Adjustable Rod Holders

   The ARH series adjustable rod holders are designed to be used with our PR series precision rods.  Used together, the ARH and PR series give the experimenter both fine vertical and coarse rotational adjustment of equipment mounted to the PR precision rods.
   Our ARH precision rod holder allows a full 0.5-inches of fine vertical translation.  The translation feature functions under load allowing fine adjustment without releasing the rod.  To eliminate wobble, our ARH precision rod holders are double-bored to provide a true three-point contact on the PR precision rods.
