They were off between 3 and 4 degrees which makes them feel like I could slide. By using these shims under the stairs I was able to level them right up and they feel perfect. Good product - I think the quality is excellent, they drilled easily and I’m glad I ordered a bunch of them as I have a few other home projects where I think I can use them. Review: The 7.75-inch length of these shims makes them incredibly versatile and suitable for a wide range of applications. Whether I needed to level a toilet, door, or window frame, these shims handled the task with ease. Their design allows for easy snapping and adjusting, providing precise and stable leveling for my projects. One of the standout features of these composite shims is their durability. Unlike traditional wood shims that can rot and warp over time, these shims are made of a composite material that is resistant to water and weather. I have used them both indoors and outdoors, and they have held up exceptionally well, even in challenging environmental conditions. The shims' construction ensures they won't compress under heavy loads, providing reliable support for various installations. I appreciated their consistent thickness and strength, which made them a reliable choice for heavy-duty leveling tasks. Additionally, these shims are incredibly user-friendly. The easy snap feature allows me to quickly adjust the shim size to fit my specific needs, saving time and effort during installation. The shims are also easy to trim, making them customizable for unique projects. I was also pleased to find that these shims don't splinter or leave residue, making them cleaner and safer to work with compared to traditional wood shims. Overall, I highly recommend the Pro-Grade Composite Shims for anyone in need of reliable, durable, and easy-to-use leveling tools. Their versatility, water and weather resistance, and precise leveling capabilities make them an indispensable addition to any DIY toolkit. Whether you're a professional contractor or a DIY enthusiast, these shims will undoubtedly make your leveling projects a breeze. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B071FRHGXX | | Are batteries included? | No | | Customer Reviews | 4.6 4.6 out of 5 stars (2,043) | | Date First Available | 16 October 2017 | | Item Form | Sheet | | Item Weight | 570 g | | Item part number | Never Rot Composite Shim | | Manufacturer | Pro Project Supply | | Net Quantity | 24.0 Count | | Number of Items | 24 | | Package Dimensions | 21.3 x 12.6 x 4.6 cm; 570 g | | UPC | 817244023647 | ## Product Details - **Brand:** PHYXOLOGY SUPPLY - **Item Diameter:** 8 Inches - **Item Thickness:** 0.26 Inches - **Material:** wood - **Shape:** flat ## Images ![Pro Project Supplys Never-Rot 8 Inch Composite Shims, 24 Pack.

They are a light composite material that feels quite brittle. If you really need to fix them in place I would suggest drilling a hole in them and then nailing or screwing them down through the hole. **Q: how wide are they?** A: They are 1.5" wide Thanks for reaching out! Thank you. John Customer Concierge **Q: Could these level a 20 gallon aquarium ?** A: If you are asking whether it will handle the weight of 20 gallons of water in addition to the weight of the tank and its stand, I don't see why not. I am using these to lean back to the wall two 4' solid wood bookcases placed on top of each other with mending plates (so 8' tall bookcase) filled with approximately 3000 dvds. However, I would probably at least lower the water level in your aquarium since if you can't empty it first since the water is likely to slosh around a bit. I would more be worried about whether the stand your aquarium sits on has the right leg design to withstand the shock of using these shims to level a 20 gallon aquarium if you plan on doing it while there is water in the aquarium. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by D***B on 13 October 2025* I have installed some aluminum stairs at my house which have sagged a bit - GRRRR!
