It will work with other tools if they have a place to clip it on.
The installation instructions that came with the strap are adequate, although they could certainly be better. To install the strap, the trimmer head has to be removed from the shaft. I also had to remove the handle to get the strap fitting higher on the shaft. Then, replace the handle and trimmer head, find the balance point on the shaft and tighten the strap attachment there. That's all there is to it. It must have taken me about 15 minutes.
This was an online order not available at my near by stores
