Tendon Base - N Pin and Push Pin.
After recent quality inconsistency of the widely used black tendons, Aeron have worked with material suppliers to come up with a more superior and  stable material.
Up to now the industry standard has been a poured Urethane Material – we have now made a New Standard with an injectable Urathane that has proven itself for over 12 months of testing . The nature of this material means that tendons can only be injected in clear or opaque  for ultimate strength and durability.
• The Universal adapter quickly converts the N pin to fit the Dual pin system. This is also a stronger, more secure option to the STD push pin cup.
