SPECIFICATION ABSTRACT OF THE DISCLOSURE A foot grille comprises closely spaced, parallel tread rails of uniform, T-shaped cross section joined by crosswise key lock bars. The lock bars are tightly wedged in triangular cutouts in the web portions of the rails between upper and lower flanges of the rails. The heights of the lock bars are greater than the heights of the web portions of the rails, and the lock bars are notched to receive the lower flanges of the rails, thus to fix the lower ends of the rails. The top edges of the bars tightly engage laterally spaced-apart areas of the undersides of the top flanges of the rails to fix the upper parts of the rails.
