Raddles help keep a warp spread evenly as it is wound onto the warp beam. Ours can be attached to either a back beam or the shuttle race of the beater. The raddles come with plated pins inserted every inch; if you prefer half-inch spacing, you can install extra pins (included) in every hole. Baby Wolf Raddles also include U-brackets that sit on the rear oval beam. These universal brackets fit all Wolf looms.
