Coral Frag Racks

Flat plates with 6, 12, 24, or 40 holes that hold coral frag plugs upright by their stems. Cut for the 9.525mm (3/8 inch) stem. Hang one on the rim or stand it on the tank floor.

A frag rack is a flat plate with holes in it. Each hole takes the stem of a coral frag plug, so the plug stands up on the plate. There is no standard size for a frag plug stem. Brands publish 9.0mm, 9.525mm (3/8 inch), 10.0mm, and 11.113mm (7/16 inch), and one brand sells two of those sizes in its own store. Our holes are cut at 10.125mm, for the 9.525mm stem, so measure your own plugs first. Pick the rim hook version to hang it on the tank wall, or the standoff version to stand it on the tank floor.
