There is a notation on the picture that it will come with a straight plug, instead of the angled plug.
This is a great plug on the END. But, the manufacturer intends for you to use this big bulky plug solely as a splice to connect to your cord. Then I won’t roll up smoothly. On amazon, some reviewers cut it off and wired their cord straight in. OR, it should be a very short lead, less than a foot, with a small plug, so that another cord can wind.
