Need Stanley bi fold door parts




Hello,
Thanks for writing in! Your bottom track can likely be replaced with the 21-450 24" Low Profile Track Assembly. This track comes with (1) 21-175 Pivot Bracket, which is the one we recommend using to replace the one you have pictured since it is no longer available. It also comes with (1) 21-174 Roll Guide and (1) 21-286 Snugger.
The part you are referring to as the peg is the bottom door pivot. The one typically used with the corner block you have is the 23-113 Bi-Fold Bottom Door Pivot. If you have any other doors that do still have the parts in tact, it might be a good idea to compare them.
The pivot used at the top of the door is the 23-112 Spring Loaded Top Pivot.
