Walker and Williams is a long time US crafter of high end leather goods that has been in business for well over 100 years and has recently started producing outstanding guitar straps. There have been a lot of requests for extra long versions of their premium straps and this is the solution. It's a longer replacement tailpiece for all of their double padded C series straps. The XL-72 extends the maximum length by 5 1/2'' from 55'' to about 60 . This extender can also be used with most of Walker & Williams G-series straps and will actually extend the G-series straps up to about 62''. The main difference between the XL-72 and W&Ws other strap extension, the XL-60, is in the quality and thickness of the leather. The XL-72 is also about 2 1/2'' longer than the XL-60. The size and width of both W&W extenders also happens to be the same as many other straps on the market that use the standard ''ladder'' type adjustment system, so it may very well fit other straps you already have. Here are a few of the many feedbacks we've received about the Walker & Williams straps: Awesome quality. Better than I'd hoped.Very happy. You WILL NOT find a nicer strap for the money than these.
