CineSkates are a set of three wheels that quickly attach to a tripod and enable filmmakers to capture fluid, moving video footage without lugging heavy gear. CineSkates with the GorillaPod Focus can support cameras up to 5 lb (2.3 kg). SkatePlate attaches to increase the weight capacity to 11 lb (5 kg).
SkatePlate is a dolly frame for use with products equipped with Cinetics Quick Connect, like CineSkates and CineSquid. It has a retractable quick-set-up design that can support the heaviest cameras (for rigs up to 11 lb (5 kg). It includes easy-to-read illustrations found on the face of the SkatePlate for perfect alignment every time. The SkatePlate has a 1/4”-20 thread attachment.
