Engineered for precision and built to endure, the Johnson Level 9850-4800 is a professional-grade 48-inch box beam level designed to meet the rigorous demands of both jobsite and workshop environments. Whether you're framing, installing cabinetry, or aligning structural components, this level delivers unmatched accuracy, durability, and ease of use.

Key Features:

• Heavy-Duty Aluminum Construction: Crafted from aerospace-grade aluminum alloy, the frame offers superior strength while remaining lightweight for easy handling. It resists bending and warping, even under tough conditions.
• Triple Vial System: Includes three solid block acrylic vials—two plumb and one level—for precise measurements. These vials are fog-proof, leak-proof, and crack-resistant, ensuring long-term reliability.
• SurroundView® Technology: Enhances ambient light reflection around the vials, making them easier to read in low-light conditions. The magnified curved center block vial improves visibility and accuracy.
• GripTight™ Non-Slip End Caps: Removable anti-slip rubber end caps with wall grips allow for flush corner measurements and hold the level firmly in place with one hand
• Machined Gauging Edges: Precision-machined edges ensure consistent contact with surfaces for accurate readings and layout work
• Soft Cushioned Hand Grips: Ergonomically placed grips provide comfort and control during extended use
• Non-Magnetic Design: Ideal for use around wood studs and non-metallic surfaces. For steel framing, Johnson recommends their magnetic 9550 series
