  • Telescopic arm
  • For workbenches and small working areas
  • Maximum reach of 2.5 m

A wall-mounted telescopic extraction arm with counterweight and a rotable hood. Perfect for horizontal welding positions.

The T-Flex with counterweight is a wall-mounted telescopic extraction arm with a rotatable hood. Incorporated into the hood is a throttle valve that can be fully opened, partially opened or completely closed to control airflow at hood opening. The arm features a focus extraction spoiler, which directs the air into the hood.

Recommended for

  • Workbenches
  • “In position” welding


  • RotaHood 360-degree friction-free rotatable extraction hood for easy positioning
  • Light impact resistant industrial plastic tubes
  • All movement of the arm is controlled from the hood


The extraction arm is based on a telescopic tube with counterweight mechanism, allowing it to be extended to give a 8.2 ft (2.5 m) working radius and compressed to 5 ft (1.5 m). The arm is fitted with a spring balance which enables it to be moved from a vertical to a horizontal position in one easy movement. If mounted on a column, the arm can be turned through 300° due to the rotating hinge. All movement of the arm is controlled from the hood.

This arm needs a partner in crime

The T-Flex with counterweight can be attached to the following units:
