Norsound NOR832 Retro Fit Glass Door Bottom Auto Drop Seal

Norsound NOR832 Retro Fit Hinged Glass Door Bottom Auto Drop Seal | Glass 10mm | Under-Glass Mount | 15.4 × 27mm

The NOR832 is a single-actuation automatic drop seal designed for retrofit installation to the underside of hinged acoustic glass doors with 10mm glass thickness. It shares the same housing profile, actuation mechanism, and fixing method as the NOR830 and NOR831, but is specifically sized for 10mm glass. Maximum gap coverage is 11mm. The housing is bonded to the underside face of the glass door leaf.

The NOR832 housing is manufactured from aluminium with a silicone gasket, supplied in silver anodised (C 0) or stainless steel-coloured anodised (C 31) finish. The housing profile is 15.4 × 27mm. Standard lengths are 708mm, 833mm, 958mm, 1083mm, and 1208mm, with a 125mm cutback. Single actuation. Bonded with adhesive (not supplied). For 8mm glass, see the NOR830; for 8–12mm glass range, see the NOR831; for 20mm glass, see the NOR833.

Applications

• Hinged acoustic glass doors — 10mm glass, under-glass mounting — bond to the underside face of the 10mm hinged glass door leaf to seal the gap between the door bottom and the floor when the door is in the closed position. The housing channel is sized for 10mm glass, ensuring a correctly fitted bond and consistent seal alignment. Select the appropriate length for the door leaf width, accounting for the 125mm cutback at the actuator end.
• Retrofit installation on existing 10mm hinged glass doorsets — the bonded fixing method allows the NOR832 to be installed on existing glass door leaves without drilling or screwing into the glass.

Product Benefits

• Sized for 10mm glass — correct housing fit for underside bonding. The housing dimensions are matched to 10mm glass thickness, ensuring the seal seats correctly on the underside face and the bond line is consistent across the full length of the housing.
• 11mm maximum gap coverage. The NOR832 accommodates floor gaps up to 11mm, providing sufficient coverage for standard floor finish tolerances beneath hinged glass doors.
• Under-glass mounting — suited to hinged glass doors where edge mounting is not practical.
• Single-actuation automatic drop mechanism — consistent sealing on every close.
• Bonded fixing — no drilling into glass required.
• Five standard lengths — 708mm to 1208mm. The 125mm cutback accommodates the actuator mechanism at the end of the seal.
• Two finish options — silver anodised and stainless steel-coloured anodised.

Installation

Select the appropriate seal length for the door leaf width, accounting for the 125mm cutback at the actuator end. Clean the underside face of the 10mm glass door leaf thoroughly — the surface must be dry, grease-free, and free from contamination before bonding. Apply a suitable structural adhesive (not supplied) to the housing and press it firmly onto the underside face of the glass, ensuring correct alignment. Allow the adhesive to cure fully before operating the door.

Once cured, close the door and check that the actuator engages the door stop cleanly and the seal carrier drops to make full contact with the floor. Check that the carrier retracts fully on opening.
