Depth Raider One-Hand adjustable Clamp-On Rod Holders are based on our Classic Rod Holder that features 5 adjustable positions from vertical to horizontal. Add these clamp-on rod holders to the pipe or tubing used in your hardtop or radar arch to create a rod tree on each side of the boat. Or add an additional rod holder to your existing rod tree. Be sure to specify which size you need. 1-1/2” pipe (1.9” OD) or 2” OD tubing. These rod holders feature our exclusive ULTRA-TEX textured finish to cut glare and provide just the right amount of sheen. CNC precision machined from marine grade aluminum in the USA by Depth Raider Marine Products.
