The Leclerc tension box is used with the Sectional Warp Beam and is adjustable to fit any Leclerc floor loom. The tension is adjustable for uniform tension on all warp ends as they are wound from the spool rack to the loom.
Two open 12 threads per inch (4.8 / cm) combs allow easy threading and help guide threads into the proper section. This weaving tension box can also be used with an optional counter when filling bobbins, to give the number of meters or yards on bobbins.
Fits into breastbeams 1.5 - 3.25"
