45 mm (1.75 inches) 

long process

For coarse or sticky 

materials. The material 

stuck to the blade tends 

to affect the operation 

of the unit less.

 

 

More robust due to the 

blade’s small area and 

insertion length.

 

 

 

Can be inserted even through a 

1", 90 mm (3.5 inches) long 

process connection. 

 

Paddle cannot be used with 

sticky materials, as they may 

prevent the blades from closing 

when removing.  

 

The blades must be closed by 

pressing the blade tips together 

when the unit is installed. 

 

For materials with a larger 

specific weight. 

 

 

By pulling it over the cable rope, 

it makes units with cable rope 

extension stiffer. 

 

Caution! If the cable rope is 

shortened, the tube must be cut 

to a matching length. 

The length of the exposed cable 

rope section must be at least 30 

mm (1.2 inches).
