Wall-mounted handrail system with a minimalist and balanced Japanese design
The Comenza Sekkei ST-354 system is a wall-mounted handrail solution designed exclusively by Ryosuke Fukusada. Its design combines a circular base with an “L”-shaped arm, creating a visually balanced piece that conveys both strength and delicacy.
Made of stainless steel, the ST-354 is designed to blend seamlessly into architectural spaces where the handrail not only serves a safety function but also enhances the overall aesthetics. It is also compatible with the Ø43 mm RP-1430 round tube, ensuring consistent integration within Comenza’s handrail range.
01. BALANCED DESIGN WITH CIRCULAR BASE AND “L”-SHAPED ARM
The geometry of the ST-354 combines a circular base with an “L”-shaped arm, creating a piece with clean lines and balanced proportions. This design allows the bracket to blend naturally into the wall, delivering a refined aesthetic that reflects the influence of Japanese design and reinforces the visual identity of the Sekkei Handrail range.
02. SECURE GRIP WITH A STRONG AND DURABLE SOLUTION
Made of stainless steel, the ST-354 provides a strong and stable solution for wall-mounted handrail installations. Its design ensures secure fixing of the entire system, helping to improve safety and user comfort. In addition, the system complies with the safety requirements established by the Spanish Technical Building Code (CTE), ensuring reliable performance in the project.
03. EASY INSTALLATION WITH ACCESSIBLE FIXING POINTS
The ST-354 has been designed to simplify wall installation. The arrangement of the holes in the base provides easy access to the fixing points during installation, simplifying the installer’s work and enabling precise, fast, and secure positioning of the bracket.
