Elements (aka Spiders, Grommets)

Flexible elements, also known as spiders or grommets, help in the coupling of two drive shafts and determine the coupling's torque rating. Reuland offers two durometers, 34 and 50. The 34 durometer (series L9) is excellent for use in light to medium duty applications, while the 50 durometer (series H5) are for medium to heavy duty applications.
