The original plate design was narrower but I have since made it deeper to accommodate a wider range of plotters.
Total Cost for the mount comes in at:
1 - Compass Marine Mounting Plate = $58.25
4 - 316 SS Clamp Collars = $128.00 ($68.00 if using 303/304SS)
1 - SG10 Pedestal Guard = $139.00 - $170.00 (prices vary by vendor)
TOTAL = HIGH RANGE $356.75
TOTAL = LOW RANGE $265.75
