2 studs
4 studs
Application
• Fastening of cable trays, pipes, on a horizontal cantilever support, fastened on
a vertical structure
• Support is fastened by two / four X-BT-MR on both support and brace
baseplate with distance x
• L1 is the distance of the load center to the vertical structure surface
• Load F is the acceptable total load (all dead load including)
Boundary conditions
• These values are ONLY reflecting capacity of X-BT-MR threaded stud.
Structural analysis of support / structure is NOT in Hilti scope. See the
detailed statements in disclaimer — 2018/05/04
• Shear load fully carried by one / two top X-BT-MR (worst-case)
• Load F acting at the distance of L1 from structure surface
