This is a replacement Ball End Base for Trimline awnings.
Similar to and same function as the now obsolete Dometic Ball End Bases for Trimline Awnings part# 3309924.003.
Seems to be durable enough in ABS but UV stabilized Nylon would be the best material to use.
Version 2 added. After testing last weekend I broke a few so I made some minor dimensional changes that puts less stress when inserting the ball end.
