Commercial Side-Folding Security Grilles

When overhead clearance is limited or doorway openings follow a wide, curved footprint, Overhead Door Side-Folding Security Grilles deliver the ultimate security solution. At Timbers-Kovar, we supply and install these versatile side-sliding grilles to secure mall storefronts, airport terminals, bank counters, and hospital corridors.

Operating along a top-mounted ceiling track without requiring floor tracks or overhead coiling hoods, side-folding grilles stack neatly into compact side pockets when fully open.
