Which tool is used to protect a hose line being hoisted above a roofline?

A hose roller is specifically designed to protect a hose line when it is being hoisted above a roofline. Its primary function is to minimize abrasion and damage to the hose as it moves over the edge of the roof. The hose roller allows the hose to roll smoothly over the edge while maintaining its integrity, which is crucial during firefighting operations where the hose must remain fully functional and free of kinks or cuts.

This tool also provides a stable surface for the hose, reducing the risk of it getting hung up or snagged during the hoisting process. By using a hose roller, firefighters ensure that the hose can be deployed quickly and effectively when it reaches the roof, which is essential for maintaining water flow during firefighting efforts.

Other tools, such as ladder hooks, are used for securing ladders, hose clamps are utilized to stop the flow of water in hoses, and safety straps serve to secure equipment or to provide safety for personnel. While these tools each have important applications in firefighting, they do not serve the same protective function for a hose line being hoisted as the hose roller does.
