Then pop the new shaft and roller into the door’s plastic base with a small rubber mallet … PRESTO! Doors re-hung and working perfectly now. (apologies to the manufacturer, but this was my “real world” experience). **Q: When I bought this house the bifolds were in and the roller guide missing. How do I determine what size roller guide to buy?** A: match the gap size of the track to the diameter of the wheel **Q: This is too big for my track. Is there one available just like this but smaller?** A: There are different sizes available. **Q: Is this a prop 65 product?** A: This item does not need a Prop 65 label. ## Frequently Bought Together - Prime-Line N 6703 7/8 In.
