18×3″ rectangle of 3/8″ thick waterjet cut AR500, for the most durable protector possible from edge to edge. Cutting via laser or plasma leaves a soft edge on the metal because of the extreme heat involved. One hole for mounting on our Enhanced T-Post Mount. Orders of up to 70lbs ship with a single flat rate price. ALWAYS keep in mind impact velocity and energy prevent target damage. Keep your impact energy around 2500 ft-lbs for 3/8″ thick AR500, and 2750fps or under to prevent pitting of the protector. We use only mill-certified AR500 for our protectors!
