The Adjustable Mark II Mast Sliders for Stretched Canvas will adapt your original Mark II Mast to fit canvases up to 2" thick.  

Watch a brief setup video of the Mark II system here. 

Note: If you are ordering the sliders separately from the Mark II Mast, you may need to customize the fit to your particular mast once you receive the sliders.  Check out this video for tips  https://www.youtube.com/watch?v=ygNmeszxRcI
