Abstract: A movable divider wall (28) for a drawer (10) includes a cam (32) secured to each opposite end, which cam is relatively compressible across a first direction and only slightly compressible across other directions. Channels (20, 22) are secured to the internal surfaces of opposing drawer panels and each presents a longitudinal recess (24) facing toward the other which are so dimensioned as to receive a cam (32). With the cam relatively compressible direction extending transversely of the recess (24) the cam (32) and divider wall (28) may be adjustably positioned within the drawer. Rotating the divider wall to a position where the cam slightly compressible direction is transverse to the channel recesses locks the cams and divider wall relative to the drawer.
