While rear load dumpsters are not as common as front load dumpsters, they are the preferred containers for use in cities, alleyways, and other areas where space is limited. These dumpsters are also great for areas where there are low hanging power lines or wires. Rear load dumpsters may not be supplied by every hauler but, when they can be obtained, they are available in 2-yard, 3-yard, and 4-yard sizes.
