Turn your circular saw into a precision tool with the Kreg guide rail. It allows straight, accurate, repeatable cuts without the need for measuring and marking. Delivers precise control throughout the entire cut and allows for cutting multiple parts to the same size with a single setup. Enables rip and crosscuts up to 24" wide. The universal sled with reversible guide fits most circular saws — both left- and right-blade — ensuring ease of use. The large handle design provides secure contact and smooth control, reducing fatigue during extended use. Made of high-quality aluminum for portability without sacrificing strength and stability.
