737 J rails for IPECO J rail seats. Virtually impossible to find, and extremely expensive if you luck out and find a set. This is 1/2 of a full set; complete for the F/O side. Using these as a pattern you can have the left side duplicated. In the end you will save a LOT of money, time and effort. Made from composite material, stronger than typical plastic. However; while fine for home sim use, these will not hold up under daily abuse in a professional sim. We have sold 30 sets which have been used successfully in home sim installations.
