my spiral balance for my vinyl window appears orange. its a 3/8" tube diameter and a 29" length. The windows shouldn't be very heavy since they only measure about 31"x34" and are 5/8" thick insulated glass. Should I just order the red ones?

If the diameter of the outer tube is 3/8", I would recommend our S900-29 spiral balance.
