The Bowens 6-Wheel Single Carriage with Brake is a component of (or replacement part for) the Hi-Glide Rail System. A six-wheel single carriage connects to the overhead rail, and allows for movement along the rail. This carriage is used when applied weights are greater than the standard single carriage (BW-2604) is capable of bearing. This braked carriage will stay locked in position. At least one braking carriage per rail should be used to ensure that lights stay in their desired position.
