The Simpson LSUBH3.25-R150 is a 3-1/4 in. light-duty CFS bridging connector built for cold-formed steel framing professionals who need reliable wall stud bracing without sacrificing installation speed. Engineered by Simpson Strong-Tie specifically for CFS applications, this 20 ga. connector features a compact profile that allows standard 1-5/8 in. studs to be sistered directly against adjacent studs, keeping framing layouts tight and clearance issues off the table. From curtain-wall construction to general wall bracing, the LSUBH3.25-R150 is suited for light to moderate wind- and load-bearing situations, and its G90 zinc galvanized finish gives it the corrosion resistance that demanding jobsite conditions require.

Key Features

• Single-installer design - one person can complete the installation without a second set of hands, reducing crew requirements and accelerating the overall framing schedule.
• Many applications require only one screw - minimizing fastener count per connection cuts labor time significantly, translating directly into lower project costs and higher daily productivity.
• Tested to include stud-web strength and stiffness in tabulated design values - engineers and inspectors can rely on published load data that reflects real-world performance, simplifying specification and approval.
• Compact profile accommodates sistered 1-5/8 in. studs - adjacent studs sit flush without awkward gaps or offsets, producing cleaner assemblies and maintaining intended stud spacing.
• Accommodates single members from 33 mil (20 ga.) to 54 mil (16 ga.) - the LSUBH handles a practical range of CFS member thicknesses, giving you flexibility across varying project specs without switching to a different connector series.
• Suitable for light to moderate wind- and load-bearing situations - purpose-matched to the load demands of curtain-wall and standard CFS bracing work, so you are not over-engineering or under-building the connection.
• G90 zinc galvanized finish - provides a durable corrosion-resistant coating appropriate for typical CFS framing environments, helping connectors hold up over the life of the structure.
• Made from 33 mil (20 ga.) steel - the connector material matches the lightest compatible stud thickness, ensuring the clip itself does not become the weak point in a light-duty bridging assembly.

Why This Product

• Engineered for speed on CFS jobsites - the combination of single-installer installation and single-screw connections in many applications means bridging runs get completed faster, keeping CFS framing projects on schedule without adding labor.
• Flexible compatibility across a broad range of CFS members - with flexible design solutions for web thicknesses of 33 mil (20 ga.) through 97 mil (12 ga.) and stud sizes from 3-5/8 in. to 8 in., one connector model can serve multiple phases or zones of the same project.
• Compact profile solves a real layout problem - the purposeful design that allows standard 1-5/8 in. studs to be sistered directly against adjacent studs eliminates a common clearance headache, reducing field adjustments and rework.
• Simpson Strong-Tie quality with load-tested values you can spec with confidence - design values include stud-web strength and stiffness, giving structural engineers and inspectors verifiable data to back up every cold-formed steel bridging and bracing connection.
