A good cable lashing device to use for communications cables where moves, adds, and changes are frequent is the?

The use of a Hook and Loop fastener is ideal for communications cables where moves, adds, and changes are frequent because it offers a combination of flexibility and ease of use. Unlike some other fastening methods, Hook and Loop fasteners allow for quick and efficient adjustments without the need for cutting or damaging the cable. This means cables can be easily re-secured when modifications are necessary, making it convenient in environments where frequent changes are the norm.

Moreover, Hook and Loop fasteners provide a reliable hold without exerting excessive pressure on the cables, which helps to prevent damage. This aspect is particularly critical in communications situations where maintaining signal integrity is important.

On the other hand, a Twist Tie and Zip Tie are less flexible since they can require cutting to remove or adjust, and can potentially damage cables if over-tightened. Electrical Tape, while useful for securing cables, creates a more permanent bond and is not as easily adjustable, making it less suitable for situations that require frequent access and movement of cables. Thus, the flexibility and user-friendliness of Hook and Loop fasteners make them the best choice in this scenario.
