LAS4011 Lorient Aluminium Threshold Plate - 1m
The Lorient LAS4011 Aluminium Threshold Plate - 1m is a low-profile aluminium threshold plate designed to provide an even surface underneath a door and is suitable for wheeled traffic.
The LAS4011 has a 100mm profile width and is only 6mm high, providing a low-profile threshold solution. It features a silver anodised aluminium finish as standard and is supplied with fixing screws.
The threshold plate can contribute towards smoke, weather, draught and light containment when fitted with a suitable threshold seal. It can also increase the effectiveness of threshold seals by creating a firmer gasket contact.
The LAS4011 is suitable for use with practically any drop or door bottom seal and can be installed on single and double swing doors. Standard lengths are 1m and 2.1m, with other lengths available to special order.

Do drop down seals need to be used with a threshold plate?
No, drop-down seals and automatic drop seals do not necessarily require a threshold plate to function correctly. Whilst many drop seals are fire tested and acoustically tested with threshold plates, a threshold plate is not always required, depending on the application, floor finish and performance requirements. Threshold plates can help provide a consistent sealing surface and may improve acoustic, smoke or sealing performance in certain installations. Always refer to the product datasheet, fire test evidence and installation guidance to determine the most suitable configuration for your door set.
