Installation Guide: Hi-Flo Inside Miter
What is the Hi-Flo Inside Miter ?
The Hi-Flo Inside Miter is an Inside Miter for use with BEST-1 Gutter Guards. The design handles the high water flow
conditions that are caused by roof valleys. The Hi-Flo Inside Miter 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. Miter slows the water down using the Raised Ridges built into the screen.
2. Miter ridges changes the direction of the water flow to increase the water going into the gutter.
3. Miter has a larger & stronger 24 mesh Stainless Steel screen to allow for faster water absorption.
4. The Raised Screen keeps debris lifted up to be blown off, while only water runs into gutter.
These features work together to make the Hi-Flo Inside Miter the best solution for inside miter miters.
Hi-Flo Inside Miter is easy to clean with either a brush or leaf blower if needed.
