The left inside/outside opening design eliminates restrictions on bathroom layout. The shaft uses a precision bearing system, ensuring quiet operation (≤30dB) to avoid disturbing family members or hotel guests.

The frame and shaft are made of 304 stainless steel (rust-proof) with an optional brushed or polished finish, matching modern bathroom aesthetics (e.g., minimalist, industrial, or luxury styles).
• Installation Resources: Provide 2D/3D installation drawings, video tutorials, and a dedicated technical hotline to assist manufacturers’ installation teams.
• Warranty Service: Offer a 3-year warranty on the shaft mechanism and a 1-year warranty on surface finishes, boosting customer confidence for manufacturers.
