Heavy Duty Folding Legset. This is the recommended folding base for any table. Yes they are expensive, but you definately get what you pay for on this. Constructed of Heavy Duty welded tubular steel, with a black powdercoat finish.
 
When properly tightened, these legs are as solid as a wooden pedestal base!
 
Highly recommended for (heavy) 9 foot table option, and racetrack tables.
