Modular Aluminum Framing Profile System (45×45 mm, 3842529287)

This is an aluminum structural profile from the Bosch Rexroth strut profile system, a modular framing system for machine bases, guards, workstations and conveyors. The 45×45 section has T-slots on four sides and a central bore for threaded connections, extruded in aluminum alloy. Profiles are cut to length and joined with the system’s connectors, angle brackets and T-nuts, with no welding, so assemblies can be built, changed and reused. Accessories include panels, hinges, casters and linear guides.
