What is a Heim joint and why is it such an important feature?
The Heim joint is another name for a rod end bearing design. These have been used in automotive, marine and aircraft applications for many years and are not new, but are very effective for its use. The purpose of the joint is to ensure only axial (push and pull) forces are transferred and not twisting or torquing forces. The reason this is an important feature is that it prevents the gel coat cracking that has been reported with towers that used welded on fixed mounts. With fixed mounts when the tower flexes (which is normal) it “torques” or twists the mount which is bad for the gel coat. This is also what allows the Monster Tower to lay down so easily and quickly making storage a snap.
