Symposium's new Precision Coupler replaces our former Large Coupler to provide superior performance and convenience.
Made of top-grade 7075 aircraft aluminum and precision machined to scintillating surface finishes, Precision Couplers are used to form an efficient mechanical connection to the components placed upon Symposium Platforms and Isis Rack levels, for effective damping of internal equipment resonances - an essential requirement for best results with vibration control devices. The high mechanical transmission efficiency of the aluminum alloy also provides an excellent transmission path for the evacuation of mechanical energy out of components and into a mechanical ground, where it can be absorbed and/or converted to heat energy.
Each Precision Coupler features nearly perfectly parallel top and bottom surfaces, and one side has a threaded 1/4-20 hole for attachment to many existing foot posts or for screwing two Precision Couplers together to form one high coupler to clear very high feet. Each Coupler is 0.8125 inches high (13/16" or 2.06 cm) and 1.875" (4.76 cm) in diameter.
