The high-pile DUO is built for maker projects that need depth. It is a separate height variant, not simply an accessory to the low-pile model.
Why this model is worth considering
Taller pile from an electric cut-and-loop machine.
Important tradeoff
Consumes more yarn and sacrifices some fine detail.
Before buying
Compare the exact model, accessories, plug and seller support. An Amazon search does not guarantee that the referenced variant is available there. See the manufacturer or supplier reference linked below for documented specifications. This independent editorial profile is not a hands-on test.
