When you open this package, you will find your prosthetic cover in two- anterior and posterior parts, screws and a hex key.
Put the anterior part on your prosthesis tube.
Put the posterior and the anterior details together, carefully match joining points of both parts. Gently press and hook them.
Put screws in the holds and start screwing. Align both parts by putting them in the right position and then finish screwing. But not too tight, avoid damage of internal threads.
