Unlike traditional oil drums, plastic screw top drums don't have a defined top lip to grip onto, for this reason we use a band on the DTC02 unstead of a drum gripper. We supply this plastic barrel trolley with a set of rubber-lined fixed radius pads. The pads grip the drum and along with the ratchet securing system secure the barrel in place. The pads accommodate a wide range of barrel diameters and are useful when unusual plastic barrels need to be moved. If you are handling a drum which has a defined top lip then our signature Universal Drum Trolley can be used instead.
