1. 90-Degree Setting for Exact Cuts Our right-angle guide rail guarantees precise 90° cuts with no re-adjustment, reducing the time required to complete 90-degree work. The saw rail clamp allows quick and precise setting of the cut or milling angle, which is very practical. 2. Edge Support for Stability and Accuracy The right-angle guide rail includes parallel edge support for steadier, more accurate cutting. It is easier to use square guide rails with edge support. The integrated quick-release secures the angle stop on the guide rail, so your circular saw won’t slip. 3. Aluminum Alloy Construction This right-angle guide rail for circular saws is made from high-quality aluminum alloy and resists damage or bending. The CNC-machined, one-piece aluminum fence provides precise and repeatable 90° cuts, ideal for precise, repeatable cuts in furniture making, sheet cutting, and angle work with a plunge saw. 4. Easy to Use The square right-angle guide is simple to install and remove, and delivers precise cuts. The rail angles are a must-have for circular saw guides. Simply install the guide-angle with your saw and you can achieve accurate square 90-degree cuts faster, saving time. 5. Typical Uses - Cabinetmaking and furniture fabrication requiring accurate 90° joints and repeatable cuts - Cutting sheets and panels (plywood, melamine, etc.) with a plunge saw for clean, square edges - DIY projects and renovations that require quick, reliable square cuts and consistent results
