Select top mounting clamps if you prefer to install modules after securing the footings and the rails. This sequence is especially well suited for flush mounting. Top mounting clamps do not use module mounting holes, thus allowing flexibility in rail placement.
Ordering Mid Clamps: For each row, take one less than the number of modules in the row and multiply that figure by 2. For example, a row of 4 modules requires 6 mid clamps: (4 - 1) x 2 = 6.
