Abstract
Disclosed is a tubular tension bar adapted for insertion in the vertically aligned terminal links of a conventional chain link fence during installation of the fence. The bar is of oblong, tubular cross-sectional configuration, formed of galvanized steel, sealed at each end, and characterized by its improved strength and shaped to provide a curvature about its major cross-sectional axis to fit closely in the bight of the vertically aligned, U-shaped openings formed by the terminal links of the fence fabric.
Claims3
An elongated tension bar for insertion in the bight of aligned, generally U-shaped portions of the terminal links of a chain-link fence, said bar being tubular and oblong in cross-sectional configuration and having a curvature about its major cross-sectional axis which substantially matches the curvature at said bight of the terminal links of the fence to provide the maximum distribution of compressive stress along said major axis, said bar being sealed at each end to prevent moisture access to its interior and having its terminal corners rounded to facilitate insertion in said aligned terminal link openings.
A tension bar as claimed in claim 3 in which said oblong tubular bar has a cross-sectional width of 0.7 inches and a cross-sectional thickness of 0.28 inches.
