Good morning, I have to tell you that the product, in my opinion, has a problem. The shackle does not pass through the respective shoe.
However, it is something that can be solved simply by filing a little the part that protrudes too much of the shackle to be able to pass it through the hole of the shoe.
However, for me it remains an excellent service that the SVB catalog offers, I have ordered often and will continue to order and read the in-depth articles published for the products.
