Flush Mount Rod Holder – 15 Degree ; 9 Depth – Stainless Steel – Cast Gimbal – White Vinyl Liner. These larger 70C series models feature a beautifully rounded cast bottom end with a 1/2 tapered pipe threaded drain. Use them when the bottom of the rod holder must have a decorative appearance or add a drain tube and use it when there is dry storage space under the rod holder. This rod holder features a super tough cast stainless steel gimbal bar designed to hold up to the punishment of downriggers or heavy tackle. A white vinyl liner protects rods and is keyed to the gimbal, so the liner stays in place. 1/2 pipe-threaded drain hole. Cap (L x W): 4-1/2 x 3-5/8 inches.
