A device for forming a planar mounting surface in a chosen reference plane forward of one or more of structural members having a front face at least partially displaced rearwardly of said reference plane has a member (30) of extended length including a pair of legs (36, 38) supported by a perpendicular base portion (32). The legs define a pair of parallel faces spaced a distance corresponding to the width of the structural member (16') upon which the member is to be mounted. The base has an outward-lying flat planar face. The member is aligned on the structural member such that the outward-lying face is oriented and maintained along the reference plane, and the member is nailed or otherwise affixed to the structural member.
