Fall arm awnings use two spring-loaded support arms mounted to the building on either side of the window. These arms connect to a front bar that holds the fabric taut. By adjusting the arm angle, you control how far the fabric projects from the wall and what angle of sun protection the awning provides. The arms pivot through a continuous arc, giving you precise control over light and privacy throughout the day.
At 90 degrees, the arms extend horizontally and the fabric creates an overhead canopy, ideal for blocking high midday sun while maintaining a clear sightline outward. This is the position most homeowners use during the middle of the day when the sun is directly overhead.
At 135 degrees, the arms angle downward and the fabric sits at roughly a 45-degree slope. This filters low-angle afternoon sun while still allowing soft light and partial views through the fabric. It is the best position for late afternoon on west-facing windows along the Garden Route.
At 180 degrees, the fabric hangs fully vertical, parallel to the window. This provides complete privacy and maximum glare reduction. Restaurants and guesthouses along the Garden Route use this position during service hours to create intimate dining environments without permanent screening.
90 vs 180 explained: A 90-degree fall arm position creates a horizontal shade canopy above the window. A 180-degree position drops the fabric straight down like a blind. Everything in between gives you a graduated mix of shade, light and privacy. The mechanism is the same. Only the arm angle changes.
