Lorient LAS4002 Threshold Plate – 2.1m
The Lorient LAS4002 Threshold Plate (2.1m) is a high-performance aluminium threshold solution designed to enhance fire, smoke and acoustic sealing at the base of doors. Engineered for use with automatic drop seals and perimeter sealing systems, it provides a durable, level surface that helps maintain the integrity of fire-rated and acoustic door assemblies.
Manufactured to Lorient’s exacting standards, the LAS4002 threshold plate improves seal contact against uneven floor finishes, reducing sound leakage and limiting the passage of smoke in the event of a fire. Its low-profile design ensures compliance with accessibility requirements while offering long-term durability in high-traffic commercial and public buildings.
Key Features & Benefits

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.
Do drop seals 'Self Level'?
Yes, Drop Seals self level to the floor's surface. Threshold plates can be ued to create an aesthetic finish or provide a flat contact area on uneven and irregular floors surfaces.
