This base is a die-cast alloy fitting finished but not painted. You simply paint the base with an aluminium etch primer and then a final coat the colour of your choice. The base measures 230mm diameter and requires an 80mm hole to be bored into the floor of your cockpit or cabin. Six holes 8mm diameter and countersunk will fasten the unit. It is recommended that metal thread stainless steel screws only be used with DURALAC sealing compound.The heavy duty seat base has slotted holes to fix to almost any commercial seat available (fits 2 - 3.8"), including all of our seat range
