LAS4014 si Threshold Plate

Stepped plate

The LAS4014 si threshold plate is a robust, aluminum threshold solution, suitable for use on fire-rated steel doorsets. Featuring a high-performance silicone compression seal, the LAS4014 helps prevent the penetration of rain, draughts, light, and noise, enhancing the comfort and protection of interior spaces. Its stepped design increases the effectiveness of threshold seals by creating a firmer gasket contact, while the durable anodised finish provides a sleek and resilient aesthetic.
