Cast Aluminum Spring Core Adapter

The Quick Release Alternative to Core Cones

Progressive Machine Company's unique cast aluminum Spring Core Adapter offers a permanent, easy to use replacement for core cones or other core securing devices.

This patented product utilizes a special spring lock mechanism to secure the core against the tension direction. The adapter remains free to operate in the opposite direction and thus enables an operator to facilitate core removal. The unit is secured by a spring release hub that allows for quick positioning and release by simple finger tip pressure. Its flexibility of design provides for use in either off the top or bottom material flow.
