Telescopic spindle extension for installation in sidewalks and streets, mounted Helnor floating street box of type XB (sheet 1.910). Spindle extension and gate box are connected by means of a bayonet groove in the gate box.

Helnor telescopic spindle extension does not transmit pressure loads and therefore prevents breakage of the tap or water pipe. Terrain changes can take place without cutting or splicing the spindle extension.
If a too short length is chosen, the joint can be mounted without excavation and extra work.

During backfilling, lateral forces must be avoided and the function checked several times. By rotating the outer and inner plastic pipes 90 degrees to each other, the friction is increased, and they remain at the desired height during assembly. The telescopic tube cannot be pulled out of engagement for the maximum length.

The spindle is made of galvanized steel pipes that can withstand a torque several times the force required to close and open the valve.
The spindle sleeve is made of zinc-coated ductile iron and the plastic parts are made of impact-resistant polypropylene.

The spindle sleeve is pre-drilled as an extra safety for mounting the included stainless and acid-resistant split pin.

The spindle top is made of ductile iron GGG40 and is zinc coated. In order for the protruding spindle top not to cause damage to people and machines, it must always be mounted in the Helnor gate box.

The spindle top is adapted to Helnor key XN1 AND XN3 (sheet 1.900)
which in turn is adapted to a maximum torque of 9 kgm. This prevents the risk of overloading the spindle rod and valve.

Model XS fits on ground cranes of type:
Esco, Vulkan, Isiflo, AVK Norsk, T&D, PEL. Cimberio fits with the use of the valve’s supplied adapter. Frialen and Hawle can be used using a special adapter (Sheet 1.190). Using adapters, ground cranes of various other makes can be connected.
