Provide the total equipment weight, including the chassis and installed components, so we can confirm suitability for your configuration and operating conditions.
Product Details

Match the rail to your chassis
Share the chassis depth, width, U height and mounting drawing. We review the rail configuration, bracket adjustment and mounting interfaces before recommending the setup.

Ball-bearing sliding
MS-TLS-120 runs on a ball-bearing slide. The number of sections and the travel are confirmed on the drawing for your configuration.

Tool-less installation
The rails install without tools. Rack-side and chassis-side mounting interfaces are reviewed against your drawing.

Custom length and mounting-hole positions
Rail length and mounting-hole positions can be customized. Send your chassis drawing and required dimensions so we can confirm the configuration through drawing review and sample validation.
Load capacity
The specified capacity is 120 kg per pair. Provide the total equipment weight, including the chassis and installed components, so we can confirm suitability for your configuration and operating conditions.
What to send for a recommendation
- Chassis length (depth), width and U height
- Total equipment weight, including the chassis
- Mounting-hole drawing, 3D CAD or photos, if available
- Sample quantity and expected order quantity

FAQ
Is this a friction rail?
No. MS-TLS-120 uses a ball-bearing sliding mechanism.
Which racks and chassis sizes does it support?
Standard 19-inch racks with 1U to 4U chassis, 430–435 mm wide. Chassis depth and mounting interfaces are reviewed during selection.
What is the load capacity?
The specified capacity is 120 kg per pair. Tell us the total equipment weight, including the chassis and installed components, and we confirm suitability for your configuration.
Can the length and mounting-hole positions be customized?
Yes. Both can be customized, with final dimensions confirmed by drawing and sample validation.
What should I send for a recommendation?
Chassis depth, width and U height; total equipment weight; a mounting drawing, CAD file or clear photos; sample quantity and expected order quantity.
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.

Read the caseFrom 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.
