Abstract

A modular binder ring unit (16) used in a ring binder (10) comprises a plurality of modules including a binder ring module (18). The modules are spaced along the length of the unit. A plurality of spacer modules (22, 24, 30) attach to the ring modules. The spacer modules are available in different lengths, and a combination of different length modules are usable together with the ring modules to form a binder ring unit of a desired length. The spacer modules space the ring modules an appropriate distance apart for the binder rings to be at locations corresponding to holes (H) in a sheet of paper (S) stored in the binder. End caps (26) are removably attachable at each end of said unit for locking the ring modules and spacer modules in place. Each module element is an elongate module having a recess (R) formed in one end and an extension (E) at the opposite end for securing one module to an adjacent module. Each extension is sized to fit in the recess formed in the adjacent module to which the one module is secured.
