Installation Guide: Straight Hi-Flow section
What is the Straight Hi-Flow section?
The Straight Hi-Flow section is a heavy use gutter guard section for use with BEST-1 Gutter Guards. The design
handles high water flow conditions that are caused by roof areas like around dormers, around roof chimneys,
downspouts on roofs, and straight roof valleys. The Straight Hi-Flow section comes in gray aluminum frame with a
stainless steel screen that matches the BEST-1 Gutter Guard, fully assembled, and fits up to a 6 inch gutter.
2 Install Methods:
✓ Fascia Mount – Attaches securely to the back of the gutter, trim to fit installation to fit most gutters.
✓ Under Shingle Mount - Fits under the roof shingle, easy install, and does not void any roof warranty*
How it Works:
1. Straight Section slows the water down using the Raised Ridges built into the screen.
2. Straight Section has a larger & stronger 24 mesh Stainless Steel screen to allow for faster water absorption.
3. The Raised Screen keeps debris lifted up to be blown off, while only water runs into gutter.
These features work together to make the Straight Hi-Flow section the best solution for high water flow areas.
Straight Hi-Flow section is easy to clean with either a brush or leaf blower if needed.
