Item #'s ending in "L" are left-hand thread (examples = 255-HL or 200-BL). Right-hand thread items are for use on the right side of the boat and left-hand thread products are for use on the left side of the boat. Why do we offer the option of right or left-threads?

As rigs are pulled toward the rear of the boat (either casted or being trolled) You want to keep the pressure always tightening the threads. If a rod holder were to not be completely tightened during installation, the pressure could loosen right-hand threads if installed on the left side of the boat (if not tightened properly). Using left-thread on the left side of the boat means the rod holder is being tightened as it is pulled toward the rear of the boat.

Right-hand threads install and tighten clockwise, left-hand threads install and tighten counter clockwise. Using the correct right-hand and left-hand products are important for applications in which the rod holders will be removed from the mount frequently, which can lead to them accidentally not being tightened properly upon reinstallation.
