As of 7/12/201110 left ! get them while you can! Quality drum lug with center notch cut out to fit over center "bead" on a metal snar shell. Fits over bead on our black/ brass shells , but you'd need to buy the UNdrilled version and drill shell to match. Order the mounting screws separately. NOTE: Mounting screws are NOT included with our lugs, since we offer many lengths for different shell thicknesses. Parts noted Slingerland style mean that they look a bit like the Slingerland parts, the hole spacing fit could vary. There are no standard there. If you are trying to retrofit a Slingerland drum, make sure to measure your holes to compare for a fit.
