The nylon retainer which holds up the non-motorized end of a Brustor awning is a weak point in the design. Worse, the company has no support network. I fashioned epoxy putty around the failed piece and later shaped the dried compound, drilled the safety pin hole. The fix is twice or three times the strength of the original part. Not a big problem with short awning assemblies, this part is simply too lightweight to handle the stresses of larger, ie longer, awnings. Monthly inspection can be made by peeking under the clamshell cover -- you need to check its security anyway -- to ensure operating safety.
