Middle Atlantic Products Vent Blocker Kit for ERK - 28 Inches Deep

Vent blockers are used to prevent the recirculation of hot air between top-mount fans and nearby vent openings. Vent blockers should be placed over the enclosure s vents located on the upper front of the enclosure and upper sides. This will ensure that heated enclosure air will be forced out through the top-mounted exhaust fans instead of re-circulating, keeping equipment cool.
