T.O. Plastics Standard 1020 Insert #2401 - 24 Cell - 4x6 - Black - 100pc

Standard 1020 Insert for Seedling and Liner Production, #2401 24-Cell

A plug insert that does not match the flat tray dimensions underneath it can shift, gap, or crowd cells against the tray wall, and a mismatched cell count wastes bench space across a large production run. T.O. Plastics' Standard 1020 Insert line is sized to fit a standard 1020 flat tray exactly, using straight cell walls that maximize soil volume per cell while still de-nesting cleanly from the stack.

Each cell in this #2401 insert measures 2.19in x 3.00in x 2.25in D (12.50 cu in), arranged in a 24-cell, 4x6 layout that fills a standard 1020 flat tray edge to edge.

Key Features & Benefits

• Straight cell walls — maximizes usable soil volume per cell instead of narrowing toward the bottom like a tapered cell.
• Sized to a standard 1020 flat tray — fits without gaps or shifting across the tray footprint.
• Easy de-nesting — separates cleanly from the stack for faster filling on a production line.
• Black, 100pc per case — ships ready for commercial-scale seedling or liner production.

Who Should Use This Insert

This fits growers running standard 1020 flat trays who need a 24-cell, 4x6 layout sized for their seedling or liner production line, with straight walls maximizing root volume in each cell.

Frequently Asked Questions

Why do straight walls matter for a plug insert?

A tapered cell wall narrows toward the bottom, which reduces usable soil volume compared to a straight-walled cell with the same top opening. More usable soil volume generally supports stronger root development before the plant needs transplanting.

How do I know this insert fits my flat tray?

This insert is sized specifically to fit a standard 1020 flat tray without gaps or shifting. Confirm you are using a standard-depth 1020 flat tray rather than a shallow or deep variant, since insert and tray depths need to match.

What is the cell volume on the #2401 insert?

Each cell on the #2401 insert measures 2.19in x 3.00in x 2.25in D, giving 12.50 cubic inches of soil volume in a 24-cell, 4x6 layout. That volume determines how much room roots have before the plant is ready to size up or transplant.

Does the straight-wall design make de-nesting harder?

No, T.O. Plastics builds this insert to de-nest cleanly from the stack despite the straight walls, so growers do not trade off separation speed for soil volume. This keeps filling lines running at a consistent pace.
