The Fibramérica FAB-RS-M03 is a manhole and handhole chamber designed to protect underground fiber optic network connections, providing space for cable slack and splice closures and access for installation and maintenance. The chamber is constructed from interlocking SMC panels with transverse and vertical reinforcement, and its modular, lightweight design supports on-site assembly and manual handling. The technical specification lists B125 and C250 load-bearing configurations, both measuring 1520 × 520 × 642 mm, with axial test loads of 125 kN for B125 and 250 kN for C250 and a lateral test load of 40 kN for both. The required load-bearing grade and installation conditions should be confirmed when requesting a quotation.
