The Lead Line Clutches is a pair of metal retractable clamps invented by Professor Dweeb.
While being moved by Elizabeth on the High Wire Bike, Professor Dweeb unleashed his Lead Line Clutches and grabbed hold of Slimer. However, Slimer was preoccupied with wallpaper and forced his way out of the device. Dweeb later tried a variant of it on Slimer while stuck in the "Haunted Spaceship" movie. It missed and clamped on the Squid Monster instead. He easily brushed it off and disposed of Dweeb and Elizabeth.
