Abstract
Abstract An improved wall stud for use in framing a wall unit. Two separate sheet-like sections are roll formed with preselected folds and stitched together at a common double strength web. The composite stud includes an open surface channel for accepting a wall standard and bracket support structure as a unit so that installation costs are minimized.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
122 words
A roll formed stud for use in framing a wall unit comprising, in combination: a. a pair of unitary stud portions, each of said portions being a mirror image of the other and arranged back-to-back to form a common web; b. each of said portions including at least one inner flange and orthogonal interior edge defining a shoulder for forming a surface channel, at least one angularly folded section adjacent said common web, an inwardly projecting folded section adjacent said angularly folded section and said inner flange for forming a rear channel; and c. an acute angle is defined by the junction of said inner flange and said inwardly projecting folded section whereby a pincer is formed for retaining a bracket support.
Claim 2
