Schacht Raddle for the Arras, Wolf Pup, Baby Wolf, Might Wolf and Standard Loom.
Raddles help keep a warp spread evenly as it is wound onto the warp beam.

Schacht raddles are very flexible. They have built-in clamps and can be placed on the back beam or on the beater.  Metal pins have 1" spacing but extra holes are placed every half inch and you receive extra pins so you can make the spacing closer.  

All raddles come with clamp blocks that fit the Standard Floor Looms and many other brands. 

Wolf Pup, Baby Wolf, and Mighty Wolf Raddles also include U-brackets that sit on the rear oval beam. These universal brackets fit all Wolf looms.
