Abstract: A conduit uncoiler assembly provides a mast carried by a base. The mast includes a central post carrying a plurality of radially extending support arms that support the bottom or base of the coiled conduit. Each support arm carries a radially extending retaining arm for supporting the inner diameter of the coil. The mast also carries at least one guide bar that continuously and automatically supports the top surface of the coil as the conduit is unwound. The system provides and maintains support to the bottom, top, and inner circumference of the coil as the conduit is unwound.
