Tool makes preloading the torsion springs on the awning very easy.
The tool is very solid and you get 3 different ends that will adapt to the kind of awning you have. It worked very easily, but even at half what I paid I would still consider it quite expensive for what you get. It is not a precision tool, just a hand crank.
Why is the tool aluminum?
When I used this to adjust my torsion bar on my Dometic awning of only 12 feet wide, the crank arm actually started to bend. I couldn't believe it until I realized the crank is nothing more than aluminum. Why wouldn't they make it out of steel I asked myself? This can make for a very, very dangerous situation if the crank were to break away.
I got all the correct directions from Dometic before I started to adjust the torsion bar; so my adjustments were to their spec's.
I would not lend this crank handle to anyone for I'm worried they would hurt themselves not knowing that the crank will start bending.
