Bases are designed for removable stanchion tubes held in place by set screws. (The tubes are not welded to these bases.)
The extra large plates on these stanchion bases provides greater support for the higher angled stanchion.
• Tubing OD = 1"
• Choice of 11° or 19° stanchion angle for mounting on highly cambered decks
• Trapezoidal plate dimensions = inboard/long side 4", outboard/short side 3"; these sides are 5" apart
• Base tube height = 3-1/4"
