This is in another way to do it:

 


Hi Cirox,
 
You can constrain the shape by doing a little math...

var offset = this.x * Math.tan(45 * Math.PI / 180);
TweenLite.set(drag, { width: this.x, height: offset });
TweenLite.set(handle, { top: offset });

But an even easier approach would be to do it as a ratio. 45 degrees would be 1:1, so just set the height and width equal to each other.
TweenLite.set(drag, { width: this.x, height: this.x });
TweenLite.set(handle, { top: this.x });
