Low or level threshold designs allow equal floor finish levels inside and out, whilst maintaining full weatherproofing. Visually, the effect is stunning.

The bottom of each door section has its own long wheelbase solid aluminium carriage with four wheels that run inside a low threshold base track.

The door comes with a bespoke ‘finger safe’ gasket between each door leaf, which ensures there is no gap for little fingers to get trapped in.
