SEBO Telescopic Tube Locking Mechanism for AIRBELT D1, E1, E2, K2, C1.1 and C2.1

A wand that sinks under its own weight while you are working has lost its catch, not its tube. Part 6238ER is the spring-loaded locking mechanism inside the telescopic wand, the piece that bites when you let go of the collar and holds the two sections at whatever length you chose.

The catch wears at its engagement face and the spring behind it tires, so the tube creeps shorter mid-stroke or refuses to lock at all. A wand that locks in some positions but not others is showing the same wear from a different angle. Renewing this part costs far less than a complete wand and takes a fraction of the time, which is why it is worth diagnosing properly before ordering steel you may not need.

SEBO shows the component at position 37 in the AIRBELT E diagram and position 52 in the AIRBELT K diagram. On the K sheet it sits directly after the stainless steel tube at position 50 and the sliding knob at position 51, which is a fair description of how the assembly works: the knob is the external control, this catch is what it releases, and 1736GS at position 54 is the fitting neck on the end. Those three numbers share this part's fitment exactly, so a wand can be rebuilt from them without guesswork.
