1/2" Power Twist Plus Link V-Belt，4FT Power Twist V-Belt 1/2-Inch x4 Feet A Type，V Belt Adjustable Link Perfect for Lathes, Table Saws and Other Woodworking Tools (Red)

These are great! I needed a replacement v-belt, but I wanted one a little shorter this time. It took a little practice to be able put this together, but once you figure it out (5min) it's really easy! I was able to make the length exactly like I wanted. Its also quieter than the old v-bel that made noise because of the joint. Seems really durable, I expect it to last a long time, especially because it is so forgiving of minor alignment issues. It also flexes enough that my saw motor doesn't jump anymore!
