KEY 
Our product pages detail the type of wiper mounting arrangement for each ball nut model. Brush wipers may require customer supplied retention primarily on the V-thread end of the ball nut (on models that do not have internal wipers and snap rings). A stamped flange retainer is available for many models that do not have internal snap rings for wiper retention (see data pages for available sizes).
