Junction function
insPIRe® U hidden lock = premium alternative to the visible S lock. The key difference: the fastener disappears behind the facade, concealed within the lock geometry.
Vs. insPIRe® S:
| Feature | insPIRe® S | insPIRe® U |
|---|---|---|
| Visible fastener | yes (in the panel face) | no (in the lock) |
| Modular width | 1000/1100 mm | 1000 mm (fixed) |
| Fasteners per width | min. 3 | min. 2 (through PM1) |
| Aesthetics | industrial | premium (smooth facade) |
| Price per m² | base | +12-18% |
| Typical use | warehouses, production halls | car showrooms, office buildings, eco-buildings |
Available thicknesses: 40, 60, 80, 100, 120 mm.
Critical installation aspects
- U-lock geometry is deeper than in S — accommodates PM1 + fastener head.
- Fastener fixed EXCLUSIVELY in the lock through PM1.
- Modular width 1000 mm is fixed.
- The “tongue” side always faces the prevailing wind direction.
- PUS gasket factory-fitted — airtightness class 1 acc. to PN-EN 14509.
