High quality drum lug. Order the mounting screws separately. These lugs also require the rubber gaskets to align properly on most drums, now included. Photo may show double ended, but item will ship as a SINGLE ended lug. There is no bass drum specific version of this lug available to us. But customers report making this this function as a BD lug by adding custom made spacers to raise it for better alignment with BD hoops. NOTE: Mounting screws are NOT included with our lugs, since we offer many lengths for different shell thicknesses. Very sorry, the gaskets for this lugs are not available as a separate item, only along with the lug.
