The streamlined shape of the Rig Boom offers knot protection, reduces tangles and helps lay the hooklink out away from the lead. Streamliner Rig Booms have three prime functions. To mask and protect the knot, to act as a stiff boom to prevent tangles and to help lay the hooklink out away from the lead. Unlike other anti-tangle sleeves which tend to float up off the bottom at an angle, these are moulded in a heavy polymer which lays flat, minimumising the need for tungsten putty.
