Rosen Third Axis Update KIT

This 3rd axis modified block replaces the standard block to give you an additional range of motion- it allows the visor to swing downward at an arc. It is also useful on float planes with the V brace to maneuver the lens around the tubes. Each kit contains a pair of blocks, STC, and allen keys to switch out your blocks. Install time about 20 min.

Dimensions: 1X5.5X8.5
