The Sentinel Mirror Kit includes two mirrors and all mounting hardware for quick, easy installation. The mirrors are 2.75" in diameter and are mounted at an angle. They can be rotated to dial in the perfect rear view. The mirrors can be mounted in a fixed or folding configuration. Folding allows the mirrors to be folded in and out of the way of covers. In the fixed mode, the mirrors are compatible with the Sentinel Armor and Hand Wrap (both sold separately). Note: Handguards sold separately.
