Abstract
An exercise rowing machine has a tubular center rail of generally rectangular shape secured to underlying frame members by carriage bolts that have their head slide-mounted in a T-slot formed on the underside of the rail. The rail is formed with side channel tracks for the rollers of the seat carriage. End plates on the rail serve as travel stops for the seat carriage and are mounted by screws passing into longitudinal grooves formed on the inside of the rail. A timer is housed in the rail.
