For your consideration is a pair of 90 degree rotating retracts that are made by Rhom Air. They have the 3/16" heavy duty struts. They are rated up to 14lbs. The kit includes everything needed to due a proper install.
These retract are dang near built proof with the exception of one weak link. That weak link is the stock air valve itself do to the piston has no stops. I have included a new air valve that has stops that takes care of this problem. I have personally updated my Rhom Air retracts in my old school pattern planes with this valve. Make a long story short I have not had one single failure in 5 years. (Knock on wood)\
I have 2 sets of these. Price is for one with free shipping in the US
