The grooves 5 provided in the facing edges of the respective holder elements are spaced apart on centers. In one practical embodiment, Figure 4, the rods 3 are round and have a diameter x of. The side edges of each channel member 1, 2 are provided with grooves 5 for accommodating the rods 3. It is, therefore, an object of the present invention to provide a contour gauge of the type incorporating a plurality of rods arranged in side by side relationship in a holder or frame means and in which means are provided to adequately establish the requisite frictional restraint functions and which means are relatively nonwearing and functionally not affected by contaminating atem attraction to rods of steel or other magnetically suscep tible composition, to such degree as to provide a strong gripping action in drawing each rod to its prescribed stopping point, and a relatively Weak resistance to continued movement of the holder or frame means thereafter, so that the gauge is both accurate and easy to operate, permanently consistent, not susceptible to wear or other conditions which would deleteriously affect the functioning of frictional restraint materials generally and is of relatively light construction, because magnetic restraint does not require applied pressure to be effective, and structural provisions to withstand stresses produced by applied pressure are unnecessary.
