Embodiments relate generally to connectors for use with harness and backplate systems in an SCBA. An SCBA may comprise a backplate for holding a cylinder of air and a harness with straps operable to attach to the backplate. Applicants have developed a backplate connector that provides a reliable quick connection and disconnection for straps attached to a backplate. The connector may fit into a slot on the backplate. In some embodiments, a plurality of connectors may be used to connect a plurality of straps to the backplate. Additionally, the connector may comprise a clip or other attachment operable to secure one or more hoses of the SCBA. This design may prevent the air hoses being hooked accidently, and the attachment of the hoses may help to secure the connector into the slot of the backplate, reducing the change of the connector disconnecting during normal usage.

Embodiments of the disclosure include earplug dispensers that may comprise a rotating cam assembly operable to dispense one or more earplug to a user when a knob is rotated by the user. In some embodiments, the cam assembly may comprise and upper cam layer and a lower cam layer attached via clips to the rotating knob. Upon rotation of the knob, the upper cam layer may cause the earplugs to fall through one or more cavities to the lower cam layer. The lower cam layer may comprise a pushing structure operable to move the earplugs, upon rotation of the knob, within the lower cam layer to fall down through an opening in the dispenser. In some embodiments, the earplugs may fall through an opening in the rotating knob.
