Structural Engineering Details, Fleet Compatibility & Field Performance
Solving Non-Standard Elevations with SM-F650 Clamp-On Rosettes
When refinery pipe racks, soffits, or irregular balcony slabs fall between fixed 50 cm rosette intervals, the SM-F650 clamp-on movable rosette (1.5 kg) bolts anywhere along a Ø48.3 mm tube to create an instant 8-way Ringlock node.
Wedge-Head Couplers: Bridging Ringlock Rosettes with Standard Ø48.3 mm Tubes
Combining a cast Ringlock wedge head on one side with a drop-forged Ø48.3 mm coupler on the other, SM-F648 (fixed) and SM-F649 (swivel) connect lattice truss beams, tie pipes, or tube-and-coupler extensions directly into a rosette port. The twin-wedge SM-F652 (1.4 kg) locks two adjacent vertical standards side by side for doubled column capacity.
Crane-Lifting & Uplift Safety with SM-A656 / SM-F657 Locking Pins
Whenever assembled Ringlock stair towers, shoring tables, or cantilevered sections are lifted by crane—or exposed to wind uplift on high-rises—SM-A656 Ø12 mm spring pins or SM-F657 U-locking pins secure the vertical spigot joints against tensile separation.
