Anti-Drop Safety Design
Tailored for every sash weight, the top hinge uses a hook-in profile that grips tighter the heavier the sash becomes.
The assist cord is the extra margin of safety our engineers wove in.

Inside its tensioner, a custom-shaped spring—anything but ordinary—delivers superior load-bearing strength.
It prevents secondary sash sag while the cable itself holds a static load of 550 kg.

Multi-Point Locking System
The corner drive’s suspension support employs a C-pin plus screw double-fixing structure, reinforced by a lateral brace to stop sagging.
In tilt mode, the bottom hinge’s gear-type limiter is anchored with three screws into the sash—wind can’t slam it shut; only controlled strength remains.


Dual-Suspension Safety Module
Two independent suspension points raise the safety ceiling.
The corner drive’s new anti-misuse mechanism features an internal U-shaped flat spring, delivering stronger rebound and crisper anti-misuse action, eliminating jamming and easing reset.
The top hinge’s eccentric, multi-dimensional sealing pin is sculpted for ergonomic adjustment—comfort engineered down to the fingertip.




“We don’t design hardware; we design the unspoken sense of security that keeps every window of every home quietly lit.”
