Good Morning,
Thank you for your patience. I am currently in the process of researching possible replacement rollers. I will post an update as soon as I have more information to share.
This particular style roller with the T-tab design has been discontinued by Del Mar. We are still working on possible substitutes for you.
The part is a Del Mar Eng Patent #3,670,357, it also has the #1 stamped above the name. 2-3/16 l x 1-1/2 h x 3/4 w.
Thanks for posting! I placed your inquiry in an existing discussion regarding the Del Mar Eng Patent #3,670,357.
