This is a set of three Premium series swivel track Dolly Trucks for the K-Pod tripod, from Kessler Crane . In comparison to the standard wheels, the premium wheels come with two long-lasting, precision-sealed bearings in each wheel. Made of Grade A precision-machined cast 95A polyurethane, these wheels are smooth and will not develop flat spots over time, something that's common with most injection molded wheels.
These trucks work on curved or straight track ranging from 1" to 4" in diameter. If you'll be using these trucks with flexible track, Kessler highly recommends their 3" or 7" Idler Arm Upgrade for the best possible performance. If you'll be using them with standard 24" wide doorway dolly track, a 7" Idler Arm will be required. All Idler Arms are sold separately.
