Gilpin 579 Windsor Floor Flange 1-1/4 in Square Tubing

Product Description

The GILPIN 579 is a floor post flange designed to anchor square-tube newel posts and columns to wood or concrete surfaces. It accepts 1-1/4 inch square tubing and provides a clean, stable base for surface mount applications. The flange serves as the critical connection point between the post and the floor structure, transferring load and resisting lateral movement. Installation is handled by finish carpenters, stair contractors, and general contractors working on railing and balustrade systems. At 0.45 pounds, the 579 is a lightweight but purpose-built component that keeps the finished assembly flush and secure at the base.

This flange is specifically used with Windsor newel posts, Newport columns, and Windsor columns in surface mount configurations. It is suited for both residential and light commercial applications where square-tube post systems are installed directly to wood subfloors, wood decking, or concrete slabs. The surface mount design eliminates the need for embedded anchors or pocket installations, simplifying the rough-in process on finished or retrofit surfaces.

Installation Notes

Installation is typically performed by finish carpenters or stair contractors using standard hand tools and appropriate fasteners for the substrate type. When mounting to concrete, use code-appropriate anchors rated for the load. Secure all fasteners before attaching the post to ensure the flange is fully seated and level. Always verify local building codes for railing and balustrade anchor requirements before finalizing the installation.
