Gratnell's - Tall Treble Frame - 51 Shallow Trays

Organise your lab or prep room with a high-capacity, safety-focused storage system that keeps everything visible, accessible, and securely in place. The Gratnell's Tall Treble Frame is built for busy science departments, offering flexible tray configurations, robust construction, and a clean, professional look that suits any school environment.

Why choose the Tall Treble Frame?

• High-capacity organisation: Store up to 51 trays in a single three-column frame, ideal for lesson kits, consumables, glassware, and small equipment.
• Flexible tray mix: Choose from four tray heights (shallow, deep, extra deep, jumbo) and multiple colours to match your storage needs and visual coding system.
• Safety-first design: Includes a metal top, adjustable feet, and back diagonal bracing for rigidity; can be wall-fixed for full stability in line with health and safety best practice.
• Durable, low-maintenance build: Powder-coated steel frame resists wear, chemicals, and daily classroom use; available in Gratnells Grey, Silver, and White to match your school palette.
• Easy access for staff and students: Open-front tray design makes it simple for teachers and technicians to find, remove, and return items quickly during lessons and prep.

Ideal for

• Secondary science labs and prep rooms
• Sixth-form and college practical suites
• Departments that need to store mixed equipment sizes and high volumes of small items
• Schools looking to standardise storage across multiple labs

Configurations and options

Select a pre-set configuration or build a custom solution:

• 51 shallow trays – Perfect for small parts, worksheets, safety gear, and standard lab kits.
• Mixed tray sets – Combine shallow, deep, extra deep, and jumbo trays to store bottles, boxes, and larger apparatus alongside smaller items.
• ChemStore variants – Integrate shelves with trays for safe, visible chemical storage and clear labelling.
• Empty frame with runners – Start with an empty Tall Treble Frame and add trays over time as your needs evolve.

Trays slot into runner pairs within the three columns, so you can reconfigure the layout as your curriculum or stock changes.
