A spool assembly configured to support a roll of material. The spool assembly comprises a first and second flange coupled together via a first and second arbor member. The first arbor member is slidably coupled within a first at least one slot of the first flange and slidably coupled within a second at least one slot of the second flange. A biasing member is coupled to the first arbor member such that the first arbor member is biased radially inward toward a longitudinal axis of the spool assembly. Rotation of the first flange relative to the second flange causes the first arbor member to translate within the first at least one slot and the second at least one slot causing a change in the arbor diameter.

A portable tape dispenser is disclosed. The portable tape dispenser can comprise a spool and two sidewalls which overhang the spool to capture a roll of tape on the spool. In some examples, one of the sidewalls can have a clip for attaching the portable tape dispenser to a user's clothing. In some examples, the tape dispenser can have features such as a through hole disposed in one of the sidewalls or an extension piece to adjust the width of the spool.

A machine for distributing insulation material from a package of compressed insulation material is provided. The machine includes a chute having an inlet end and outlet end. The inlet end is configured to receive the package of compressed insulation material. The chute further has a removable hose hub configured for wrapping with a distribution hose. The removable hose hub is further configured for engagement with opposing flange assemblies such that rotation of the hose hub results in rotation of the flange assemblies. A lower unit is configured to receive the compressed insulation material exiting the outlet end of the chute. The lower unit includes a plurality of shredders and a discharge mechanism. The discharge mechanism is configured to discharge conditioned insulation material into an airstream.

A stackable spool cable manager assembly may include a plurality of like cable manager spools. The cable manager spools may include a locking mechanism such that the cable manager spools can be stacked and such that when locked together a cable support arm of each the cable manager spools is offset from the others. A magnet may also be provided, for example, for securing to a bottom one of a stack of cable manager spools such that they can be secured to a metal tray or the like.

A locking system for a spool comprising a barrel, a flange, and a sliding lock. The sliding lock has at least one rail that slidably engages with at least one barrel detent and at least one flange detent to prevent rotation of the flange on the barrel. The sliding lock comprises at least one arm with at least one catch. The at least one catch can be removably locked into at least one recess on the flange.
