Among the various cross-sectional shapes of the AccuRide slide rails, this model is a medium load type with a height of 35.3 mm and a thickness of 19.1 mm, featuring a three-member (full travel) design. The difference between this model and model 307 is only in the side space; the side space of this model is 9.5 mm, while that of model 307 is 16.5 mm. This side space means that model 305 is much easier to handle when mounting units on various racks. For more details, please refer to the model 305 catalog (PDF). The total length of the slide rails is standardized from 304.8 mm (12 inches) to 711.2 mm (28 inches). This slide rail features a front disconnect lock type, so when pulling out the drawer to its full travel, the lock engages due to the disconnect spring. To release the lock from the engaged position or when removing the drawer member, it must be done manually.
