Some beautiful reef rocks have a lot of spots to attach coral frags, but the holes are just too small to fit the standard frag plugs. These will securely hold your existing frag plug on a flat surface or bury in sand!
Diameter, these are looser fits, not too snug (glue if needed):
Normal: 10.5mm for 3/8in base plugs
Large: 11.75mm for 7/16in base plugs
DOES NOT INCLUDE FRAG PLUGS.
