The Black Stallion AP3015 SmashPad FR Welding Mat helps to alleviate aches and pains associated with kneeling, sitting, leaning, and more during long welding runs. The foam cushioning provides supportive comfort while the inherently flame-resistant fiberglass outer shell resists sparks. Red 30 oz. silicone-coated fiberglass top surface is twice as thick for extra protection against sparks and spatter, with greater tear and abrasion resistance. Use the SmashPad for propping and bracing, reducing hand and arm fatigue or use for padding arm and elbow support and to lean against hot surfaces. Convenient carry handles and FR hook-and-loop closures keep the 16" wide x 19" long (16" x 9.5" when folded) Smashpad easy to transport. Easy to clean; Simply wipe off dirt and grime and dry. You can also connect two or more to extend padded surface.
