MX8000CRAdjustable Angle holders MX8000CR (1-5/8″ 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″.Recommended poles for MX8000CRMX8719CR – 19 ft MX Step- Tube StyleMX8716CX – 16 ft MX Step- Tube Style – Single SpreaderMX8719CX – 19 ft MX Step- Tube Style – Single SpreaderMX8720CX – 20 ft MX Step- Tube Style – Double SpreaderMX8722CX – 22 ft MX Step- Tube Style – Single Spreader or Double Spreader Specifications:Construction: Anodized AluminumDiameter (Inches): 1-5/8″Finish: SilverMounting Style: SurfaceProduct Class: Mounting BracketsBox Dimensions: 6″H x 11″W x 22″L WT: 6.55 lbsUPC: 096811800120
