FAQ

What types of doors and environments is the Teboneng Hydraulic Door Closer suitable for?

It is suitable for most swing doors, including wooden, metal, and glass doors. Its design accommodates various environments, from standard indoor locations to harsh outdoor or industrial settings with moisture, dust, or temperatures ranging from -30°C to +60°C, while maintaining stable performance.

Can the closing speed of the product be adjusted? How is it adjusted?

Yes. It utilizes a high-precision hydraulic damping system and valve core precision control technology, supporting stepless adjustment of closing speed. Adjustment is typically done via the speed control valve (screw) on the closer, allowing precise speed control across a 0-180° opening angle range for smooth and quiet door closure.

What is the sealing and protection rating of this door closer?

The product features an innovative multi-layer sealing structure, using imported high/low-temperature resistant seals and a high-pressure die-cast aluminum alloy housing, achieving an IP54 protection rating. This means it effectively prevents dust ingress and low-pressure water spray from all directions, offering good dust and water resistance.

What are the main advantages of the Teboneng Door Closer compared to similar products on the market?

The main advantages lie in its core technological breakthroughs: high-precision hydraulic damping for smooth, shock-free stepless speed adjustment; excellent environmental adaptability (IP54, wide temperature range -30°C~+60°C); and a robust, durable construction (high-pressure die-cast aluminum alloy housing with imported seals) ensuring long-term stable operation even under harsh conditions, effectively reducing wear on doors and frames.

Is the installation of this door closer complicated? Does it require professional tools or regular maintenance?

The installation process is similar to standard door closers. It is recommended to be performed by professionals using common tools to ensure optimal performance. Due to its high-quality sealing structure and durable materials, it typically requires minimal maintenance under normal use conditions. Periodically check the mounting screws for tightness and clean the exterior housing.
