L150 series (3-3/4" Outside Diameter) flexible L-jaw coupling spider insert.
Urethane spiders are harder and longer lasting in high torque applications than comparable rubber spiders.
Urethane is rated for 1.5 times more torque than NBR / Buna-N / Nitrile rubber inserts and is more chemical and oil resistant.
Interchangeable with Lovejoy, Martin, Browning, TB Woods, and other L-jaw couplers.

I ordered this to try as an alternative to Hytrel spiders, which seem to get worn quickly. Perhaps due to the increased flexibility, but it seems to work very well with little sign of wear. I will definitely order again.
