Both size dumpster rentals are open top, and have a door on the back of the dumpster that is the entire width of the dumpster rental (8 feet). If you open the door to load the dumpster, make certain that you have closed and secured the door before calling for the dumpster to be removed. Do not place any material above the top rails of the dumpster, and do not have any material protruding from the dumpster rental . When the dumpster rental is picked up it will be tarped for transport and must be road safe. If the dumpster rental is overloaded the excess material may be removed by the driver or the dumpster may be left until the customer removes excess debris.
