Magnetic holders are high strength magnetic inserts that firmly hold the hole former to the form core. This design eliminates the need to use wire to tie hole former's to the cage or to screw or bolt the hole former to the form. Also allows easy positioning and removal and takes away the risk of moving or floating hole former's.
