THE ORANGE WEDGE: FS REVOLUTION
We created this wedge years ago because it's so dangerous making timber ones (planing all those strips, wrapping them up in blocks of eight, cutting them and then cutting them again into wedge shape. You get the idea!) plus the timber ones shrink with age and fall out. I know it's plastic, so LOOK after them and they will last forever!
No need to work out how many you need because they are included in the price and will be packed with your stretcher bars and frames. If you need extra then they are 45 cents each.
