The drylin® Q square guides ensure a linear, torque-resistant movement and are ideally suited for the unsupported application. Thanks to the hollow profile, feed-through of cables is possible. The user can choose between three installation sizes or three profile sizes and benefits from the five longitudinal grooves on the carriage for flexible attachment of components. A manual clamp is available as an option for the square guides. The drylin® Q carriages can also be used on identically dimensioned, standard machine construction profiles.
