Shade Sail Mounting Points Installation

This is a guide only, schedules listed are based on typical shade sail installations under normal conditions.

Please Note: The fixings shown here are typical and are based on shade sail installations under normal conditions. Where the structural suitability of a pre existing structure is in question, or you are unsure or have any doubts at all, a local building inspector/contractor or structural engineer should be consulted before proceeding.

Eyebolts

We recommend fitting M10 (min) Collared eyebolts to your uprights before positioning them.

The table below describes the minimum hole size you should use, based on the height of the post above ground level .

Post Height above ground	Footing Size
2.1m – 2.5m	300mm dia x 1300mm deep
2.6m – 3.0m	400mm dia x 1400mm deep

Post Installation

Posts should be set with an approx 5 degree angle leaning away from the sail tension. Allow min 5 days to set before fitting shade sails.

Sail Track (also known as cara groove or annexe track)

The use of sail track is a very popular alternative that produces a flush edge along a wall or facia. The sail track should be fixed at 300mm (min) intervals.

Rafter Brackets

Rafter Brackets are an ideal method to locate fixing points at facia height. Take a roof tile out near the desired position, and locate a roof truss. The Rafter Bracket is fixed to the roof truss with M10 nuts & bolts.
