摘要

The hook has a base plate and a clamp that are connected by a double lock function. The clamp, the base plate and an angle anchor plate are connected with each other using screws and nuts, while fastening a solar module to the hook. The clamp is adopted into a corresponding retainer of the base plate with a mallet. A lower surface of the base plate is corrugated to hold the clamp at a roof rafter. The clamp has approximately 1415 millimeters length and 40 millimeters breadth, where all individual parts of the roof hook have a fixed wall thickness. Independent claims are also included for the following: (1) a base plate of a roof hook (2) a clamp with an angle anchor plate of a roof hook (3) a height adjustment of a roof hook.
