Multi-Point Lock Systems for Aluminum Windows and Doors
Multi-point lock systems improve project security and can support air-tightness when matched with proper gaskets, glass, frame design, and opening style. We confirm the hardware package from the opening schedule instead of quoting lock parts in isolation.
What to confirm before choosing lock points
- Opening style: casement / tilt & turn / hinged door / other
- Locking points: requirement or preference
- Security need: residential / commercial / project
- Glass: laminated/tempered options if required
- Seals: standard / upgraded
- Exposure: coastal / high wind / high-rise / heavy-use corridor
Hardware RFQ checklist
For a clean quotation, send the opening schedule together with the hardware expectation. The most useful information is product line, sash size, opening direction, target lock points, handle or cylinder preference, gasket level, glass build-up, and whether the project also needs weather-security or high-wind confirmation.

Lock-selection matrix for project buyers
| Use case | What to confirm | Why it affects quotation |
|---|---|---|
| Casement windows | Sash size, handle position, target lock points, gasket level | Locking pressure and seal compression depend on sash geometry. |
| Entrance doors | Cylinder, handle, hinge, lock body, usage frequency | Security and durability requirements can change the hardware package. |
| Balcony or coastal doors | Exposure, corrosion expectation, glass build-up, threshold detail | Coastal and high-use areas may need upgraded hardware direction. |
| High-wind projects | Wind pressure, opening size, reinforcement, weather seal expectation | Locks should be reviewed with frame, gasket, glass, and reinforcement. |
