The Mega-Jaw™ Carry Clamp has been designed for easier and safer carrying of countertops. The lightweight clamp (only 2.6 pounds) opens wide enough to accommodate tops up to 2.6" (66mm) thick! The clamp features high-strength aluminum arms, and non-marking, tear resistant rubber gripping pads. To distribute the weight of very heavy countertops, two installers per clamp can be used on each side of the top (four people total). The tension in the clamp is adjustable to allow the clamp to “hold on” to the top when not in use (won’t fall off). Each pair of clamps has a rated capacity of 500 pounds, and the more weight lifted, the tighter the clamps grip. All Omni Cubed products are engineered, manufactured, and assembled in the USA and are covered by a one-year manufacturer’s limited warranty.
