What it is
The Fischer SF 31 saddle bracket is a connecting element for support systems with an A M8 thread and a 13 mm tightening spanner size, with a T-inst tightening torque of 10 N·m for controlled installation. It carries a maximum recommended shear load of 1.5 kN and a recommended shear load V-Rd of 1 kN, values suited to building-services use. It is supplied in boxes of 10.
A bracket is a cantilevered support in steel, cast iron or nylon, fixed to the wall, that carries a load resting on or hanging from it: a radiator, a washbasin, an expansion vessel, a shelf or a pipe.
What it is for
Used for installing building services and plant and for supporting pipework and ductwork.
How to use it
Mark the position and check with the spirit level before drilling. Fix with anchors suited to the wall and to the weight to be supported, using all the holes provided. For radiators and sanitaryware, space the brackets at the stated distance so that the load is evenly distributed. Before loading, check that it is tightened firmly and level.
