a device for a slidable assembly may include a support channel , defined by first , second , and third support sides and including a primary support bearing and a tertiary support bearing , and a slide channel , defined by first , second , and third slide sides and including a primary slide bearing and a tertiary slide bearing . in an assembled state , the slide channel may fit around the support channel such that the primary support bearing contacts the first slide side and the primary slide bearing contacts the first support side such that the first slide channel is configured to slide longitudinally with respect to the first support channel , and the tertiary support bearing contacts the first slide channel and the tertiary slide bearing contacts the first support channel to restrict lateral transition of the first slide channel with respect to the first support channel .
