Blackthorn’s Styrofoam Mounting Magnets enable quick and easy attachment of foam hole-formers to steel molds.

Simply push the magnet into the foam hole-former, place against your mold, and the foam hole-former will be securely held in place for the duration of the pour.

EASY and RELIABLE – no more tying in foam hole-formers with wire and no more floating foam hole-formers.

Foam Mounting Magnets work best with small to medium size holes. MAGNETIC STEP PIN ASSEMBLIES can be used to mount large foam hole-formers.
