Ok, were not 100% sure on what we should measure so weve taken several measurements.
Measuring from one stud hole to the adjacent stud hole for each pattern we get:
3" For pattern 1, 3 1/4" For pattern 2
Measuring between alternating studs (IE start on stud one, end on stud 3) measuring center to center we get:
4 3/4" For pattern 1, 5 1/4" For pattern 2
Measuring between alternating studs, from the center of one to the outer edge of the other we get 5 1/8" or 5 5/8".
Hope this is ok?
Thanks
Dave
