These blocks will fit all sizes of Kromski Harp loom.
Fixes into the predrilled holes on the loom frame.
These are intended to be added to older Harp looms to allow the use of a second heddle.
Later Harp looms have a double heddle block system fitted as standard. A second heddle block is not needed.
Having a second heddle allows simple patterns in the weave to be produced.
