The new ARCLINE products from Pocket Form Isolator are an innovative, new solution to your column isolation needs. Radial design provides exceptional load bearing strength using 40% less plastic than traditional PFI’s.


ARCLINE products are especially beneficial in monolithic, jointless, and extended joint slab pours where control saw joint spacing burdens are a major consideration.

ARCLINE products can be utilized in every structural column form scenario: interior isolation, along-the-wall, interior corner, and exterior corner.
