Supermicro Tower-to-Rack Rail Kit for SC743 / SC745
4U–5U rack conversionSC743 · SC745Rails 26"–35.9"Ball-bearing
The Supermicro CSE-PT26L-B is a tower-to-rack conversion kit for Supermicro SC743 and SC745 tower chassis: ball-bearing rails plus chassis handles that turn the tower into a 4U rack-mounted server in a standard 4-post rack.
Supermicro designs the kit for chassis 16.7 inches wide and 26 inches deep, with an outer rail that extends from 26 to 35.9 inches to suit common rack depths. It is listed as the optional rack-mount rail for systems built on the SC743, such as the SuperServer 7047A series, so a server bought as a tower can move into the rack later without changing the chassis.
Before you order: Supermicro lists the CSE-743 and CSE-745 chassis for this kit. To convert, the top cover and the four feet of the tower are removed. A 4-post rack is required; 2-post racks and wall cabinets are not suitable.
What's in the Box
- Two rail assemblies (inner chassis rail and outer rack rail)
- Left and right rail brackets
- Chassis handles for rack use
- Mounting screws
What It Means in Practice
- Turns an SC743/SC745 tower server into a 4U rack server on sliding rails.
- Ball-bearing rails let you pull the server out for service.
- The outer rails extend from 26 to 35.9 inches to fit typical 4-post rack depths.
- Plan 4U of rack space plus room for the server to slide forward.
What Will Not Work
- 2-post racks or wall cabinets.
- Racks with post spacing outside the 26–35.9 inch rail range.
- Other Supermicro tower families (e.g. SC731, SC732, SC747) unless Supermicro lists them — ask us first.
- Non-Supermicro tower cases.

Singular Expert Insight · Buyer's Guide
Tower servers often start under a desk and move into a rack once the business grows. With the right rail kit the move takes minutes and keeps the same chassis. Complete the rack with items from our
rack accessories.
✓ Buy it if you want to move a Supermicro SC743 or SC745 tower server into a 4-post rack.
✕ Skip it if you have a 2-post rack or a different chassis family.
→ Also consider a heavy-duty fixed shelf if your rack cannot take sliding rails.
Send us your server or chassis model and the depth of your rack, and we will check compatibility before you order.
