BG451016410 You don't say what sort of equipment your "Wolfcraft guide rail" is intended to work with. I have looked online and the only Wolfcraft "track" I can find relates to a system for attaching a circular saw to a "Wolfcraft guide rail" and on that basis it seems unlikely that the item will fit your Wolfcraft track if it is that system you have as the item is intended to fit onto track saw rails accompanying track saws which are specifically made to fit onto the track saw rail that their manufacturer provides, However. the following general information should be of assistance. If the track you have is compatible with one of the track saw tracks produced by any of the following manufacturers the item will fit: Festool, Triton, Scheppbach, Makita and all track saw rails that are shaped like the Festool rail. I am using it with a Makita track saw track and it works perfectly. To help people with questions like this the situation is that Festool and Makita are the main quality brands whose tracks will fit this item - all you need to do is to "google" whether your brand of track saw is compatible with the Festool or a Makita track or track saw and if it isn't this item will not fit.
