Polylok, Inc. is proud to offer our 12", 20" & 24" Safety Screens. These bright yellow, heavy-duty ABS screens act as a secondary layer of protection if the riser cover is unknowingly damaged, removed, or not put back on. The Riser Safety Screen fits in the upper most riser stack of our Polylok 12"x6", 20"x6", 20"x12" and 24"x6" risers and prevents entry into the tank. The Riser Safety Screen has been tested to 250 lbs. per sq. ft. and comes with a built in handle. For a better nights sleep, make this a part of your riser installation each and every time!
