The Springfield taper-lock-flush mount base is constructed of die-cast aluminum. The 9" surface-mount
base does not require a large hole in the deck. Fits Hi-Lo Taper-Lock, Nonadjustable, Adjustable and
Power Pedestals.
Exchanged for Swivl-Eze Wedge Base after determining that installation was very difficult with the other base. Size not easy to determine on website but unit is 9" in Diameter. Mounting screws not supplied and size not available except from Mfg. and/or packaging when received and then not clear. Installation was easy and power pedestal works great.
The quality (thinner material) and construction of this item is not as good as compared to this same item that was made by Springfield and sold by Cabela's a few years ago. My Springfield pedestal ram mount did not fit and would not lock into the pedestal base. This was fixed by grinding some of the material out of the base but still not a good fit, the seat is wobbly. Check fit in a Cabela's store, I may just have got one missed by Springfield quality control.
