Vertical slide provides camera access for photography
Enhances all helicopter operations.

They are made with extra stiffeners to prolong the life of the window and have a unique locking mechanism to secure the slide in place.
Lightweight construction has negligible weight change
Additional stiffeners reinforce window and eliminate vibration
Excellent for law enforcement observation and news gathering
