Middle Atlantics VBK Series, Vent Blocker Kit

Vent blockers 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, upper sides, and upper rear door (depending on enclosure). 

• Kits include the properly sized blockers for the intended model
• Proper installation will help the cooling system operate as intended
