LAS4010 Lorient Aluminium Threshold Plate - 2.1m

The Lorient LAS4010 Aluminium Threshold Plate - 2.1m is a low-profile aluminium threshold plate designed to provide an even surface underneath a door and is suitable for wheeled traffic.

The LAS4010 has a 75mm 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 LAS4010 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.

Can drop down seals be cut to fit the width of a door?

Yes, many drop-down seals and automatic drop seals can be trimmed to suit the width of the door during installation. The amount that can be cut will vary depending on the specific seal model and design. For detailed trimming allowances, fitting instructions and installation guidance, please refer to the product datasheet for the particular drop seal you are installing. Following the manufacturer's instructions will help ensure the seal continues to perform as intended for acoustic, smoke and fire door applications.

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.

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.

What is the minimum and maximum gap size for the FAS45 Rebated Drop Down Seal?

The FAS45 Rebated Drop Down Seal is designed to seal gaps between the bottom of the door and the floor or threshold, ranging from 3mm to 13mm. This operating range helps the seal provide effective acoustic performance, smoke containment and draught reduction when the door is closed. The FAS45 is a rebated automatic drop seal that self-levels to the floor surface, making it suitable for a wide range of door installations. Always refer to the product datasheet and installation guidance to ensure the seal is suitable for your door set and application.
