Review: Super easy, simple product, great quality - This product is just simple mesh, cut and formed for the specific use of gutter protection. There is a perfect balance between rigidity/thickness and how bendable it is, and it is easy to cut with tin snips. I only have 40 linear feet of gutter, so I was able to do the job in a few hours. I have a 4" gutter, so the width of this product is more than is needed, but it tucks neatly under the roof tiles. In the few places where the roof material was unyielding and I could not tuck much of the mesh underneath, I simply trimmed the mesh shorter to fit. All that is needed is a pair of supple work gloves, a good pair of tin snips, a power drill with 1/8 bit, some small screw and screwdriver. I placed 2 screws per section which is plenty to anchor the guards no matter how strong the wind blows (screws do NOT come with the product). I strongly recommend the gloves, as there are sharp edges and barbs along the cut edges of the mesh that will nick your hands without protection. The mesh of this product is rather large, which is fine to block big leaves that clog gutters around here, but if you live in an area with trees that drop a lot of fine or very small crud, then you might want something with a finer mesh. The other consideration that I am dealing with is the steep pitch of my roof; water runs fast into the gutter, therefore gutter guards with a fine mesh can actually cause the water to "bounce off" and not trap or catch enough of the runoff. This is another reason that these Amerimax guards are perfect for my needs. Overall this is a great product that is easy to install and should perform as intended for several seasons. Review: Installation Tips and Troubles - Corrected to indicate that I have K-style gutters, not ogee. I used 3 75-foot containers of the gutter screens. They are quite stout and simple to use. I have 5-inch K-style gutters with long nails about every 3 feet driven through the very top section of the gutters with very little space between the top of the nails (aluminum spacers covering the nails) and the bottom of the lip of the top of the gutters. To use these screens, I had to use sheet metal snips to cut back the lower part of the screens so that the spring ridge (lower part) of the screens could fit between the nail/cover and the gutter lip inside. I had both inside and outside 45 degree corners to fit, so custom cutting was required many times. The screens appear deep enough to use on 6 or 5 inch gutters, so they have to tuck up quite deeply under my shingles in my 5 inch application. I found that at corners in particular, cutting some of the top (back) of the screens made insertion easier/possible. Also note that it required quite a bit of lifting of shingles, so don't try this on a cold day or you may crack/break shingles. The ends of the screen runs leave a triangular opening through which a few leaves/needles might enter -- would be nice to have a snap-on end-cap available at extra cost for those who want it -- bending the screens down is not elegant nor totally effective. One key tip: the screens come with a slight crown. You definitely want to reverse that for the first inch or two at the back as that will allow them to slide above the drip edge and below the shingles more easily, depending on how high your gutters on mounted on your facia. Note that if you don't have ladder spreader arms to keep your ladder supported by the roof and not the gutter, the ladder will compress the gutter and hence your screen installation will be more difficult, plus when you remove the ladder the screens may not slide out fully to the gutter edge and you may have a gap. Highly recommend using the ladder spreader support arms during installation where possible. Another trick: take a metal coat hanger and bend a small right angle on one end. Use that as a tool to manipulate the screens -- once they are tucked under the shingles, moving them left to right or front and back becomes very difficult. Having a tool that can be inserted into the screen's holes makes it much easier (though not easy). Where the screens are to overlap, there is a nice cut-out on the front edge. I found that under the shingles it was very hard to slide one over the other. I arrived at the solution to insert the "top" screen section over the existing/under section and then slide the top screen "off" of the under section until the overlap was as desired, rather than trying to slide the "top" section "onto" the existing section. So, start with more overlap than needed, not the other way around. Overall, I found the product excellent. Installation is a bunch of work, on a ladder, with sheet metal snips. I would say my total installation period was at least 10 hours over 3 days. Every screen had to be cut, for at least the nail issue. Obviously, the long, straight gutter runs were much easier and faster. I have a deluge of maple seeds in the spring and live in a forest so many Fall leaves. I also have a neighbor's very tall pine tree with long thin needles that find their way to my gutters. If I encounter any of those being able to breach the screens, I will update this review. Good luck. ## Features - Durable construction, sturdy steel screen, powder coated black - Designed to lock on to the front edge of the 5 in.

It doesn't say on the description. You should change that** A: The screen is 36" or 3 feet long. Also, just like nearly all Amazon products a description & LENGTH (in this case)is listed. Just scroll down!! **Q: I installed these and noticed ice sickles forming on gutter edges when snow melts. Is this something I should be concerned about?** A: The simple answer is No. Under cold damp weather conditions, moisture can collect and freeze before it has a chance to drip off guttering. With any gutter guard system, the slow moving frozen moisture can fill the perforations of the gutter guard which will allow moisture to slow over the edge of the gutters. As the buildup of ice forms, each lot of freezing moisture flows over the existing frozen drip and forms ice sickles. When the sun comes out and warms the guttering and gutter guard, this situation will quickly resolve itself. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Super easy, simple product, great quality *by M***B on October 3, 2020* This product is just simple mesh, cut and formed for the specific use of gutter protection.

I bought one box which covered my whole house with three sections left over. I'll keep these spares in the garage, although I doubt I'll need them. Measure first, and buy enough. One box is roughly 70 feet, (NOT 75 because each section overlaps by half an inch, and because with each run you'll be cutting a piece in half.) I found installation very easy using almost zero tools but there were a few small issues and I have a few tips. 1) After cleaning my gutters and thoroughly flushing the downspouts, I learned that the "low end" isn't where the downspouts are located. I've read that it's best if I adjust the height of the gutter so they're higher by 1/4" for every 10 feet. If you're going to do this, do it at this point. Although I didn't do this, (and may regret it later) I noticed that you don't need a level... Water itself will tell you if it's running toward the downspout, and in my book that's good enough. 2) Make a very simple but handy tool: Straighten a wire coathanger, then bend 1/8" of the tip at a 90 degree angle with pliers and form the other side so you can grip it to pull. You can use this to "hook" into the mesh to manipulate it around as you overlap the ends of each section. You'll find that the previously-placed piece will shift back under the shingles when you place the new one, so this helps. I also tried a large paperclip with a loop over my index finger which worked fine too, but after I lost it in the weeds I went with the coathanger. 3) In some spots, the gutter guards wouldn't slip far enough under. In those areas I cut some of the gutter guard away. You'll also have to cut the "final" piece at each run for a proper fit. 4) Yes tin snips would work, but for speed and straight cuts I used an angle grinder with a cutoff wheel (And when I say use safety goggles, I REALLY mean it for this job!) A Dremel with a heavy-duty cutoff wheel would also work and would probably get better results. File or heavy-grit sand the ends to get rid of cutting points. 5) In my case I have asphalt shingles, which flex, so this probably made things easier. Although instructions say put the mesh under shingles, in my case the underlayment goes all the way to the edge, so I put the mesh under the underlayment. Probably not critical but it seems less likely to damage the underlayment that way. 6) In a few places there were nails in the wood, below the underlayment. They catch in the mesh. If you find it won't go under far enough, check for a nail and lift it up over the nail. 7) I found it easier to go right-to-left than left-to-right, because the piece on the left should go above the piece on the right. ## Frequently Bought Together - Amerimax Home Products 636025 Lock-In Gutter Guard, Black, 25 Count (Pack of 1) - BOPOWO Self-Tapping Gutter Screws White Painted Slotted Hex Washer Head #8 x 1/2" Zinc Plated Finish, Includes 1/4" Magnetic Hex Driver - for Gutter - HURRICANE 10 Inch Aviation Tin Snips, Heavy Duty Metal Cutter Shears for Cutting Sheet Metal, Straight Cut, Chrome Vanadium Steel --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/22748609-flex-drain-441-253-5-in-lock-on-gutter-guard](https://www.desertcart.us/products/22748609-flex-drain-441-253-5-in-lock-on-gutter-guard) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-07*
