Join us as we explore a new quote each week, reflecting on 40 years of innovation!
“Tensioning big torsion springs has since history been done with two iron bars. Making it a job with ‘health and safety’ risks. Not only dangerous, but also with possible long-term muscle injuries for the mechanic. ISTT is clearly a safe, time-saving and healthy innovation, leaving the hard part to a powered drill bit.”
The popularity of the ISTT and the ISTT-GO trolley resulted in additional demands from our customers. To follow this up, we introduced an ISTT-125 for doors equipped with a 1 1/4″ shaft. Besides that, we offer some spare parts for the device: the ISTT-PEN-A (for 2″ and 2,62″ springs) and the ISTT-PEN-B (for 3,75″ and 6″ springs).
This way the health and safety advantages of the tool are made available for all doors!
For a demonstration of the ISTT, you can check the video below:
