Featuring all necessary components in a compartmentalized carry case, the E-Image Portable Camera Dolly with Tracks is ready to go out of the box for use with virtually all professional tripods. It supports up to 110 lb, and the track can be set up at lengths from 3.3 to 16.4'. High-density foam pads go underneath the aluminum rails to allow for safe and smooth operation. Thanks to these pads, the rails can be set up even on surfaces that are slightly uneven. The dolly wheels are designed to roll smoothly along the rails. At the same time, the rails have a film coating that makes them more wear-resistant for long-lasting performance. The system can be set up nearly anywhere, and it breaks down easily and packs away in the case for convenient transport and storage.
