Abstract: A manifold spreader which includes a main body portion having at its first end portion a recess in which is rotatably disposed a first end of an arm member. The arm member has a manifold engaging member on a second end thereof. A plurality of bearings mounted on the side of the arm member allows the arm member to freely rotate relative to the main body portion. The second end portion of the main body portion houses a screw member having on its first end a manifold engaging member. The body portion has a surface recessed therein to allow a wrench to engage and turn the main body portion.In operation, the apparatus is placed intermediate a pair of manifold arm members such that the first and second end portions of the apparatus are making contact with the manifold arm members. The main body portion is rotated in a first direction, causing the screw member to move outwardly from the central body portion, thus causing the apparatus to expand and force apart the two manifold arm members.
