a generally cylindrical cage having a wall portion having an outer diameter less than a diameter of a drum head, a window extending from an outer face through to an inner face thereof, an axial bore therethrough dimensioned to admit a drum shell, the bore having a diameter larger than a diameter of the drum shell to be placed therein, and a spacer hole through the wall portion extending from the outer face through to the inner face;

a plurality of posts affixed to and extending outwardly from the cage outer face in circumferentially spaced relation therearound, the posts each having an aperture extending from a top end thereof, the apertures substantially parallel to a cylindrical axis of the cage and for receiving fasteners thereinto for affixing a drum head thereto;

a spacer having an insertion portion dimensioned for insertion into a hole in the drum shell and a head portion larger than the drum shell hole, the head portion having an axial bore therein extending from an outer face thereof; and

a pin having an insertion portion dimensioned for insertion through the cage spacer hole and into the spacer axial bore, the pin and the spacer thereby retaining the drum shell in spaced relation from the cage, a space therebetween determined by an axial height of the spacer head portion.
