If you don't want a sagging or leaning water feature, then use this heavy duty grate to keep it upright and level. The sturdy, self supporting grate platform requires no additional support for most water features. It is commonly used to cover water basins or reservoirs that support bubbling rocks, fountain vases, pottery or faux rocks. You can also use this strong black grate to construct a pondless waterfall or different pondless water feature.

Duronet Hardware Cloth Plastic Mesh is available to keep out fine debris.

  • The 24" x 24" size is cut to size from a larger 24" x 48" grate, so will have one cut edge.
  • We recommend adding support blocks under the grate's center for any fountain, stone or other feature that weighs over 50 pounds because even a heavy duty grate can sag in time without support. With cinder blocks added beneath, this grate can support up to 1,000 pounds.
  • This product is only a support grate. Basins, reservoirs and pond liners to create water features are sold separately.

    Awesome for Other Uses

    Posted by Karin White on Aug 3rd 2021

    This is our second purchase of the same grate. It is extremely sturdy, straight not bent or warped, and was perfect size 24x24. We used it as a cover up paver, to go over our sprinkler box and become part of the pavered hard scape. It serves as a drain as well for water off of the paver patio.. and we sit on top of it our flower pots to further disguise the sprinkler access box. We love it and have one for each side of our patio where we needed to cover up. The color is a gray / black charcoal with variations in the color that match perfectly our gray/charcoal gray paver stones. I wish I could share a pic of how gorgeous this turned out. We are so HAPPY! Thanks!

    Heavy duty fountain grating

    Posted by Artfully Rogue on Jun 28th 2021

    I build several water features a week and this is by far the best plastic grating that I have found online. At 185lbs I've stood on this grating and it didn't budge at all. On occasions I've had to trim the grating to fit my water features and it still maintains its strength while resting on two one inch supports that run the length of the grating. This would be great in a variety of water features where you need something strong enough to hold decorative over your basin.

    Works like a charm.

    Posted by Doug Boyd owner of Artfully Rogue on May 19th 2021

    I make several different sizes of water features and whether its intended or not, I will often cut the plastic grating to size and it is just as sturdy and strong. I usually buy 4 or 5 at a time and shipping is fast and order status updates for great.

    Sturdy Grate

    Posted by Matthew M on May 4th 2021

    These are sturdy, high quality grates. I have placed them over the 100 gallon, in-ground tub that holds the water for my backyard water feature, which involves water flowing down river rock, then over a basalt slab and into the tub. I used two 24" x 36" grates and one 24" x 24" grate. For support, I created two towers inside the tub with 3 cinder blocks per tower (holes facing sideways). Placing the grates on the side of the tub plus on the cinder blocks allows you to stand on them without them flexing. I will place a single layer of river rock over the grates to make the water feature more attractive.

    Easy to install and well built

    Posted by Laurence Michaels on Dec 8th 2020

    Installed this product with no trouble and it appears well built. Given the weight of my fountain I placed a concrete block (recommended) under the center of the grate. Would recommend to any home owner looking to create an outdoor water feature.

    Great quality grate for our water feature

    Posted by wbnielson on Nov 12th 2020

    We had an old rusty metal grate that held river rocks up and the water practically disintegrated it. This is much higher quality and very solid. Highly recommend.

    24x24 grate review

    Posted by Randal H on May 5th 2020

    My fountain reservoir requires a 24x24 inch grate and this product fit just fine. It is heavy duty as expected. I gave 4 stars because the 24x24 is actually half of a 48x48 grate which has been cut down the middle and that leaves one edge without a strong border support.
