Drop Seals for Pivot Doors
Sealing pivot doors at the threshold presents unique challenges. Unlike traditional hinged doors, pivot doors rotate on a central or offset pivot point, which can create larger or uneven gaps at the top and bottom. With narrow door leaves and sleek, modern designs, these doors need discreet, effective sealing solutions that don’t compromise aesthetics.
Introducing the Planet US Pivot Module Set - a complete sealing solution for rebated pivot doors.
The Planet US is an ultra-slim drop seal, just 8mm wide, making it ideal for narrow, minimal-profile pivot door leaves. The seal is mortised into the top and bottom of the door, delivering a discreet yet highly effective barrier against sound, smoke, draughts, and light.
Smart Engineering for Smooth Operation
Pivot doors experience significant mechanical forces due to their central or offset hinge position. To overcome this, the release mechanism of the drop seal system — including the roller and pivot ram — is installed on the lock side of the door. This configuration reduces the force required to activate the seal while improving door-closing dynamics.
As the door closes:
- The roller mechanism glides into the pivot ram (mitred neatly into the frame), guiding the door gently into position.
- The top seal retracts, and the bottom seal drops, creating a full, reliable seal along the entire width of the head and threshold of the door.
- The drop seal can also be installed on just the threshold of the door, depending on requirements.
This design compensates for sloping floors and uneven thresholds, offering high-efficiency sealing with silent, low-resistance operation, even across gaps of up to 20mm.
Stylish and Functional Finishes
The exposed roller module is available in brushed stainless steel or a black finish, offering flexibility to match contemporary door hardware styles.
