Which term describes the device used to calculate the angle of a staircase during installation?

Explanation:
Determining the angle of a staircase during installation is done with an angle chart. This tool lets you translate the measured rise and run of the stairs into the incline angle, so you can set the equipment to match the stairs precisely. Knowing the exact angle is essential for proper alignment, railing height, and safe operation of the escalator or moving walk. The other items serve different purposes: a measurement sheet is for recording dimensions, not calculating the slope; chassis installation refers to mounting the main structure; and installation brackets are hardware components used to attach parts together.
