Designed for precision in tight spaces, it features continuous scribing notches for lumber ripping and clear laser-etched graduations. Durable and reliable, it comes with a limited lifetime warranty, making it a trusted tool for builders and contractors. ## Description This compact 4 1/2" finish square is ideal for access in tight quarters for finish carpentry, setting saw blades and more. CNC machined from extruded aluminum and finished with the same glare-resistant EZ-Read™ anodizing process that made our Johnny Square® famous, this laser-etched square is durable enough to withstand any jobsite abuse, and is backed by Johnson's best-in-class limited lifetime warranty. This rafter square also features continuous scribing notches that are ideal for ripping lumber from 1-1/2" to 3-1/2" as well as handy markers that measure 2x4 board dimensions of 1-1/2" and 3-1/2". Review: Good balance between quality and price - This is a solid square and most importantly, it’s actually square — which is really the entire job. The materials and finish both feel good, and it’s noticeably nicer than the ultra-cheap options without getting into premium professional pricing. I’m not in construction and don’t use every feature these framing squares offer, but for casual woodworking, layout work, and setting up cuts it’s been great. One thing I’ve learned is that starting a project even slightly out of square just compounds problems later and leads to frustration very quickly, so this is not a tool I’d recommend completely cheaping out on. At the same time, I also don’t think most hobbyists necessarily need the most expensive professional-grade square on the market either. This feels like a really good middle ground between affordability and quality. Overall, if you’re a DIYer or casual woodworker looking for a dependable framing square without overspending, this is a good choice. Review: Recommended - This thing is awesome. Big help for small jobs. ## Features - SQUARE LAYOUT TOOL: Made of extruded aluminum; this triangle carpenter square is CNC machined for durability.
