1) Function: To install large-sized glass doors (such as sliding doors and large doors), floor springs must be used. Its main function is to bear the weight of the door, control the opening and rebound of the door. Installed on the ground (slotted and buried) and at the corresponding position under the door.
2) Specifications: The specifications of the floor spring are also based on the size and weight of the applicable door. Its opening and rebound force are achieved by the hydraulic pressure of the liquid in its components. Therefore, the internal components of the ground spring are equipped with speed regulating screws (to adjust the door rebound speed by adjusting the measurement size). But remember to adjust the screws slightly, and never adjust too much or too much at once. Otherwise, excessive oil overflow may occur. Ultimately destroying its functionality.
The following are three specifications for ground springs: (using SOB as an example)
Floor spring model applicable to door specifications
Door leaf size: width * height (mm) Door weight (kg)
SOB-2201 (lightweight) 1000 * 2200 100-120
SOB-2202 (medium) 1100 * 2300 105-130
SOB-2203 (Heavy Duty) 1300 * 2600 130-180
3) Selection matters: When selecting floor springs, according to the specific structure and decoration of the door body and frame, matching accessories such as upper and lower door clips, top clips, curved clips, lock clips, etc. must also be selected. The specific situation is as follows:
1. Wooden door frames, glass doors with wooden frames, only need to use straight and bottom clips.
2. If the glass door frame has no frame, upper and lower clips (top clip or curved clip) must be used.
3. Lock clips are generally suitable for glass doors without wooden frames.
