The present invention relates to a method of forming a ceiling. The method comprises the steps of setting a tool for a desired length of crimp of a tee or main by adjusting a plate in a slot of the tool. Then the tee or main is cut to a desired length. An end of tee or main is inserted into a slot in the tool to a desired length. Then the crimping tee or main is rotated about 90 DEG with the tool without removing any length from the tee or main. The tool is separated from the tee or main. The present invention also relates to a tool to crimp a tee or main. The tool comprises a housing having an end, with a first slot disposed in the end. Additionally, the tool comprises a plate disposed in the first slot of the housing. The plate is adjustable in regard to position in the first slot so the tee or main can be inserted into the first slot a desired distance defined by where the plate is disposed in the first slot. In another embodiment of the invention, the tool has a pair of relatively rotatable elements each having a handle and a clamping portion so as to facilitate firm interengagement with the tee or main during crimping and ready release thereafter. An adjustable slot is provided in the tool so as to control the depth of crimping.
