Technical Specifications
Product Summary
MetrixSlide MS-FMR-2U-100 friction server rails are designed for standard 19-inch racks and 1U to 4U server chassis 436–439 mm wide. They install without tools, carry 100 kg, and are supplied with custom rail lengths and mounting-hole positions. In the factory static-load test, one pair of rails held a 100 kg total load, including the chassis, at full extension for 24 hours with no detachment or jamming and with function retained. The tested rails were 880 mm long and the chassis was 438 mm wide. The result applies to that configuration; a change to the rail length or the mounting details is reviewed for the intended load.
Product Details
Built around your chassis dimensions
Start with your chassis depth, width, height and total equipment weight. MetrixSlide selects the rail length and bracket adjustment configuration, then matches the mounting-hole positions to your drawing.
Tool-less front-end mounting
The rails install without tools. Rack-side and chassis-side interface details are reviewed against your chassis drawing.
Rear bracket and rail structure
The rear mounting assembly and the rail-to-bracket connection, photographed on the actual product. The mounting configuration is confirmed during drawing review.
Custom length and hole positions
Once the base rail configuration is selected, we can customize the rail length and mounting-hole positions to suit your chassis. The proposed dimensions and mounting details are reviewed in the drawing stage, followed by sample validation before production.
If a request changes the rail structure or mounting architecture, we assess it as a separate engineering requirement.

Key Features
100 kg load capacity
One pair of rails held a 100 kg total load, including the chassis, at full extension for 24 hours in the factory static-load test.
For 1U to 4U chassis 436–439 mm wide
Built for 1U to 4U server chassis in standard 19-inch racks. Chassis depth and mounting details are checked against your drawing.
Tool-less installation
The rails install without tools. The rack-side and chassis-side interfaces are confirmed during drawing review.
Friction sliding mechanism
A friction slide rather than a ball-bearing slide.
Custom length and hole positions
Once the base configuration is selected, rail length and mounting-hole positions are matched to your chassis and confirmed by drawing review and sample validation.

FAQ
Is this a ball-bearing rail?
No. This model uses a friction sliding mechanism.
What is the load capacity, and how was it tested?
100 kg. In the factory static-load test, one pair of rails held a 100 kg total load, including the chassis, at full extension for 24 hours. The tested rails were 880 mm long with a 438 mm wide chassis. This is an in-house test, not a third-party certification.
Which chassis is this model intended for?
1U to 4U server chassis 436–439 mm wide in standard 19-inch racks. Share the chassis depth and mounting details so we can confirm the rail configuration.
Can the rail length and mounting holes be customized?
Yes. Both can be adapted to the application, with final dimensions confirmed through drawing review.
Can you supply a different rail length?
Yes. We review the required length, mounting details and equipment weight together, then confirm the drawing and sample configuration.
What are the MOQ and sample lead time?
Sample quantity and order quantity are agreed with the project. For a customized version, sample pairs are typically ready 15 to 20 days after drawing approval. Samples are quoted with the project.
Check the fit for your chassis
Send the chassis depth, width and U height, the total equipment weight including the chassis, and a mounting drawing, CAD file or clear photos. We reply with a rail recommendation within 24 hours.

From first conversation to installed rails in eight steps
The same process for a standard kit or a fully custom rail: you send the inputs, we return drawings, samples prove the fit, then we build the full order and support installation.
- 01
Discuss your requirements
Application, server type, quantities and timeline. An engineer joins the first conversation.
- 02
Send chassis & rack parameters
Chassis drawing or model, width and depth, mounting features, rack post distance and load.
- 03
We deliver a 2D / 3D model
A rail matching proposal within 24 hours, then 2D drawings or a 3D model for your review.
- 04
You place a sample order
Typically 10–100 pairs, enough to test fit and function on real chassis and racks.
- 05
We tool up and produce samples
Custom dies are made in-house, samples are built, inspected and shipped to you.
- 06
You validate and place the full order
Physical fit and load checks on your side, then the design is frozen and the production order confirmed.
- 07
Volume production and delivery
Full-quantity production under ISO 9001 controls, export packing and shipment by sea or air.
- 08
Installation with our support
Installation guidance and after-sales support from the factory for every kit delivered.
