Shipping: Yu-Packet Post mini (planned) (Supplementary Information) D'Addario's CinchFit is a convenient item that allows you to easily and securely attach and detach a strap to a guitar with an endpin jack. It helps prevent common accidents such as the strap coming off during a performance due to forcing the strap hole to fit, causing the guitar to fall, or scratching the guitar by leaving the strap on while putting it in the case or changing strings. There are several items of this type, but I feel that the CinchFit is the best, and I have been using it repeatedly. CinchFit is sold in two models: one suitable for guitars like Gibson (PW-AJL-01) and one suitable for Taylor guitars (PW-AJL-02). This item is the latter, the Taylor model (PW-AJL-02). I bought it on Amazon thinking it might work with a mysterious guitar I own, but it didn't fit, so I'm putting it up for sale. Therefore, it is in near-new condition. There isn't much information online about the difference between PW-AJL-01 and PW-AJL-02, but after observing the actual product, I found the following. The only difference between the two models seems to be the diameter of the hole that clamps the endpin jack (see Figures 3 and 4). Using calipers, I measured the hole diameter of PW-AJL-01 to be 12.2mm and the hole diameter of PW-AJL-02 to be 8.2mm.
