Glimakra makes two 12.5" low profile shuttles, this one is a damask. It is a 12.5" low profile shuttle that is just 1/2" high. Takes a 5" quill.
If you have a drawloom or weave on a table loom with narrow sheds, consider purchasing a damask shuttle. They are only 5/8" tall and will weave through very small sheds. They are useful for weaving on table looms, double weave and pick up weaves. Damask shuttles only work with quills.
