The CRL Split Case Dolly is designed as two separate carrying frames, each with a 12" diameter x 3" wide (305 x 76 mm) steel ball bearing wheel. The upper portion of the frame is made from 2" (51 mm) steel angle. It stands 47" tall and is 34" in length (1.19 m x 864 mm). The lower angle provides a 3" (76 mm) lip to support each side of the bottom edge of the glass crate. Once the glass crate is lifted, move the two halves of the dolly to the sides of the crate, close to the middle, and lower the crate onto the lower supporting angle. Once loaded into the Split Case Dolly even glass crates weighing as much as 4,400 lbs. (1996 kg) can be moved about your shop with relative ease.
