I used Keith Christophers awesome and simple track saw rail end protector and made a an opening on the bottom so a rail clamp could be used while the protector remained on the end of the clamp.
I wanted an end cap for 1)protection from dings and dents, but more importantly 2)to prevent my vacuum hose from getting snagged on the end of the rail.
I also added a milwaukee Emboss and a right side and left side indicator.
The author remixed this model.
