The Simpson MSTC48B3 44-7/8 in. 14-Gauge Galvanized Pre-Bent Medium Strap is a structural connector from Simpson engineered specifically to transfer tension loads from an upper-story shearwall to a beam on the story below. Pre-bent for precise, ready-to-install fit, this medium strap delivers a simple and versatile solution for critical shearwall-to-beam connections in multi-story wood framing. Its G90 galvanized coating provides extra corrosion resistance, making it a dependable choice for demanding structural applications where long-term performance is essential.

Key Features

• Pre-bent design for shearwall-to-beam tension transfer - arrives ready to install with the correct bend angle, eliminating field fabrication and ensuring accurate load transfer from an upper-story shearwall to the beam below
• Compatible with beams assembled from double 2x members - the minimum 3 in. beam width requirement can be met using doubled-up dimensional lumber, giving framers flexibility when solid timber isn't on hand
• Minimum beam depth of 9-1/4 in. supported - sized to work with standard engineered and dimensional beams commonly used in multi-story wood-framed construction, reducing the need for special accommodations
• Made from 14-gauge steel - provides the structural strength needed for heavy-duty tension connections without adding unnecessary bulk to the framing assembly
• G90 zinc galvanized coating - delivers extra corrosion resistance to stand up to moisture-prone environments, helping protect the connection's structural integrity over the life of the building
• Installs with 10d common nails - uses widely available, standard fasteners so there is no need to source specialty hardware, keeping installation straightforward and code-compliant
• Made in the United States - manufactured domestically to consistent quality standards

Why This Product

• Purpose-built for shearwall continuity - unlike general-purpose straps, this connector is specifically designed to carry tension loads between shearwall levels, making it the right tool for maintaining lateral load paths in multi-story wood construction
• Pre-bent saves time on the job site - the factory bend means installers can position and fasten the strap without bending or cutting, reducing installation time and the risk of field errors on structural connections
• G90 galvanizing for lasting protection - the zinc galvanized finish goes beyond basic coating requirements, helping the strap resist corrosion in conditions where moisture exposure is a concern throughout the building's service life
• Flexible beam compatibility - acceptance of a minimum 3 in. width made up from double 2x members means this strap works with a wide variety of beam assemblies, making it a practical choice for both new construction and repair projects
