The Ultimate Flip Lever Astragal combines enhanced performance with the benefits of enhanced accessibility and ease of use. Just one flip of the easy-to-use built-in lever activates the Floating Boot and Flush Bolt system, securing the unit with two lasting seals, even in imperfect or changing conditions. The Floating Boot and Flush Bolt deliver a perfect seal every time, operating independently of each other to seal against the lowest point on the sill when engaged, while lifting clear of the sill when retracted for lasting, damage-free operation. ULTIMATE FLIP LEVER ASTRAGAL
HOW THE ULTIMATE FLIP LEVER ASTRAGAL WORKS:
With the Flip Lever upright, the Floating Boot and Flush Bolt are lifted clear of the sill.
As the Flip Lever is lowered, the Floating Boot drops independently to seal against the cap.
After the Floating Boot, the Flush Bolt lowers, engaging with the sill regardless of drill hole depth.
