I'm using quick release on a GP Patty Wagstaff 80" w DA-50R

Made them myself, but would not make them again.

Hobby Lobby has several variants of latch pins ... reasonably priced.
personally I like their metal versions that only require a hole drilled in a mounting block for installation.

Have not had a minutes trouble with my home made ... makes removing the canopy a lot less aggravating. ( I'm lazy)
