Accurate measurement: Choose the appropriate type of floor spring series according to the size of the door leaf to avoid affecting the service life due to insufficient load-bearing capacity .
Correct slotting: The floor spring must be fully embedded in the ground, and the slot size must be accurate. Too large or too small will affect stability.
Horizontal calibration: During installation with door hardware accessories, ensure that the surface of the floor spring is flush with the ground, and use a plumb line to adjust the axis position to ensure verticality .
