Frog hinge (non perforated hinge) adjusts the opening and closing angle of the door panel by adjusting the spring force or hydraulic system, mainly used to solve cabinet door installation errors, differences in usage habits, or scenarios that require special opening and closing angles.  

Adjust the purpose

Installation error correction: There may be positional deviation between the cabinet and door panel during installation. By adjusting the hinge angle, the error can be compensated to ensure perfect alignment between the door panel and the cabinet.  ‌

Personalized opening and closing requirements: Some users prefer to adjust the cabinet door to a specific angle (such as a 45 ° pause display), or to close slowly throughout the entire process (such as a three-stage force hinge). The frog hinge supports flexible adjustment to meet different needs.  ‌

Safety optimization: After adjustment, the door panel can be paused at a safe angle (such as 30 ° -45 °) to avoid the risk of hand pinching, especially suitable for families with children or elderly people.

adjustment method

Spring force adjustment: Some models change the buffering force by rotating the spring adjustment knob, which affects the angle at which the door panel stays.

Hydraulic system fine-tuning: Some high-end models support more precise angle adjustment through hydraulic rod stroke control.
