Seat Mounting Jig (Seat Mounting Tool) by Righetti Ridolfi and IKP.
This jig is ideal for helping to mount kart racing seats in chassis of various size.
One bar (the upper bar pictured) adjusts rests against your frame rails so the bottom of the seat has a support point for height adjustment. The other bar rests against the axle to allow angle adjustment.
Jig is composed of two components:
Under-seat support bar
Axle to the rear-of-seat bar.
Each jig component is chrome plated for durability, and features an adjustable width slider with clamping screw for a range of use.
