Guide to STEP 3

How to take measurements

Accurate measurement is essential to ensure a quality installation.

In Phase 1, identify potential anchor points and measure the distances between them.

At this stage, measurements can have a tolerance of a few inches. The final measurements will be confirmed once the anchors are installed.

In Phase 2, once the anchors are in place, precise measurements must be taken.

IMPORTANT: All required measurements refer to the anchor points, not the actual fabric dimensions.

The system will automatically calculate the fabric dimensions.

Measuring the Space

PHASE 1: Use a rigid tape measure to measure the area where you plan to install the sail, considering any obstacles such as walls, trees, or other elements that may affect the installation.

PHASE 2, use the measuring tape provided with the anchor shipment to measure angles and sail diagonals with great precision.

Measurements should always be taken from anchor point to anchor point.

IMPORTANT: If you decide to install the sail with an inclined winding roller, the actual distance between point A and point C will be greater than in a perfectly horizontal installation. This happens because tilting the roller increases its length compared to a parallel ground installation.

How to Identify Side AC (Roller Tube)

The AC side is conventionally referred to as the roller tube side.

In a quadrilateral (four-cornered sail), AC corresponds to the diagonal.

In a triangle (isosceles, scalene, equilateral), side AC corresponds to one of the sides.

Example: Quadrilateral Shape

Example: Isosceles, Scalene, Equilateral Triangle

In a right triangle, side AC corresponds to the hypotenuse.

Example: Right Triangle Shape

IMPORTANT: See corner constraints for points A and C in the specifications at the bottom of the page.

IMPORTANT: If you install the sail with an inclined roller tube, the actual distance between corner A and corner C will be greater than in a perfectly horizontal installation. This is because tilting the roller increases its length compared to a parallel ground installation.

TIP: We recommend NOT tilting the roller towards corner A, as this is where the motor is.

Constraints for Motorized Roll-up Sail Design

General Constraints

To ensure project feasibility, it is essential to respect some technical constraints when designing the motorized roll-up sail.

• Angle A: Always where the motor is installed, serving as the main reference for the entire configuration.
• Side AC: This diagonal corresponds to the roller tube and must meet specific measurements to ensure optimal stability and fabric tension.
• Side AC Dimensions:
  • Minimum length: 7 feet
  • Maximum length: 26 feet

Special Constraints for Triangular Sails

• Maximum area: 215 ft²
• BF measure, perpendicular to AC (roller tube), can be up to 16 feet long.

• Angles A and C must be ≤85°.
  For simplicity, corner B must necessarily remain within the roller tube outline to roll up correctly.

Special Constraints for Quadrilateral Sails

• Maximum area: 323 ft²
• Angles A and C must be ≤85°.
  For simplicity, angles B and D must remain within the roller tube outline to roll up correctly.

• The difference in length between DE and BF must not exceed 20 inches, as shown in the diagram.

• Side AC (roller tube) must always be longer than sides DE and BF, as shown in the diagram.
