Steel Single Deflection Supply Grille with 1/2" Blade Spacing (Heavy Duty)
Gymnasium applications require grilles that resist accidental abuse from gymnasium equipment, including basketballs and dodge balls impacting the surface of the grilles. Krueger offers the heavy duty 480 single or 4880 double deflection gym supply grille series for this type of application; the 14 gage blades can stand up to the accidental collision of most gymnasium equipment.
