The HC Companies Dillen T1204 True Insert - 48-Cell Black Bedding Plant Insert - True Size

Dillen T1204 True Insert — 48-Cell Nursery Insert, True-Size

Standard 1020 flats are not universal, and forcing one into a True-size bench system wastes space and breaks handling consistency. The HC Companies Dillen T1204 True Insert is built specifically for True-size flats, holding 48 cells in a 12x4 grid across a 20in L x 10in W x 2.5in H footprint that is not interchangeable with the standard 1020 line.

Vacuum-formed from durable black plastic with precision-burned drainage holes and die-cut trims, the T1204 gives growers already standardized on True-size systems a reliable drop-in insert for germination, propagation, and liner production.

Key Features & Benefits

• True-size footprint — 20in L x 10in W x 2.5in H fits True-size flats precisely and is not interchangeable with standard 1020 flats.
• 48-cell 12x4 layout — uniform grid supports efficient bench utilization and accurate stand counts.
• Vacuum-formed construction — consistent wall thickness and cell geometry reduce transplant variability batch to batch.
• Burned-in drainage holes — precisely placed openings support consistent drainage and air pruning, reducing waterlogging risk and encouraging fibrous root development.
• 13.5oz total liquid volume — cell depth and volume retain moisture between waterings while maintaining drainage performance.

Frequently Asked Questions

What is the difference between a True Insert and a Standard Insert?

True Inserts use a 20in x 10in footprint for True-size flats, while Standard Inserts use the larger 21in x 10.5in footprint for standard 1020 flats. The two series are not interchangeable.

How many cells does the T1204 hold?

This model holds 48 cells arranged in a 12x4 pattern, for a total liquid volume of 13.5oz. Cell count is the main difference across the True Insert series.

Can I use the T1204 in a standard 1020 flat?

No, the True-size 20in x 10in footprint does not fit standard 1020 flats. Use a Dillen D-series Standard Insert for standard 1020 flat systems instead.

Is the T1204 compatible with automated equipment?

Yes, consistent exterior dimensions allow reliable nesting and de-nesting on automated transplant and seeding lines configured for True-size inserts. That consistency helps avoid jams during high-speed automated production runs.
