What characteristic allows a pliable Type ENT raceway to be manipulated easily?

A pliable Type ENT (Electrical Nonmetallic Tubing) raceway is designed for ease of installation and flexibility, allowing it to be manipulated without the need for specialized tools or equipment. The ability to bend by hand provides significant advantages in various installation scenarios, such as navigating around obstacles or fitting into irregular spaces. This characteristic is essential for electrical installations where tight bends or conforming to structural elements may be required.

The other choices do not apply to pliable Type ENT raceway. It is not composed of heavy metal, which would contradict its lightweight and flexible nature. Additionally, the raceway is inherently designed to be flexible, making it unnecessary for it to be rigid or requiring heating to bend. Thus, the specific feature of being able to bend by hand is what distinguishes a pliable Type ENT raceway, facilitating easier and more efficient installation processes.
