Manufactured and marketed by Tenneco Inc., the Mega-Clamp helps maintain proper emissions performance and offers protection against increased noise from leaks in exhaust system connections. Available in T304 stainless steel and aluminized steel, each Mega-Clamp features extra-thick steel bands and reinforced grade 8 bolts for added strength and durability. Unlike other clamps, which are often tightened with two hands and two wrenches, tightening the Mega-Clamp requires just one hand and one wrench, saving valuable time and effort in the garage or on the road.
