the base and it keeps leaking when brought inside at night. ***Customer Service has been appraised of the situation and they are resolving with the customer.***

Pros: no pros!

Cons: Plastic is not strong enough to withstand holding the sign post. Ot needs a better design like gluing PVC pipe in the center opening to make the hole more solid. I am now looking for new bases for my beautiful signs so they will stand up straight and not bend. Do yourself a favor and look for something else!

Parking Lot Sign Base

Pros: Easy to assemble

Cons: Thought there would be more than 1 bolt tieing post to base.

sign post base

Your review: This is a great base but it only has a 1" hole in it for the sign post. Most sign posts are 2", so I thought this would be a 2" sign post base. I was wrong and no information was given on size. Now what will I do with it??

Pros: Nice base

Cons: Only has a 1" pole base...

Poor quality control

Your review: I ordered 5 of these for portable signs at work. Only 2 of these were ready to go and 3 needed modification to be workable. Half of the tubes had the holes drilled off set. In other words, to mount posts they needed to be drilled again (on the opposite sides). The screw that mounts the tube had plastic molded over the top on 3 of them. Had to cut that part off to even unscrew them.

Pros: - Cheap - Once modified, seem to be holding up alright so far

Cons: - Poor quality - Seemingly no quality control - Not very sturdy - Even though they are cheap, you don't get what you pay for

Parking lot sign post base

Your review: Product works great. No problems.

Not good for it's intended purpose

Your review: This product is way to flimsy to hold the sign post and sign under most any real world outdoor situation. I had already filled them with sand and installed them in my parking lot before I realized that they were more of a liability than anything. I threw them both away and will put the sign posts in a concrete base. What a waste of time and money!

Good Value

Your review: Good price, easy to install, works well...not for heavy duty applications

Parking lot sign post

Your review: Serves it's purpose but Screw on plastic does not work well. The screww went right through the plastic and therefore the steel post is not secured tightly.

Sign Post Base

Your review: Not quite what I expected. The base is very flimsy and the single bolt to hold the tube inside is inadequate.

Base works well for the job

Great product

Your review: Great design and light weight. It was perfect for what we needed. Wanted a sign in an area with limited wall space and floor made of grating.

Portable Sign Base

Your review: This base works well the NO PARKING SIGN it holds gets moved several times daily for deliveries and is constantly dragged on the black top with little signs of drag ware. It comes empty and you can fill with sand, small stones or water. This allows you to adjust the weight of it to match (how windy) the ability of those who have to move it.

Leaks like a sieve

Your review: I liked the portablility of these posts. we needed that at the church. We had brought them in one night and they leaked all over the carpet, With two leaking sign bases, it was a lot of water. It is important to say that the company has been very helpful. I am waiting for the credit to process.

Answer This Question

We are having trouble properly securing the mounting post to the base. What is the correct way to fasten the post to the base? We tried screwing the bolt provided through the hole in the post (the hole that does not have a matching hole on the other side. The bolt does not touch the post on the back side, resulting in a rather flimsy setup. Thanks for your help.
