does it need to be cut to width ?
Asked by: ken
no just cut to length I also cut the 45 degree corners so they fit nicely. Ken they do not stop everything from getting into the cutters. Pine needles still get though.

Customer Reviews

5 in. x 3 ft. Black Lock-On Gutter Guard is rated 4.0 out of 5 by 5.
Rated 3 out of 5 by from GOOD FOR LEAVES; NOT SO GOOD FOR OTHER TREE DEBRIS Installed total of 36' of this gutter guard over my sunroom about 1 year ago. It is easy to install, can be cut with little difficulty and is durable. Once installed it stays in place and is effective in trapping leaves that would fall and clog the gutter. Unfortunately, it is not effective in the spring at my home. I have a silver maple and honey locust tree which shade my sunroom. The "helicopters" from the maple get caught in the guard...hundreds of them...and must be removed by hand. The honey locust drops very fine debris in the spring...lots of it...and easily penetrates the guard, clogging the gutter. The gutter guard must be removed and the gutter debris removed by hand.

Rated 5 out of 5 by from Our gutter gaurds I checked other gutter guards and reviews and spoke to Home Depots Associates. After considering the price factor and the merchandise I decided to try these. They install very easy with the help of the following tools. (see pictures below). the hardest part of the install was putting them under the roofing tiles. They look great and any leaves you see in the picture was in the gutter before I installed the Guards before I finish the complete gutter install I will clean the gutters. I will upgrade this review after a few heavy rains and ice storms.

The manufacturer has reduced the effectiveness of a good product to save money! I bought some guards (and other competitive products as well) to do an evaluation of effectiveness, etc. An experiment. I liked this guard the best for all the reasons mentioned in the other reviews. So I bought more. During installation I noticed they increased the hole size by some 50-80%. What does this do, it saves the manufacturer money by using less metal for the same surface area. What does it do to the product, it lets more pine needles and other tree debris through the guard. More pine needles also "catch" the guard and remain on top of guard. Bad move. Ruin a perfect design!!
