The KV Venting Collection allows for fresh air circulation, featuring traditional styling. The doorlites are user-friendly and are virtually maintenance-free. The elevation series is standard in all 2236, 2248, 2064 and 2264 vents. The elevation vent is a unique venting unit with a weight balancing system. This ergonomic doorglass opens and closes easily as a result of this balancing system, which allows for better control and safer operation.
