If you require maximum load capacity, the RocknRoller R14G Mega Ground Glider is the industrial strength, heavy-duty workhorse you need! Featuring thicker tubing, and capable of holding up to 700lbs, the R14G can expand to a massive 60 inch length, with a 15 inch wide frame bed that increases load stability with stacked cargo. In fact, the R14G can carry 20 percent more cubic ft worth of gear than an R8 or R10. Rugged, foam-filled no-flat 8x3-inch rear wheels and 6x3-inch front casters come standard. The R-Trac tires ride smoothly with excellent traction, similar to pneumatic tires, but without the hassle of upkeep or repair. The patented 8-in-1 cart can transform easily to adjust to various load sizes, allowing you to move large amounts of gear in no time at all. The textured powder coated steel is durable and also reduces slippage during transport.
