pangea Audio Vulcan X Four Shelf Audio Rack Media Stand, and Components Cabinet 

• Extremely Strong Design – Pangea Audio's 32"-tall four-shelf Vulcan X-Brace Audio Rack provides rock solid support for hi-fi and home theater gear. Its design features steel support tubes and steel X-braces connected by threaded rods for a super strong and ultra-rigid rack you can assemble in minutes without dipping into your toolbox.
• Easily Expandable - Thanks to the modular design, you can conveniently add or remove shelves for as many as six shelves in all as your equipment needs change. One user said that adding shelves was as easy as changing a light bulb. Just flip the Vulcan X-Brace upside down to add shelves from the bottom.
• Extra-Thick Generously-Sized Shelves - The X-Brace rack holds a system’s worth of electronic components, boasting four generously sized 23.75” wide, 18” deep, and extra-thick 19mm-thick (.75”) shelves. The dense MDF shelves are wrapped in a special vinyl material in satin black, rosenut, or carbon fiber finish
• Open-Air Design is Best for Your Gear – The open-air design is best for your electronics. The design maximizes component ventilation and makes it easy to install or remove gear. The four steel support tubes feature scratch-resistant and resonance-resistant black sand powder coat paint.
• Innovative Cone Point Feet and Spike Design – X-Brace features innovatively designed cone point feet and spikes. The steel floor spikes go all the way through the cones and into the bottom shelf tubes for greater strength and better energy transfer from the rack into the floor.

Do not exceed 90 lbs. per shelf or 360 lbs. total. Ensure the rack is properly installed using the cone point feet and spike design for stability and safety.
