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.***

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.

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.
