Tilt-Before-Turn Child-Safety Lockable Window

Tilt-Before-Turn Child-Safety Lockable Window Systems Overview | BLOSSOM CHEER

Engineered for schools and hotels, our Tilt-Before-Turn windows prioritize 15-degree safe venting while requiring key authorization for 90-degree opening, eliminating high-rise fall risks.

Key Benefits of Safety Lockable Tilt Before Turn Windows | BLOSSOM CHEER

Tilt-Before-Turn Sequence Restricting Direct Full Opening

Rotating the handle 90 degrees activates top tilt for venting; key unlocking is required for 180-degree full inward swings for safety.

Integrated 100mm Sash Restrictors Resisting 1,000N Push Loads

Heavy-duty stainless limiters cap openings at 100mm, preventing child falls and fulfilling international high-rise safety mandates.

Master-Keyed Authorization Mitigating Property Owner Liabilities

Guests operate tilt venting freely, while maintenance staff hold keys for full opening, eliminating high-rise liability claims.

Reinforced Anti-Drill Lock Cylinders Resisting 50Nm Torque

Hardened lock cores and heavy-duty zinc chassis withstand 50Nm wrenching forces, preventing unauthorized bypass of safety restrictors.
