8 Ft Square Sign Post With Pre-Drilled Holes

The package includes two 2″ wide by 4′ long square galvanized steel sign posts, plus a 10 cm connector and splice parts to secure the sign. The tube wall thickness is 0.08″, providing stability while remaining manageable for installation. Pre-drilled 7/16″ holes are spaced to fit standard tools, enabling straightforward assembly. The design emphasizes wind resistance and stability by offering a larger contact area compared to round poles, helping signs stay aligned in windy conditions. Each post is pre-drilled for quick height adjustments, with center holes spaced 2″ apart for precise sign placement. Tools required for installation include a screwdriver and pliers (not included).
Square Sign Post Anchor Base

Designed to fit 2″ x 2″ outside diameter square sign posts, this anchor base provides a surface-mount solution for durable installation. Made from low carbon steel with an electro-galvanized finish, it combines strength with corrosion resistance. The post pre-drilled hole diameter is 7/16″ and the hole spacing is 1″, enabling efficient alignment and secure anchoring of the post. This base is especially suitable for concrete or asphalt mounting where a stable, low-profile connection is required.
SmartSign Square Sign Post Kit

This kit features a 6-foot tall galvanized steel post measuring 1.5″ x 1.5″ with a base for concrete or asphalt mounting. The 14-gauge (.125″) steel construction offers durability and a long service life, making it a cost-effective option for municipal or campus signage. Installation involves multiple rivets on all four sides to allow several signs to be mounted. Holes are placed every inch on center to accommodate various sign sizes. Wedge anchors supplied for base mounting into concrete or asphalt require a 5/16″ drill bit and a 2″ drilling depth to install bolts. The post is rust-resistant due to hot-dip galvanization, ensuring longevity even in harsh weather conditions.
SmartSign U-Channel Sign Post

The U-Channel post is a medium-weight, 6′ tall post made of baked enamel steel. It comes in a pack of four and features pre-drilled holes: 3/8″ diameter located at the top 30 inches of the post. Holes are spaced at 1 inch on center, enabling straightforward alignment for mounting signs that are 12″ x 18″ or smaller. The medium-weight construction balances strength with ease of handling for installation on sidewalks or road medians. The post’s baked enamel finish provides a corrosion-resistant surface suitable for outdoor environments.
Sigo Signs Bracket For Square And Pipe Posts

The bracket accommodates standard signs with a 5 1/2” length and fits both 2 3/8″ pipe posts and 2″ square posts. Buyers can select brackets designed to hold flat or extruded street name signs, allowing compatibility with a range of sign types. This flexibility makes the bracket a practical accessory for projects requiring multiple post configurations or sign sizes.
Buying Guide
- Post material and finish: Galvanized steel offers durability and corrosion resistance, while baked enamel coatings add an extra layer of protection for U-channel posts.
- Hole configuration and spacing: Pre-drilled holes simplify alignment and installation. Verify hole size (commonly 7/16″ or 3/8″) and center-to-center spacing to match your sign hardware.
- Wind resistance and stability: Square posts increase contact area with signs, improving wind stability compared to round posts. Consider taller posts for higher traffic areas or heavier signs.
- Mounting method: Anchor bases are convenient for certain surfaces, while direct embedding or wedge anchors are better for permanent installations in concrete or asphalt.
- Sign compatibility: Check post dimensions (width, height, and weight) and bracket compatibility to ensure signs fit securely without excessive wobble.
- Installation requirements: Determine whether tools like screwdrivers, pliers, or power drills are needed. Some kits require specific drill bits (e.g., 5/16″ for wedges) and depth for secure mounting.
- Maintenance and longevity: Look for corrosion-resistant finishes and rustproof coatings to minimize maintenance costs over time.
