2 lbs/ft U-Channel Post
- Item #:
- Y3432, Y3485, Y3486, Y3434, Y3435, Y3437, Y3438, Y3439

U-Channel posts for mounting parking and traffic signs are available in multiple sizes, ranging from 4 to 12 feet. Each post has standard hole diameters of 3/8 inch spaced out 1 inch apart on center.
These posts are available in galvanized or green enamel coated finishes. The galvanized finish provides the most resistance to rust and is the better option for those where durability is a concern. The green enamel coated finish, meanwhile, provides the more “natural” look, allowing the post to blend in with the environment.
Please note that 8 ft. posts are shipped via UPS and FedEx ground service while 10 ft. and 12 ft. posts will be shipped as freight due to their size. After you place your order, one of our customer service representatives will contact you with the correct shipping charges. Freight shipping requires a tractor trailer to deliver your post(s) as well as the rest of your order and is more costly than typical ground shipping. Typical freight charges can range from $150 to over $400 depending on the destination and size of the order.
Sign mounting hardware is sold separately.

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 | 1.12 lbs./ft. | 18″ - 24″ | 1-1/2″ Long |
6 ft. | Green Enamel & Galvanized | 2 lbs./ft. | 18″ - 24″ | 2-1/2″ Long |
8 ft. | Green Enamel & Galvanized | 2 lbs./ft. | 30″ - 36″ | 2-1/2″ Long |
10 ft. | Green Enamel & Galvanized | 2 lbs./ft. | 36″ - 42″ | 2-1/2″ Long |
12 ft. | Galvanized | 2 lbs./ft. | 36″ - 42″ | 2-1/2″ Long |
* Installation Depth Notes:
- 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″.
- 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.
- 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.
Installing Standard Hex-Head Bolts
Hardware required:
- Our Y4899 or Y3465 bolt sets.
Tools required:
- A ½″ socket and ratchet wrench, and ½″ combination wrench.
Installation instructions:
- 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.
- 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.
- Insert a washer on the other end of the bolt followed by the nut and tighten the nut down.
Optional:
- Add a pair of our ribbed sign saver plates that prevents the possibility of sign dimpling during bolt tightening.
Installing Tamperproof One-Way Bolt Set
Hardware required:
- Our Y4900TS or Y4901TS bolt sets.
Tools required:
- Our Y4965 screwdriver with for one-way bolts.
- ⅝″ socket and ratchet wrench
Installation instructions:
- 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.
- Using our Y4901TS or Y3551 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.
- Insert a washer on the other end of the bolt followed by the breakaway nut with the cone end facing the post.
- Tighten the nut down until it shears from the cone.
Optional:
- Add a pair of our ribbed sign saver plates that prevents the possibility of sign dimpling during bolt tightening.
