This is for the HS400-450-500 Vector UTV that has the Front Vertical Frame Rails of 46 1/2″ (Center to Center) wide.
Early 400 Models had 47 1/2″ and this newer model Vector 400-450-500 Windshield is 1″ narrower.
This has 6 Quick Release Clamps. If you need more Air Flow remove the bottom 1/3 section or just the upper.
This is a Tight and Clear Polycarbonate not like the early model that was made from the cheaper Plexiglass.
