The leather cradle straps are wonderfully secure and safe for your banjo. Since they are made of leather, they will not mar the finish of the banjo as straps that have metal clips can do.
The cradle strap is made up of three pieces of leather. There is a long, broad, flat piece( made of leather or woven material like cotton cinch) that is connected to leather ends with adjustment slots. From there you will see that each end has a long thin piece of leather with smaller holes and a slender black shoelace. The shoe laces will be used at the end of the attachment process to bind the loose ends of the strap together. The 1” wide, thinner pieces of leather that will be threaded through the channel formed by the j-bolts/hooks that you will find around the rim of your banjo.
