1. Block Dimensions
This section lists various blocks identified by Roman numerals and their corresponding dimensions in millimeters (length x width x height), with an additional thickness indicated as (+12). Key blocks include:

• Block I: 350 x 230 x 118 (+12)
• Block II: 480 x 230 x 118 (+12)
• Block III: 400 x 350 x 118 (+12)
• Block IV (Kitchen): 500 x 350 x 158 (+12)
• Block V: 500 x 300 x 118 (+12)
• Block VI: 500 x 350 x 118 (+12)
• Block VII: 800 x 300 x 118 (+12)
• Block VIII: 600 x 350 x 118 (+12)
• Block IX: 600 x 400 x 118 (+12)
• Block X: 1100 x 350 x 118 (+12)
• Block XI: 1400 x 300 x 118 (+12)
• Block XII: 1790 x 300 x 118 (+12)

2. Sink Dimensions and Types
Several sink models are specified with dimensions and types, including oval and round sinks. All sinks are designed to be attached underneath a 12 mm thick DURATOP surface.

• Oval Sinks:
  • Oval I: 400 x 260 x 138 (+12)
  • Oval II: 490 x 320 x 143 (+12)
  • Oval III: 600 x 400 x 173 (+12)
• Round Sinks:
  • Round I: 300 x 118 (+12)
  • Round II: 380 x 138 (+12)
• Kehto Sink: 510 x 320 x 138 (+12)

3. Material and Attachment Details
All sinks are designed to be attached from underneath to a 12 mm DURATOP surface, ensuring a flush and secure installation. The thickness of the DURATOP is consistently 12 mm across all models.

4. Additional Notes
- The document includes repeated dimension values and some numeric codes (e.g., EQ 26, 18SINK) which likely refer to internal specifications or quality codes.
- The thickness indicated as (+12) consistently refers to an additional 12 mm layer, presumably the DURATOP thickness.
- The blocks and sinks are standardized in size to facilitate modular design and installation.
- The kitchen block (Block IV) has a slightly increased height dimension (158 mm) compared to other blocks (118 mm), possibly to accommodate specific kitchen requirements.
- The document references DURAT sinks with a date code (3/2008®), indicating a product line or standard date.
