Quadraspire parts and accessories are the columns, feet and bronze fittings that hold a Quadraspire rack together and set it on the floor, sold separately so a rack you already own can grow or change. On a Quadraspire rack the column length sets the spacing between shelves, so making room for a taller component means a new set of columns, not a new rack. Quadraspire makes its columns from solid aluminum rather than steel tube, which can resonate.
The SV Columns 32mm fit Q4 EVO, SVT, SVTL, SV2T and SV3T racks, in black or silver, in heights from 100mm to 382mm, along with the SV75 feet and top caps set. The X-Reference takes thicker 44mm columns in black, and the Signature columns are the same part in natural aluminum. The SV Bronze 30 Upgrade puts solid bronze under the top shelf of a Q4 EVO or SVT rack, and comes standard on every level of an X-Reference. The SV Flat Feet swap the spike for a flat face with a rubber pad, so the rack sits level without marking a hard floor. Starting from nothing? Build your own rack or pick a ready-made one.
