4 Inch Steel Square Pole Installation Kit with Base Cover | Bronze

Product Overview

This installation kit provides the anchor hardware, positioning plate, and covers required to install 4-inch bronze square steel poles at 15, 20, or 25 foot heights. The kit is designed for direct burial anchor bolt installation into a concrete foundation.

The kit includes four 19.69-inch threaded rod anchor bolts, eight M20x2.5 nuts, eight M20 washers, and a 9.8 x 9.8 inch positioning plate for setting the anchor pattern in wet concrete. A bronze base cover measuring 10.9 x 10.9 x 5 inches conceals the anchor bolt connections at grade level.

A 4 x 4 inch rain cover is included for applications where arm-mounted fixtures are used instead of tenon-mounted fixtures. The compatible poles ship with 2 3/8-inch tenons as standard, so the rain cover seals the tenon opening when arms are installed on the pole shaft.

Where This Product Fits Best

This kit supports installation of 4-inch square steel poles in parking lots, walkways, building perimeters, and other site lighting applications where a bronze finish is specified. The anchor bolt length and base plate dimensions are sized for standard concrete pier foundations.

The bronze base cover provides a finished appearance at grade and protects the anchor bolt connections from debris accumulation and moisture exposure. This kit is appropriate for new construction or pole replacement projects where the foundation will be poured to accept the included anchor hardware.

Performance and Functional Considerations

The four-bolt anchor pattern with M20 hardware provides the connection strength required for poles up to 25 feet in height. The 19.69-inch threaded rod length allows for concrete embedment depth while leaving sufficient thread exposure for leveling and securing the pole base plate.

The positioning plate holds the anchor bolts at the correct spacing and orientation during concrete placement. This ensures the bolt circle matches the base plate pattern on compatible poles without field adjustment after the concrete cures.

Installation and Long-Term Use

The positioning plate is set on the concrete form and the anchor bolts are suspended through it before the pour. After the concrete cures and the forms are stripped, the pole is set over the bolts and leveled using the nuts and washers. The base cover slides over the pole shaft and seats against the foundation to conceal the hardware.

For tenon-mount fixtures, the pole ships ready to accept luminaires directly. For arm-mount configurations, the rain cover installs over the tenon opening at the top of the pole to prevent water intrusion into the pole interior.

How This Fixture Is Commonly Used

This kit is typically staged at the job site before foundation work begins. The positioning plate is placed on the concrete form, and the anchor bolts are threaded into position and braced to remain plumb during the pour. Once cured, the pole is lifted onto the bolts and the leveling process begins.

The base cover installs after the pole is secured and any wire pulls are complete. It provides access protection and a clean finished appearance at grade level. The rain cover is installed at the top of the pole only when arm-mounted fixtures are used instead of tenon-mounted fixtures.

Safety, Certifications, and Warranty

This installation kit is covered by a 1-year warranty. The warranty applies to the anchor bolts, nuts, washers, positioning plate, base cover, and rain cover included in the kit.
