The EFA04 78 002 tray has been designed primarily for breadboarding of fiber optic layouts. Each of the three segments can be cut away from the others, if desired. Each segment has a central hole which is compatible with the EFA04 53 ASSY Stacking Post and the EFA04 27 ASSY Standoff. The peg-board holes are compatible with the rivets used for mounting several of the organizer parts. The hole is beveled on the bottom side of the tray to accommodate the rivet heads. The tray is made of flame-resistant plastic, and meets UL94 V0 standards.
