Each Rubber Panel weighs 37 lbs. & is 24″ Wide by 24″ Tall by 2″ THICK. The manufacturing process of combining high pressure and a weather resistant high tech polymer binder allows for an extremely dense & consistent Rubber Panel. Mounts to existing armor steel plate & significantly reduce any chance of bullet back splatter, ricochet & airborne lead. “Ricochet Testing” done by an Independent Testing Agency has confirmed that they will absorb all 9mm Luger 124 grain, FMJ rounds at an angle greater than 5 degrees and 5.56 x 45mm 62 grain, M855 ball rounds at an angle greater than 10 degrees.
