These seat rails have only pilot holes drilled in the rail base allowing
the installer to exactly match the aircraft floor rivet pattern. The
manufacturer discovered while installing and developing our replacement
seat rails that the seat rail attachment hole pattern was not consistant
from aircraft to aircraft. Even small inconsistancies in the hole
locations in the aircraft floor make installation of new seat rails very
difficult. For this reason, all these seat rails have only a few
smaller pilot attachment holes drilled at the factory. This allows the
installer to precisely locate the attachment holes to match the holes in
the aircraft floor. All special sized or machined attchment holes are
factory machined to finish dimensions. It is necessary to install all
required fasteners when seat rails are installed.
After studying countless worn and failed seat rails these rails were designed with 15% more metal in critical areas. The result is more crack resistant, durability, strength and longer life.
