Patent ID: 8776477

Claim:
A method of aligning a panel, comprising: providing a longitudinally extended base shoe defining a longitudinally extended channel and having two side walls and a concave base surface on an opposite side of the base shoe from the channel, the base shoe having a first longitudinal length; providing a plurality of mounting pad inserts, each mounting pad insert having a second longitudinal length, the second longitudinal length less than the first longitudinal length, the mounting pad insert further having a bottom surface having a bottom surface profile corresponding to that of a mounting substrate surface and a convex top surface profile corresponding to the concave base surface of the base shoe, the mounting pad insert positioned between the base surface and the concave base surface with the convex top surface of the mounting pad positioned adjacent the concave base surface and the bottom surface positioned in the direction of the mounting substrate surface; and placing the base shoe on the mounting substrate; inserting the plurality of mounting pad inserts under the base shoe such that the top surface of the mounting pad is adjacent the base surface of the base shoe; and adjusting the angular displacement of the base shoe in relation to the top surface of the mounting pad.
