The stainless steel Lean Duplex grout-in bracket JMK+ NA is available with load levels of 3.5 and 7.0. The rated resistances are accordingly FRd = 4.7 kN or FRd = 9.5 kN. The condition and load-bearing capacity of the substrate must be checked in advance. The compressive strength of the existing masonry must be at least 2.1 N/mm2 and the wall thickness at least 240 mm. If the compressive strength is lower or walls are thinner, a special solution must be developed. The JMK+ NA is available in cantilever lengths of 110 to 330 mm.
