Optical Ocean Modular tray set (strobe and housing not included). Includes tray and housing screw, handle, two connectors, one 10 arm, and one 6 arm with YS strobe connector. Both ends on the 6 strobe connector are a little loose. They twist side to side slightly but do not feel as if they will pull off. $60.00 More detail can be found at this link: http://opticaloceansales.com/trays-and-arms/tray-and-arm-packages/modular-tray-set-1.html
