Product Overview

Amerimax's Black Metal Lock-in Gutter Guards can be used on 4 in., 5 in. and 6 in. "K" style gutters. The pre-notched design allows for overlapping which eliminates gaps between the guards. The gutter guards are easy to install - just slide the flat side under the shingle and lock the curved portion in to the front edge of the gutter. This product is designed to handle high volume water flow and hold up to the heat and cold better than vinyl gutter guards.
  • Slides under the shingle eliminating debris accumulation on the shingles behind the guard
  • Durable powder coat paint finish prevents rusting
  • Holds up to the heat and cold unlike vinyl guards
  • Roll formed edge locks to the entire lip of the gutter rather than 2 small clips
  • Black to blend with your home's roof line
  • Works with spike/ferrule and all hidden hanger installed gutters
  • 10-year limited warranty

    Great product. Made in the USA
    Overall I'm very satisfied with these gutter guards. They fit in my 6" gutters perfectly and are practically invisible from the ground. Very easy to install and since I only have oak trees on my property with big leaves, these should work very well.

      Even though we have an underground gutter systems, when it rains quick and hard they tend to overflow at the base. We liked the InvisaFlow Channel Guard because they are wide and can help catch the overflow rain and divert it away from the foundation. We made a cut (not all the way through) on the end just to fold up behind the gutter. And then we made a cut the circumference of the pipe to form nicely around the pipe and sealed it with silicone. We used an Xacto knife to cut through it. This does an excellent job of catching any overflow when needed. You can be a little creative on how you use it. It would also work great if you let your gutter just drain into it as well.
        Looks sleek and installs easily
        These are way better than the white plastic ones I bought years back. They lock in easily and look clean and sleek once installed. The distance between the edge of my gutters and my shingles isn't that far, so I had to tuck the guards under the shingles, which worked well. Now just to wait a year or two to see how they hold up. Very satisfied so far.

            Easy & inexpensive solution
            Problem: ugly downspouts. Very simple to install & blends into the landscaping very nicely. Very cost effective & simple to put together if you need a longer run.

              I bought 5 of these to use as splash blocks. The blue ones that came with the house were gross so I saw these and a light bulb went on. I just laid it in place and filled it with river pebbles. It works great and the rocks are far more attractive than those blue ones and I imagine less expensive.

              If you live near maple trees, stay away from these.
              Have had them on for one year, and of course this year is the year maple trees are bad. These leaf guards are perfect at catching them. I have maple seeds sticking out in masses along all the gutters on the front of my house. They work fine for regular leaves, but with maple trees, I'm now having to hire someone to come clean my gutter guards, which kind of defeats the purpose of them.

                Expect modifications
                I agree with the reviewers who stated the product needs modifications. I followed the instructions from one of the reviews, plus one additional step.....since the bottom of the channel has to be flush with ground level, I splayed the sides a bit and secured them with edging stakes; otherwise, I felt the sides stuck up too high. It also helped to make the end wider, which looks nice. I think a similar result could be achieved with landscape edging and sheet plastic, which I plan to try in the front, where I prefer more organic curves. When installed correctly, they do funnel water from the house. Also, the price is right, which makes up for the few minutes spent making alterations.

                  Bargin gutter guard
                  Cost effective solution to clogged gutters..... this extremely simple to install Gutter guard is very effective in keeping most debris out of your gutters.... The only thing I have found that sometimes gets through is Pineneedles.... but that's only if they land perfectly.... otherwise everything else stays on top and blows off and if not it is very simple to clean off by using a blower.... inexpensive... easy to install... easy to work with.... and above all it works!!!... highly recommend to anyone looking into gutter guards
