The Auto Dolly docking system design eliminates the need to lift heavy wringer buckets, because it securely locks delamo buckets into place at floor level. This back-saving feature is exclusive to delamo. This unique trolley dolly is also a docking station for all delamo wringer buckets. Designed with a large footprint and seven 3\x94 caster wheels for stability and a base platform for stick tools when used with the Dynamo utility can, also fits most waste receptacles. In addition, it features a foot pedal lock to engage and release the delamo wringer bucket. Maximum load weight: 250 lbs. Made in USA. 1 each
