What components should be included in commercially available wrap strips?

The correct choice incorporates essential elements typically found in commercially available wrap strips, particularly in the context of electrical or data cabling installations.

Wrap strips are used to protect and organize wiring in various environments. Including components like sleeve material ensures that the cables are insulated and protected from physical damage, while wall flanges provide a secure and tidy outlet for cabling through walls. Couplings allow for the joining of different segments of cable or conduits, ensuring that the intricacies of the installation are managed safely and effectively. Rated bushings are crucial as they protect the edges of openings where cables pass through, preventing wear and damage. Documentation labels help with maintenance and identification of cables, ensuring that technicians can easily locate and manage wiring in the future. Furthermore, incorporating firestop material is critical for maintaining fire safety and adhering to building codes, as it helps to prevent the spread of fire through openings and between compartments in structures.

While the other options contain components that are relevant in their own contexts, they do not address the specific requirements and components necessary for wrap strips in the same comprehensive manner. For instance, mentions of sockets, power supplies, or technical manuals do not directly apply to wrap strips and their function in cable management and protection.
