Air Tight Lever / Air Tight Handle

The Air Tight Lever is an important hardware component used on many ISTIQ Acoustic Doors to improve door sealing and overall acoustic performance. When the door is closed, the lever provides firm compression between the door leaf, frame, and seals, helping to reduce sound leakage through small gaps around the door.

In acoustic door design, even a small gap can weaken the actual sound insulation performance. A good compression handle helps the door seal more tightly and consistently, especially for applications where better noise control, speech privacy, or equipment noise reduction is required.

ISTIQ uses high-quality Air-Tight Levers because they are not only functional but also sleek, durable, and professional in appearance. The design gives the acoustic door a cleaner finish while maintaining reliable operation for frequent use.

This product is suitable for acoustic steel doors, acoustic timber doors, and other door systems that require proper sealing pressure. For clients who want better acoustic performance and a more refined door finish, the Air Tight Lever is a practical and valuable upgrade. Click below to learn more
