20-Inch Rackmount Slider Rail

The Athena Power RM-Slider 20 is a full-travel, three-member slide rail designed for 2U to 4U industrial PC rackmount cases. It fits server chassis that require a 20-inch mounting depth. Built from 15-gauge cold-rolled steel, it supports heavier equipment than typical 10 to 12-gauge alternatives. This new accessory suits integrators building or servicing rackmount servers in standard cabinets.

Silent Ball-Bearing Operation

Ball bearings on the intermediate member deliver precise linear motion with smooth, silent travel during normal extension and retraction. The heavy-duty steel construction minimises vibration and noise when sliding a loaded chassis in or out of the rack. A lock-open mechanism secures the chassis in the extended position for safe, hands-free access to internal components. No power draw or thermal output is generated by this passive mechanical component.

145-lb Sustained Load Capacity

The slider carries a load rating of up to 145 lbs, maintaining structural integrity under continuous fully extended load rather than only during brief insertion. The 15-gauge steel inner, intermediate, and outer members resist permanent deflection over long service periods. Additional tapped screw holes on the outer member allow direct L-bracket mounting without separate nuts, reducing installation time for permanent deployments. First listed by the manufacturer in 2007.

Questions about this item

How do I install the RM-Slider 20 rails and which step is most often missed?

Mount the outer members to the rack using the extra tapped screw holes on the 1.79" wide rail; the step most people skip is locking the intermediate member in the open position before sliding the chassis in.

What maintenance or replacement will the RM-Slider 20 need over time?

The ball-bearing intermediate members on the 15 gauge cold-rolled steel rails may require periodic lubrication; if travel becomes rough or the lock-open feature fails, replace the full three-member assembly.

What limit appears first when the RM-Slider 20 is used continuously at full extension?

The 145 lbs load rating is the first limit reached under sustained use; exceeding it can deform the .5" thick steel members and compromise the lock-open mechanism.
