The Leclerc Tension Box is used with the Sectional Warp Beam and fits any Leclerc floor loom and most other brands. The tension is adjustable, and it gives uniform tension on all warp ends as they are wound from the spool rack to the loom. Two open 12 threads per inch combs allow easy threading and help guide threads into the proper section.
The tension box can also be used with an optional counter when filling bobbins, to give the number of yards on bobbins. 6160-1000
