4. Rod (2x)
The rod fixes the two holders together. Move one of the holders along the rod to keep the core
sample in place. It is possible to connect two or three rods together if the core sample is too long
for one rod. To affix the rod, insert and screw. To remove the rod from the holder, unscrew the
rod. If it becomes hard to unscrew the rod, use a 5/8'' wrench or the Allen key provided with the
Core Holder.
