The 1SKB-R3224 Rotomolded GigDolly from SKB is rotomolded polypropylene caster board with 5.0" locking caster wheels. It is a wheeled platform that mounts to an SKB19-REX6 Expander or the SKB19-R1400 GigSafe.

Rotational molding is a 3-stage heating process that results in evenness all around the edges of the case. The polyethylene material is inserted into a mold, and then gradually rotated until the material sticks to the edges of the mold in an even pattern. Once cooled, this plastic material forms a strong bond that minimizes sagging and potential collapse. This case is manufactured to such high standards that it comes with a lifetime warranty against manufacturer's defects.
