Steel Hole-Formers are an extremely durable hole-forming option. We have two different styles – zero taper “rings” and tapered “pans” – that can be made in a variety of different sizes, shapes, and structures.
At Blackthorn, we make our steel hole-formers are made heavy duty, built to last, and with precast in mind. They are custom made to your specifications.
