The MultiCart RocknRoller R12RT 8-in-1 All-Terrain Equipment Cart is adjustable from 34 to 52" in length in eight different configurations and supports up to 500 lb loads. It's suitable for audio and film/video/photo gear, facility maintenance, trade shows, and any other use requiring a heavy payload and adjustability.

The RocknRoller features a 13.5" wide frame bed and has foldable sides measuring 32". The sides can be raised on one or both ends to better secure your equipment. What makes this an all-terrain cart are the patented R-Trac wheels. There are rugged, foam-filled, no-flat 10" wheels in the rear and 8" no-flat swivel casters with a brake in front. These are made for just about any terrain, such as rough and tricky surfaces like gravel and grass. The R-Trac tires provide a smooth ride with superior traction. The cart frame is made of powder-coated, telescoping steel tubes. When it comes time for storage, the cart folds up compact and nearly flat to fit in closets and similar spaces. The R12RT model has a black and yellow design with a bit of silver, in contrast to its sister cart, the R12STEALTH, sold separately, which is identical but comes in black and silver only. Various optional accessories are available for the cart from MultiCart, such as an extendable shelf, a solid deck, a cargo extension rack, and a laptop shelf.
