The baseplate is the structural mounting component where each pergola post is anchored to the ground or surface footing.
Accurate baseplate positioning is essential for stability, proper water drainage, and long-term alignment of your pergola.
⚙️ Baseplate Overview
All Pro+ Pergolas use the same standardized baseplate design across every configuration (Manual / Motorized / Freestanding / Wall-Mounted).
This allows for consistent anchor positioning and footer preparation, regardless of pergola size.
📐 Baseplate Dimensions
Specification | Metric (mm) | Imperial (in) |
Plate Width | 180 mm | 7.087″ |
Plate Depth | 140 mm | 5.512″ |
Thickness | 8 mm | 0.315″ |
Anchor Hole Diameter | 10.7 mm (slot width) × 20 mm (slot length) | 0.42″ × 0.79″ |
Hole Count | 8 (4 corner slots + 4 center holes) | — |
Corner Hole Radius | R10 mm | 0.394″ |
Center Hole Spacing (Horizontal) | 50 mm | 1.969″ |
💡 Tip: The elongated slots (10.7×20 mm) allow for slight adjustment during installation, helping compensate for surface irregularities.
🧩 Mounting Configuration
Each pergola post baseplate features four corner anchor slots (for primary fixation) and four central alignment holes (for reinforcement or drainage).
Baseplates are pre-welded to the post with integrated leveling pads inside the post column.
Corner slots are designed to accommodate M10–M12 bolts or 3/8″–½″ anchor bolts depending on your substrate.

Key Points:
Outer slot-to-slot width: 180 mm (7.087″)
Outer slot-to-slot depth: 140 mm (5.512″)
Central holes: aligned symmetrically for balance.
Corner radius (R10): prevents stress cracking in powder coating.
💡 Tip: When aligning multiple baseplates (e.g., for double bay pergolas), ensure corner-to-corner symmetry and equal spacing based on the “Post-to-Post Measurement” guides.
🧰 Installation Guidelines
Step | Recommendation |
1. Prepare the Footing | Minimum concrete pad size: 400 × 400 × 400 mm (16″ × 16″ × 16″) per post. |
2. Mark Anchor Points | Use the baseplate as a template — mark anchor slot centers before drilling. |
3. Drill Anchor Holes | Use M10 or M12 expansion bolts (or equivalent) based on surface type. |
4. Level the Post | Adjust with washers or shims under the baseplate if surface is uneven. |
5. Seal Anchor Area | Apply weatherproof silicone sealant around anchor points for protection. |
6. Verify Drainage | Ensure pergola drainage holes are not obstructed by anchors or sealant. |
🧭 Compatibility
Pergola Model | Baseplate Type | Bolt Pattern | Quantity |
Pro+ 10×10 | Standard Baseplate | 8-Hole | 4 pcs |
Pro+ 10×13 | Standard Baseplate | 8-Hole | 4 pcs |
Pro+ 13×13 | Standard Baseplate | 8-Hole | 4 pcs |
Pro+ 13×19 (Double Bay) | Standard Baseplate | 8-Hole | 6 pcs |
All Wall-Mounted Models | Standard Baseplate | 8-Hole | 2–4 pcs (front only) |
💡 Tip: All Pro+ baseplates share the same physical dimensions and anchor layout — only quantity per set differs by pergola size.
🧩 Additional Notes
Baseplates are powder-coated aluminum to match post color (Pure White / Dark Grey).
Hidden under baseplate covers for a clean finish.
Drainage channels are integrated inside the post column.
Designed for flush-mount installation on level concrete, deck, or tiled surfaces.
