* Installation Depth Notes:

1. The depth numbers we are providing are general guidelines and do not take into account the different types of soil in your specific location. When possible, it is ideal to install u-channel posts to a depth of 30" - 36".

2. A breakaway system should be used when installing posts on public roadways and on private roads open to public travel such as those running through a non-gated corporate complex or shopping center. Our breakaway anchor post should be installed approximately 32" into the ground.

3. Be aware of frost lines as they vary by region of the country.

U-Channel Post Description

  • U-Channel sign posts are built for strength and reliability - and made with the finest high-carbon built steel.
  • They are engineered with a patented ribbed back design - adding strength to crucial load-bearing points. This added strength enables our posts to handle more signage than any other U-Channel posts.
  • Galvanized Steel or Green Enamel Coated Steel.
  • Mounting holes: 3/8" on 1" centers beginning from the top of the post, running the entire length of the post.
  • Posts 10-ft & 12-ft cannot be shipped UPS. Customer Service will give you a call with correct freight charges after your order has been placed.
