FLUSH MOUNT. Stainless Steel Rod Holders. With 1/2 Threaded Drain. 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 when there is dry storage space under the rod holder. They feature 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 with the gimbal so the liner stays in place ANGLE:.15°LENGTH:.9"I.D.:.1-5/8".
