Lay-in wireways for a space divider system

A vertical spine for placement in a modular panel, space-dividing system, comprising:

• the spine, having side edges, a top and bottom, and a front and back, the side edges being spaced apart and extending vertically between the top and bottom and extending in a front to back direction between the front and back;
• attachment means attached to each side edge for releasably attaching the spine between a pair of modular panels in positions against each side edge of the spine, respectively;
• the spine being shaped and arranged such that a front and back open channel are defined as extending vertically substantially between the top and bottom of the spine, over the front and back of the spine, respectively;
• and,
• a front and back resilient strip mounted in the front and back channels, respectively, such that the resilient strips and channels define substantially enclosed wireways, which wireways extend vertically for encompassing wires extending in the vertical direction;
• each resilient strip comprising an elongated tube with a longitudinal slit forming an openable seam, and having normally closed positions over the channels, the resilient strips retaining said wires and being deflectable to permit forcible insertion and removal of the wires into and out of the respective wireway.
