Window part

3/8" Spiral Window Balance for a Non Tilt Window
The spiral window balance is installed in an older aluminum non-tilt window. The metallic cylinder length is 25' and the diameter of the cylinder is 3/8. I do not see any bracket that attaches the balance to the window panel. The plastic tip appears to be red.

Green Tip Series 400?
Diameter is 3/8", length of the tube is 25". I believe I need the 400 series but there is no tip color option? Current tip is green. The second photo shows what the spiral attaches to at the base of the sash. Do I need to purchase anything other than just the spiral balance?
