scored my third used topper over the summer, first one for me with keys for the lock included. duck season opens this coming weekend so i put it on over this past weekend, and upon putting the lock in the handle, everything internally is corroded and seized. in doing some reading it sounds like these things don't usually last a year here in the salt belt, so i'm curious if there are any aftermarket locking T-handles available anywhere that don't have internals made of chinese pot metal?
