"Duo Tang Strips" will hold up to 50 sheets, and can be attached to most of the standard size folders.

A tang strip is just the spine portion of a tang folder with the tang and reinforcement eyelets installed.  The piece is then stapled or glued into a folder.  Bulk packed and ready for your installation.

Complete two-piece fastener includes prong base and compressor. Ideal for use in file folders that need to be modified or added to frequently. Locking compressors slide over base prongs to keep papers tightly compressed to save valuable filing and storage space. Both bases and compressors are made of brightly finished, corrosion-resistant steel.
