Massive weight load handling. Reconfigurable 8-way upright beams. Precision leveling base and shelf points. Quick, easy setup and relocation. 19-layer SIGNATURE shelf platform option. Advanced multi-stage decoupling. Unmatched frame and shelf rigidity. 100% virgin billet aluminum "60-63" T6 frame. Completely future proof reconfiguring. Gemstone encrusted stainless steel badge. Custom design services at no charge. Matching side and front panels. Specially engineered unhindered airflow. Zirconia Framework Colors: Silver, Polished, Black or RAL Custom Colors. Our uniquely designed shelf supports with decouples use patented sliding cam locks that allow you to raise, lower, add or remove shelf platforms to your exact desired height without welded joints, pegs, screws or bolts. This unique feature gives you new options to integrate turntables, top-load CD players and other small & tall equipment components. Patented 8-way upright column posts allow you attach other Zirconia designs into large entertainment centers, credenzas or cascading racking. This extreme engineered 1 & 5/8" (40mm) upright post uses the eight slotted channels to slide, couple or branch off of. Simply integrate other racks at any angle to wrap around 90-degree corners, expand 180-degrees sideways or at a 45-degree “wrap around” with infinite height adjustment. Virtually any design can be accomplished to your "vision". Standard Composite or Signature Series shelf platforms compliment your flexible Zirconia Series framework. The standard shelf highlights the advantages of our superior frame... while the Signature platforms address sound fidelity and the shelf enviroment.Signature platforms are the industries absolute reference providing true anti-vibration, advanced interference & induction shields, ESD protection, magnetic shielding and heat transference blocking while capable of holding massive weight loads.(Crystal & Diamond designs utilize more locking cams for even greater weight limitations.) Our designs provide the perfect place for your equipment to operate as it was designed to, without the damaging effects of nearby equipment and vibrations from loud volume conditions. The value of our Zirconia line is ongoing; you will never need to repurchase other fixed shelf racking systems in the future. You can completely conform to your current setup or rearrange it with any type of future need. Quintessential design properties permit modular attachment at 45, 90, 135 or 180 degrees to wrap around corners... or create large credenzas and entertainment centers. Add on to existing systems anytime to accommodate for new equipment additions. Beam adjustments are easily accessible and are perfect for for switching out equipment or leveling platforms at every point. If you desire the best with only the largest and most refined... please also view our ULTRA-high-end Crystal and Diamond designs. Large Zirconia structures are quickly assembled without loose parts, pins or screws. Simply place supports bars into upright channels and turn cams. Height adjustment and expansion takes only seconds without any of the limitations caused by welded or screwed frames. Standard smooth bottom leveling feet concede to flooring inconsistencies to precisely level over carpet tack strips, rugs, tile transitions or changes in ground coverings. The standard adjustable feet sink into carpet giving a flush, hidden foot. Leveling occurs at each foot post and also at each shelf support for ideal flexibility. Basic leveling feet can be upgraded with patented carpet sliders. Sliders easily move heavy loads on pile carpeting without the need for casters. This option allows more usable space than casters, without taking up vertical real estate. Gold, Silver, blackened chrome or solid black spikes firmly couple framework to sub-floors & slabs.  Since Audiav designs are "platform loaded" the fact that spikes couple takes the entire framework out of the vibration equation. Precision machined spikes are fabricated from solid brass and thick plated for durability. Two piece tip design is truly ideal for precise level adjustments when used with lighter load and small weight equipment. Spikes are designed to be screwed in completely without adjustment. Standard adjustable feet or sliders are recommended for heavily loaded racks. Swivel locking casters prevent rolling and spin rotation with a unique dual lock switch. Basic locking casters are recommended for applications where overall height is a concern. Flooring sliders are ideal for most applications requiring low height, long adjustability heights with heavy racking or equipment.
