Waterbox aquarium lid planning
Built around your REEF LX 380.8.
Use Keepr's research-backed Waterbox REEF LX 380.8 profile as a measured starting point. Verify every estimated value and equipment opening on your own tank before approving production.
Some geometry is estimated or derived from related documentation and must be checked against the exact aquarium.

Evidence
What is documented
- Published outside footprint: 2448 × 750 mm (96.38 × 29.53 in).
- Pane construction: 19 mm front and sides with 15 mm euro-bracing.
- Some geometry is estimated or derived from related documentation and must be checked against the exact aquarium.
- Manufacturer-published rectangular outside dimensions and wall glass used as dimensional starting measurements; the manufacturer identifies continuous perimeter euro-bracing as a flush horizontal lid seat, so the editor nests the lid footprint inside the tank walls using the customer-measured clear opening. The clear opening and exact tank revision remain customer-verified.
- Waterbox publishes a 480 × 100 mm REEF LX overflow-lid footprint; placement is centered as a temporary lid datum inside the eurobraced seat.
- Catalog evidence reviewed 2026-07-24.
Design guidance
Plan the lid around this tank
- The builder may show a temporary factory-opening estimate. Replace its size and position with measurements from your tank.
- Confirm the brace layout, clear-opening width and front-to-back span, glass thickness, and clear lid seat before defining the lid footprint.
- Choose section seams so each printed frame stays practical to handle without crossing an overflow or light mount.
Process
From profile to production drawing
- Match the research to the exact tank and generation.
- Measure the lid seat and every equipment opening.
- Design the lid and review the live quote.
- Approve the production drawing before checkout.
Questions
Before you build
Do I still need to measure my Waterbox REEF LX 380.8?
Yes. Confirm the exact model and generation, measure your own tank and equipment, review every opening, and approve the production drawing before ordering.
What does “Reference profile” mean?
Some geometry is estimated or derived from related documentation and must be checked against the exact aquarium.
How is a Keepr custom lid priced?
Keepr lids are priced at CA$0.30/cm³ of finished printed material, including supports and printed accessories. See your exact quote in the builder. Shipping and taxes are calculated at checkout.
What does the Keepr Fit Guarantee cover?
You measure your tank and approve the production drawings. We manufacture to that approved design. If the lid still does not fit, Keepr will remake it free under the Fit Guarantee terms. You pay shipping for the remake.
