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.

1. A slide arrangement, comprising: a) first and second rails including first and second structures, respectively;b) an I-shaped center rail including: i) a center portion having a longitudinal dimension that extends between opposite ends of the center portion;ii) transverse portions located at the ends of the center portion, the transverse portions being oriented transverse to the longitudinal dimension of the center portion to define the I-shape of the center rail;iii) the I-shape of the center rail defining first and second longitudinal constructions extending from a first end to a second end of the center rail, each of the first and second longitudinal constructions being sized to receive only one of the first and second structures of the first and second rails, respectively, each of the first and second structures of the first and second rails, respectively, being configured to slidably engage the first and second constructions of the center rail;iv) the first longitudinal construction of the center rail including a first longitudinal groove extending from the first end of the center rail to the second end, and the second longitudinal construction including a second longitudinal groove extending from the first end of the center rail to the second end; andc) a spool configured to contact at least one of the first and second rails when the first rail slides relative to the second rail, the spool having an axis of rotation parallel to a longitudinal dimension of the center portion of the I-shaped center rail. 2. The slide arrangement of claim 1, wherein the first structure of the first rail includes a first interlocking structure, and the second structure of the second rail includes a second interlocking structure, each of the first and second interlocking structures being configured to slidably engage the respective first and second grooves of the center rail. 3. The slide arrangement of claim 1, wherein the spool is positioned at the center rail. 4. The slide arrangement of claim 3, wherein the spool is positioned within a receiving structure formed in the center rail. 5. The slide arrangement of claim 4, wherein the spool has a snap-fit construction configured for receipt within the receiving structure of the center rail. 6. The slide arrangement of claim 5, wherein the spool includes a flexible outer ring configured to snap fit within the receiving structure of the center rail. 7. The slide arrangement of claim 6, wherein the flexible outer ring includes a plurality of ring sections circumferentially spaced apart from one another, the ring sections being configured to flex when the spool is snap fit into the receiving structure. 8. The slide arrangement of claim 4, wherein the receiving structure includes apertures formed in the center rail. 9. The slide arrangement of claim 8, wherein the apertures are formed within the first and second longitudinal constructions of the center rail. 10. The slide arrangement of claim 9, wherein the spool includes an o-ring circumferentially positioned about a spool axle. 11. The slide arrangement of claim 9, wherein the o-ring extends through the first and second apertures of the receiving structure to contact the first and second rails. 12. The slide arrangement of claim 11, wherein the o-ring extends through the apertures to contact the first and second interlocking structure of the first and second rails, respectively. 13. The slide arrangement of claim 1, wherein the spool is configured to permit the center rail to travel at half-speed relative to the travel speed of the first rail when the second rail is held stationary. 14. The slide arrangement of claim 1, further including a catch arrangement configured to pause sliding movement of the first rail when the first and center rails have reached a first extended position. 15. The slide arrangement of claim 14, wherein the catch arrangement includes a projection located at an end of each of the first and second rails, the projection being sized to cause an interference with the spool when the first and center rails reach the first extended position. 16. The slide arrangement of claim 1, further including a positive stop arrangement configured to prevent linear separation of the first and second rails from the center rail. 17. The slide arrangement of claim 16, wherein the positive stop arrangement includes a shoulder formed on each of the first and second rails, and stop ledges formed on the center rail, the shoulders being configured to contact the stop ledges of the center rail to prevent further longitudinal travel beyond a second extended position. 18. The slide arrangement of claim 17, wherein the shoulders are formed on first and second interlocking structures defined by the respective first and second structures of the first and second rails, and the stop ledges are formed within first and second longitudinal grooves defined by the respective first and second longitudinal constructions of the center rail. 19. The slide arrangement of claim 16, further including a catch arrangement configured to indicate when the rails have slid to an extended position relative to one another, wherein engagement of the catch arrangement occurs prior to engagement of the positive stop arrangement.
