The mechanisms of the SUNDIY system are securely fixed to the structure (whether wood, aluminum, concrete, etc.) using fastening clips* that must be screwed in beforehand. The screws offered here are specifically designed to ensure effective fixation in WOOD.
Regarding the calculation of the required number of screws, it is recommended to use between 4 and 6 screws per pair of mechanisms.
*The CLIPS are INCLUDED with the SUNDIY mechanisms.
