1) Function: Ground springs are necessary for installing larger glass doors (such as sliding doors and large doors). 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) at the corresponding position of the door bottom.
2) Specification: The specifications of the ground 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 (which adjust the rebound speed of the door by adjusting the measurement size). But remember to make slight adjustments when adjusting the screws, and never adjust them too forcefully or excessively at once. Otherwise, it may cause excessive oil overflow. Ultimately destroying its functionality.
The following are three specifications of ground springs: (taking SOB as an example)
Ground spring model applicable door specifications
Door leaf size: width * height (mm) Door weight (kg)
SOB-2201 (Light) 1000 * 2200 100-120
SOB-2202 (Medium) 1100 * 2300 105-130
SOB-2203 (Heavy duty) 1300 * 2600 130-180
3) Selection items: When selecting floor springs, according to the specific structure and decoration of the door body and door frame, matching accessories such as upper and lower door clips, top clips, curved clips, lock clips, etc. should also be selected. The specific situation is as follows:
- Wooden door frame, glass door wooden frame, only need to use straight and bottom clips.
- If the glass door frame has no frame, upper and lower clips (top clip or curved clip) must be used.
- Lock clips are generally suitable for glass doors without wooden frames.
