As seen in Guitar Girl Magazine June 2018 issue.
The CINCH FIT is a clamp designed to make fitting ordinary straps over endpins easier by use of a Cinch-style clamp. Once you loop the CINCH FIT chord around one end of your guitar strap, you simply pull the cinch clip apart setting over the endpin and draw it closed by pulling on the cord. The strap is now securely connected to the endpin. Once you have completed this strap on the other end pin, you are ready to put the connected strap around your neck and play your guitar! This particular device we tried was designed specifically for Taylor Guitars and may not be a good fit for other guitars, so be sure and check the specs for your particular guitar before purchasing. $14.99
