Thickness of "4mm"(471 pieces), "20mm"(112 pieces), and "40mm"(57 pieces) ceramic glass spacers has been measured with 0.4um precision. According to the measurements we have full amount of the spacers to build the E614 detector with better than 0.4um precision. A reserve consist of about 20-30% of all types of spacers. -- Vladimir Selivanov Russian Research Centre "Kurchatov Institute", Moscow, Russia | e-mail: in Moscow | at TRIUMF(Vancouver,Canada) | | svi@slv.kiae.su | selivanov@triumf.ca | | svi@chen.net.kiae.su | | -----------------------------------------------------------------
