This ceiling leak diverter is made of 13 oz Heavy Duty Flame Retardant Vinyl Laminated Polyester (Translucent or Black). These heavy drain tarps protect personnel and equipment from overhead leaks, such as roof and ceiling leaks. The special design of the roof leak diverter catches and drains water safely away from the leak area. Heavy-duty metal D-rings are sewn into each corner of the drain tarp to facilitate hanging. Drain tarps of sizes larger than 10' x 10' have heavy duty metal D-rings on the center of each side. The roof leak diverter's drain spout connects to a standard 3/4" garden hose that serves as the drain tarp downspout.
