NABCO NAT DOOR is an automatic sliding door with a sealing function. When the leaf reaches the fully closed position a lower packing descends automatically to complete the seal, and the door opens again with no residual clearance. The guide rail is flat, so the threshold stays barrier free for trolleys and wheelchairs. It is certified to JIS A 4702 for both air-tightness and sound insulation.
Key Features
- Automatic lower seal, the packing descends on full close and lifts before the door moves, so the seal never drags.
- Certified performance, JIS A 4702 Class A-3 and A-4 for air-tightness, Class T-1 for sound insulation.
- Barrier-free threshold, a flat guide rail that trolleys, beds and wheelchairs cross without a lip.
- Supplied and installed by Elite Radio, following a site survey, with installation covered in your project quotation.
