OIC 3-1/2″ Prong Fasteners Set

Prong fasteners fasten papers and documents easily and securely. Complete two-piece fastener includes prong base and compressor. They are ideal for use in file folders that need to be modified or added to frequently. Locking compressors slide over base prongs to keep a stack of up to 3-1/2″ papers tightly compressed to save valuable filing and storage space. Both bases and compressors are made of brightly finished, corrosion-resistant steel. 2-3/4″ base fits in regular, two-hole punched paper.
