MX7000CRAdjustable Angle holders MX7000CR (1-1/2" ID) are our strongest and most versatile holders. The three point mounting distributes the stress and provides side support. This heavy duty unit allows you to set your outrigger angle for maximum efficiency. The angle is set by positioning the clamp on the main tube during installation. The main tube of this unit is designed to accept the outrigger in either end so the holder can be mounted above or below any flat surface. A fast pin can be substituted for the bolt connecting the clamp to the wing for bridge laydown capability. Approximate area required for mounting is 14-1/2" x 18".Recomended poles for MX7000CRAO8716CR - 16 ft Center Rigger (Mk II)AO8718CR - 18 ft Center Rigger (Mk II)MX8712CR - 12 ft MX Step- Tube StyleMX8715CR - 15 ft MX Step- Tube StyleMX8718CR - 18 ft MX Step- Tube StyleMX8716CX - 16 ft MX Step- Tube Style - Single SpreaderMX8720CX - 20 ft MX Step- Tube Style - Double Spreader
