For the frame installation, we have set up the "Four-Sided AT Frame" suitable for both indoor and outdoor use, and the "Three-Sided AT Frame (Barrier-Free Type)" suitable for indoor installation only. Regarding the Three-Sided AT Frame, depending on the sound insulation grade (T-4 grade and T-3 grade), it features a door bottom that seals the gap between the door and the floor when closed, combined with a dedicated airtight material.
