JM129-B34

This is the outside diameter of the tube recommended for optimal use of the fitting. As a result, the B34 fittings are designed for tubes with an outside diameter of 33.7mm. This allows the screw to attach itself to the tube. Permissible outside diameters must be between 32 and 35mm to suit B34 fittings.

The B34 fittings cover the tube an average of 2cm , this may differ slightly depending on the model of connection. Refer to the technical diagram available on each product page, below the product description.

It depends on the type of tubes used as well as the thickness. As a precaution, we recommend a reinforcement every 150cm** (1.5m) with the EN 10255 33.7mm (3.2mm) galvanized steel tube. This allows the tube to maintain its load capacity in a horizontal position.

Permissible outside pipe diameters must be between 32 and 35mm for proper fastening. If your tube is not in this range, the screw may not touch the tube properly.

To attach the fittings to the tube, simply use a suitable allen key and screw. For professional use with public contact, it will be necessary to use a ratchet and to set a torsion torque of 40Nm *.
