A traditional caster design, the hot forged top plate and yoke base are held securely in alignment with a grade 5 kingbolt. The kingbolt is tightened to assure smooth swivel action before being pinned in place. The hot forged swivel sections and industrial width wheels are well suited for many in-plant applications. The added strength of the kingbolt provides extended caster service life in very demanding environments.
