Assess the space
Locate each exposed service opening and any drop beneath it. Keep necessary access for maintenance in the plan.
Choose the right materials
Compare reinforced borders and UV-treated mesh if the opening is exposed to sun and rain.
Plan the installation
Have fixings assessed on site; anchors in a weak surface or a loose edge can compromise coverage.
Keep it in good condition
Inspect after any AC servicing or duct work to ensure the net has been restored correctly.
Questions for your site visit
Ask how technicians will access equipment and how the net will be reinstated afterward.
