A slide rail assembly includes a first rail, a second rail, a stop, and a working member. The second rail can be displaced with respect to the first rail. The stop is disposed on the first rail. The working member is movably mounted on the second rail. When reaching a predetermined position after being displaced with respect to the first rail from an extended position in a retracting direction, the second rail is blocked by the stop via the working member and is thus prevented from being displaced from the predetermined position in an opening direction. The slide rail assembly has a shorter length when the second rail is at the predetermined position than when the second rail is at the extended position.

A slide rail assembly includes a first rail, a second rail, a third rail, a synchronization device and a contact feature. The second rail is displaceable relative to the first rail. The third rail is displaceable relative to the second rail. The synchronization device is arranged on one of the second rail and the third rail. The contact feature is arranged on the other of the second rail and the third rail. The third rail and the second rail can synchronously displace relative to the first rail through the collaboration between the synchronization device and the contact feature.

A drawer slide having first and second rails interconnected by a center rail. The center rail includes a spool configured to provide half-speed travel of the center rail relative to the travel of the first rail. The drawer slide is configured for use with a drawer assembly having a drawer and a chassis. The drawer assembly further includes a radius limiter secured to the center rail. The radius limiter travels at half-speed relative to the drawer. The radius limiter also automatically rotates relative to the travel of the drawer. The chassis includes sides including threaded backing plates, and mounting brackets. The mounting brackets include tri-lobed holes for receipt of a reciprocally shaped washer and a fastener for mounting the brackets to the chassis sides.
