After he places the head tefillin  on the head, as we said, till the end of the hairline, and here  he places the knot on the bone, he adjusts the two  straps in the front, you must be careful that the  head straps do not twist and that the black part  should be pointed out, he should adjust the two side  straps and straighten them, putting them in his belt  or pants with a certain fold, securing them so that  the straps are straight during the course  of his prayers, and then he takes  the hand tefillin and moves them from the strappings  on the arm to the middle finger, starts off strapping one turn  on the middle knuckle, and two turns on  the lower knuckle, comes back around  from here and transfers whatever  is left to the hand and tucks in the edge so  that it holds it in place and doesn't come apart during  the course of the prayer.
