3U 2Post-to-4Post Conversion Kit

This four-piece bracket kit converts a two-post relay rack into a four-post enclosure so 3U servers from Dell, HP, IBM and similar brands can be mounted securely. Each bracket spans three rack units and fits standard 19-inch and 23-inch EIA cabinets with three-inch or six-inch uprights. All mounting hardware is included for a straightforward retrofit.

Weight and Width Limits

Every rack unit supports up to 50 lbs, so the total load across the 3U height must stay within that per-unit rating. The server chassis, including its own mounting rails, cannot exceed 17.72 inches in width or it will not fit between the uprights. These two constraints define whether a given appliance can be installed safely.

3U Height Compatibility

The brackets are built specifically for 3U-high equipment; shorter or taller servers will not align with the mounting holes. Buyers needing to convert space for 1U, 2U or 4U devices should select a different kit height.

Questions about this item

How do I decide between the 3U and other height kits?

Choose this 3U kit when your server occupies three rack units; each bracket set converts exactly 3U of vertical space.

What does the 50 lb per rack unit rating mean for my 3U server?

The brackets are rated for 50 lbs in each individual rack unit, so a 3U chassis is supported across all three units at that same per-unit capacity.

Will these brackets fit my 19-inch or 23-inch EIA rack with 3-inch uprights?

Yes, they mount in standard EIA 19" and 23" racks and are designed for 3-inch wide uprights; the kit includes all hardware for installation.
