U-Channel Post Installation

The following table details the recommended installation depth for U-Channel posts without the use of an anchor post. SafetySign.com recommends the use of an anchor post with every post installation to increase safety in the event of a vehicle collision with the post, and to help maximize the amount of available space on the post for mounting a sign.

  • Post Size Post Material Post Weight/Ft. Recommended Installation Depth* Bolt Size Requirements
    3 ft. Anchor Green Enamel & Galvanized 2 lbs./ft. 30″ - 32″ Use Breakaway Hardware to Connect to Sign Post
    4 ft. Green Enamel 2 lbs./ft. Up to 18″ 2-1/2″ Long

    6 ft. Green Enamel & Galvanized 2 lbs./ft. 18″ - 24″ 2-1/2″ Long

* 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 Sign Mounting

There are two types of hardware that can be used for mounting signs to a U-Channel post; a standard hex-head bolt set, or a tamperproof one-way bolt set.

Hardware required:

Tools required:

  • A ½″ socket and ratchet wrench, and ½″ combination wrench.

Installation instructions:

  1. Place the sign on the U-Channel post where it meets your height requirement and line up the mounting holes with the holes on the post.
  2. Using our Y3465 or Y3550 bolt sets, insert a washer over the 5/16″ bolts and then insert the bolts into the mounting holes of the sign and through the post.
  3. Insert a washer on the other end of the bolt followed by the breakaway nut with the cone end facing the post.
  4. Tighten the nut down until it shears from the cone.

Optional:

  • Sign Mounting Hardware

Installing Tamperproof One-Way Bolt Set

Hardware required:

  1. Our Y4900TS or Y4901TS bolt sets.

Tools required:
