This is a complete Dell ReadyRails 1U Sliding Rack Mount Rail Kit (RailType A1), manufactured by Qualslide®.

These are professional-grade, 3-section sliding rails designed to allow yourserver to smoothly extend completely out of the rack for easy maintenancewithout unmounting. We have 18 complete pairs (Left and Right) availablein stock, perfectly sorted and ready to ship, butIn this lot, you are offerding on 6 pairs of rails (12 pieces = 6 Left & 6 Right). If you want more or less,please let us know and we can list more.

• How it Works: It is a 3-section sliding rail kit designed for toolless installation into standard 4-post square-hole server racks. It allows a 1U server to slide completely out of the rack enclosure for servicing without being unmounted.
• Component Part Numbers Pictured: * DP/N R137J / 0R137J: The main 1U outer chassis rail assembly.
• DP/N R163J & R162J: The specific right and left inner slide members that mount directly to the side of the server.
• DP/N P261J & N921J: Intermediate slide structure component part numbers.
• Exact System Compatibility: Engineered specifically for the Dell PowerEdge R610 1U rack server. It will not properly fit other generations (like the R620 or R630) because Dell changes the chassis mounting pin configurations between generations.

Component Part Numbers & Technical Specs:

Because Dell uses modular engineering, multiple individual stamp numbersmake up this complete kit assembly. You will find these exact markings on yourunits:

·Outer Rail Kit DP/N: R137J / 0R137J

·Inner Rail Component Stamped P/Ns: R163J(Right), R162J (Left), N944J, N921J

·Rail Type: A1 (1U Form Factor)

·Mounting Style: Toolless installation forstandard square-hole 4-post server racks. No additional hardware or toolsrequired to secure them into the rack cabinet.

Condition

·Surplus / Excellent Working Condition:Hardware mechanisms slide smoothly, and the spring-loaded quick-release raillatches lock properly. May show minor scuffs, cosmetic surface wear, or dustfrom a warehouse environment, but they are fully functional as intended.

1. Dimensions (Closed vs. Completely Open)

·ClosedLength (Minimum Depth):28.1 inches (714 mm)

oThis is the profile depth of the rail itselfwhen fully retracted inside a cabinet. The rails areadjustable to fit standard 4-post server racks with a front-to-back post-spandepth ranging between 24.8 inches to 34.1 inches (631 mm to 868 mm).

·Completely Open Length (Full Extension):Approximately 54.5 inches (1,384 mm)

oBecause these are a 3-section full-extensionsliding design, the middle and inner segments slide all the way out,effectively doubling the length of the rail. Thisprovides complete clearance so the server can be entirely serviced outside therack footprint.

2. Maximum Weight Capacity

·Load Rating: Upto 100 kg (220 lbs)

oEnterprise 1U sliding rails are heavilyengineered out of structural steel to withstand maximum vertical stress when afully configured server (including heavy dual power supplies, internal drives,and full expansion cards) is fully extended and hanging out in mid-air.

3. Rail Mechanism Description (Dry Slide)

·Slide Mechanism:Friction-based "Dry Slide" (Non-Ball Bearing)

oWhy it matters for buyers: Unlikeconsumer electronics drawers or older server rails that rely on greased, loosesteel ball bearings that can gum up with dust or lose bearings over time, Delldesigned these with precise, heavy-duty inner metal tracks engineered for highdurability. They glide cleanly without grease, minimizingdust buildup in data center hot-aisles.

·Material & Construction: Heavy-gaugeelectro-galvanized stainless steel.

·Key Features Built-In:

oToolless Release Latches: Features theiconic blue spring-loaded tabs on the front and rear mounting heads for instantsnap-in locking to square-hole server cabinets.

oCMA Support: Therear rail ends feature integrated mounting pins specifically shaped to acceptstandard toolless Dell Cable Management Arms (CMA).
