The Bowens Double Carriage with Brake is a component of (or replacement part for) the Hi-Glide Rail System. A double carriage runner connects to the overhead rail and allows for complete freedom of movement along the rail, as well as the lower runner. It offers a 360° rotation, which enables you to position a second rail with lights attached in any direction that you need them.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.
