FEI-RONG 48-Inch Aluminum Folding Square – Adjustable 45° & 90° Angles for Framing

Meet the FEI-RONG 48-Inch Aluminum Folding Square, a versatile tool built for professional carpentry and home workshop projects. With an extended 48-inch scale, it helps you establish precise layouts for framing, roofing, and stair installations, while staying compact enough for transport between job sites. The quick-read markings and robust construction make it a practical companion from rough framing to fine trim work.

Durability is built into the design. The frame uses aluminum with a carbon steel core, delivering strength without adding unnecessary weight. The die-cast construction provides stable readings across repeated use, and the non-glare matte finish with black graduations remains legible in varied lighting conditions. This combination aims to withstand daily wear while keeping measurements consistent.
