An anti-tip assembly for use with a shelving system movable along a track. The track includes a first flange overhanging a first longitudinally extending channel and a second flange overhanging a second longitudinally extending channel. The anti-tip assembly includes an open ended channel, and a first bracket having a first flange extending into a first open end of the open ended channel, and a second flange extending into the first channel of the track. The anti-tip assembly further includes a second bracket having a first flange extending into a second open end of the open ended channel, and a second flange extending into the second channel of the track. The first and second brackets are slidable inside the open ended channel and coupled together with a maximum spacing therebetween. A biasing member biases the first and second brackets outwardly away from one another within the maximum spacing.
