In tight equipment shelter installations every square foot can count.  But tight spaces can also mean increased ventilation needs.  To increase ventilation and to free up valuable wall space, Openchannelflow offers factory integrated door vents for our line of Fiberglass Equipment Shelters. 

These vents, made from durable T-304 stainless steel and specially designed for demanding outdoor installations, provide thru-door ventilation in a variety of sizes:  from 12-inches x 12-inches to 24-inches x 24-inches. 

When used in pairs on double door assemblies, door louvers can significantly increase ventilation inside a shelter.

The vents are vision proof and have a interal insect screen.  On larger size vents, the fixed louvers also mean that prying fingers can't remove the louver to gain access to the interior of the shelter!
