This rail connector is a wide, sturdy piece for quickly connecting rails in the Bosch belt system. The system works with the Bosch chainsaw. The FSNVEL is a top-installed and self-aligning connector that ensures precise work, even with multiple rails. The rails (sold separately) are exactly straight and manufactured to exact tolerances. The tracking system allows precise end-to-end cuts and plunge cuts, and it is precise and easy to work with. The saw together with the rails can make an easily transportable alternative to a table saw to a construction site. The cuts are in table saw quality and almost no splinters.
