An apparatus and method for dispensing wire or cable from a reel assembly. In one embodiment, the apparatus comprises an inner flange assembly and an outer flange assembly. The inner flange assembly is capable of freely rotating relative to the outer flange assembly for dispensing wire from any surface. In another embodiment, the apparatus includes an inner flange assembly, an outer flange assembly, and an external bay. The inner flange assembly is capable of freely rotating relative to the outer flange assembly and the external bay. The external bay is capable of freely rotation relative to the outer flange assembly and the inner flange assembly. In another embodiment, wire is dispensed from a reel assembly comprising an inner flange assembly and an outer flange assembly. In yet another embodiment, wire is dispensed from a reel assembly comprising an inner flange assembly, an outer flange assembly, and an external bay.

A hose reel assembly can include a hose reel rotatable about a reel axis, and a first portion of linear material having a first proximal end portion and a first distal end portion, the first distal end portion configured to dispense a fluid. The hose reel assembly can include a second portion of linear material having a second proximal end portion connected to the hose reel and a second distal end portion. A connector can removably attach the second distal end portion of the second portion of linear material with the first proximal end portion of the first portion of linear material. A strain relief member can be configured to control an amount by which the second portion of linear material unspools from the hose reel.

A fall arrest device includes a bracket, a rotating member rotatably mounted to the bracket, a safety belt wound around the rotating member, a brake wheel connected to the rotating member, a brake block pivotally connected to the brake wheel, and a restoring spring fitting around the second segment and having one end thereof terminating in a ring that has an inner diameter smaller than an outer diameter of the first segment. Another end of the restoring spring is connected to the brake block. The brake wheel has a fixed rod having a first segment and a second segment. An outer diameter of the first segment is greater than an outer diameter of the second segment. The restoring spring urges the brake block to be located in a restoring position. Thus, the restoring spring could be prevented from falling out of the fixing rod.

A fall protection device and its safety belt base. The fall protection device adapted to be connected to a safety belt includes a frame, a shaft, and a safety belt base, wherein the frame has a receiving place. The shaft is disposed on the frame. The safety belt base fits around the shaft and is located in the receiving place. The safety belt base includes a first portion and a second portion. The first portion has a ring, and the second portion has a sleeve and a reinforcement portion connected to the sleeve. The sleeve is surrounded by the ring and is adapted to be connected to the safety belt. The reinforcement portion is embedded in the ring. With the reinforcement portion, the structural strength of the safety belt base could be reinforced, and the first portion and the second portion could be prevented from disengaging from each other.

A retractable leash device (e.g., for pets, children, or the like) having a length control system for limiting the extendable length of a main line is provided. The device includes a cover plate mounted on a wind-up spool and having at least one ridged channel that interacts with a length control switch during line extension to control the extendable length of the main line while simultaneously maintaining the retractability of the main line.

A stop ball for a tube for fluid or energy is provided. The stop ball comprises a singular hollow body. The hollow body comprises and is integral with a first opening for the tube and an attachment means for attaching the stop ball to the tube, the attachment means comprising a second opening for the tube. A method for attaching a stop ball according to any one of the preceding embodiments to a tube for fluid or energy is provided. The method comprising inserting the tube through all three openings; pulling the attachment means at least partly out of the hollow body; and clamping the attachment means onto the tube.
