The drylin® Q square guides ensure linear movement secured against rotation and are ideally suited for unsupported use. Thanks to the hollow profile, it is possible for cable feed-through. The user can choose between three installation sizes or three profile sizes and benefit from the five longitudinal grooves on the carriage for flexible connection of components. A manual clamp is also available as an option for the square guides. drylin® Q carriages can also be used on commercially available mechanical profiles of the same size.
