A pole assembly includes an elongated tubular member having an outer periphery with a pair of grooves therein, each groove defining a concave sidewall portion and a flat sidewall portion, a cam member comprising a plate-shaped portion and a pair of arms extending from a surface of the plate-shaped portion, the cam member configured to, while the major surface is adjacent a portion of the outer periphery, be rotated to cause each arm of the pair of arms to engage a respective groove of the pair of grooves, and a mount portion comprising a body defining a cavity having a pair of elongated sidewalls configured to engage respective outer surfaces of the pair of arms while the mount portion covers the cam member and the cam member is at least partially within the cavity to prevent the pair of arms from disengaging from the pair of grooves.

Pole assembly with dovetail cam structure for accessory mounting

A lighting pole is disclosed, which includes a hollow tube, and at least two nonintersecting walls extending over an axial length of the hollow tube to divide an interior of the hollow tube into at least three isolated chambers. At least one of the three isolated chambers defines a gap separating at least two of the isolated chambers.

Lighting pole with isolated axial chambers

A rope arresting apparatus for use with a rope having a first end and a weighted second end is disclosed. The rope arresting apparatus includes a cam portion for exerting frictional force on the rope and a pinching portion. The cam portion has a resting position and a pinching position. At the resting position, the cam portion is in frictional contact with the rope when the tension on the weighted second end of the rope is less than or equal to tension on the first end of the rope. A pinching point is formed when the cam portion at the pinching position engages the rope against the pinching portion.
