ABSTRACT:
A fitting arrangement and method of securing a fitting arrangement to a surface is provided. A plurality of adjacent fittings is coupled to and extends from a mounting surface of a structure in a well bore. Each fitting has an engagement surface that is configured to engage with an installation tool for coupling the fitting to the structure. The engagement surfaces of the adjacent fittings in the plurality are offset from each other to thereby define a clearance for the installation tool.
