The tree rod holder mounts to the 7/8” diameter mast by means of two stainless steel cap screws and lock washers. Unlike some competitors, the rod holder can be adjusted vertically and radially. Staggering the rod holders vertically along the mast allows for fast and easy removal of the lower rod without interference of the rod positioned above! In the bottom of each tube a machined extension mates with the cross cut in the rod handle butt to keep the rod from swaying. Tubes color upgrades are available in Bright Gold, Blue and Black. *Recommended use is 2-4 rod holders per mast.
