The Model 420 provides a rotating connection for low power (600 V/50 A) and signal cables. Cable entry is by connectors or through integral junction boxes. It is intended for use in Catenary Anchor Leg Mooring (CALM) buoys and similar installations.

This model has no hollow bore, so it must be located at the top of a swivel stack. This also makes it the swivel of choice when a fiber optic rotary joint is required. If a hollow bore is required, use the Model 440.

The swivel is certified as a flameproof enclosure with flameproof connectors or increased safety junction boxes on the ship side (Ex de). It is certified for use with intrinsically safe circuits (Ex de[ib]). Ingress protection is IP66/IP68-20 m.
