The Simpson HSUL410 Heavy Skewed U-Shaped Joist Hanger is a purpose-built structural connector from Simpson Strong-Tie engineered to create a precise 45 deg. angled connection between a 4x10 joist and a header. Designed specifically for left-skewed framing applications, it gives contractors and builders a reliable solution when standard straight hangers simply will not work. Fabricated from 14-gauge steel and finished with a G90 zinc galvanized coating, this hanger is built to hold up in demanding wood framing conditions where both structural integrity and corrosion resistance are required.

Key Features

• Skewed left (HSUL) orientation - purpose-matched for left-side angled framing layouts, eliminating guesswork and field modifications when the framing plan calls for a skewed connection
• Accommodates joists skewed 40 to 50 deg. - provides built-in angular flexibility around the nominal 45 deg. connection, so minor framing variations do not require a different hanger
• Angled nail slots - guide nails into the correct position automatically, reducing installation errors and helping ensure a code-compliant connection every time
• Square cut or bevel cut joist end accepted - gives installers the freedom to prepare the joist either way without affecting fit or performance, saving time on the job
• Sized for nominal 4x10 joist members - a precise fit for large dimensional lumber common in floor and roof framing, delivering a secure, properly loaded connection
• 14-gauge steel construction - provides the structural strength needed to support heavy joist members in residential and light commercial framing applications
• G90 zinc galvanized finish - offers enhanced corrosion resistance compared to standard coatings, making this hanger a dependable choice in moisture-exposed or treated-lumber environments

Why This Product

• Engineered for a specific angle, not a workaround - rather than bending or shimming a standard hanger to fit, the HSUL410 is factory-made for a 45 deg. skewed left connection, which means the structural integrity of the joint is not compromised by field adaptation
• Flexible enough for real-world framing tolerances - the 40 to 50 deg. accommodation range means builders are not locked into a single perfect angle, reducing the risk of a costly mismatch when field conditions vary slightly from the plan
• Simplified installation with guided nailing - angled nail slots take the guesswork out of fastener placement, helping crews work faster and with greater confidence that each connection meets structural requirements
• Long-term durability with G90 galvanized protection - the corrosion-resistant finish is especially valuable in applications involving pressure-treated lumber or exterior-adjacent framing where moisture exposure is a concern over the life of the structure

Frequently Asked Questions

What skew angle does the HSUL410 support?

The HSUL410 is designed to provide a 45 deg. connection between a joist and header, and can accommodate joists skewed between 40 and 50 degrees, offering a degree of flexibility around that nominal angle.

Does the joist need to be cut at a specific angle for installation?

No. The joist end may be either square cut or bevel cut, giving installers flexibility in how they prepare the joist before fitting it into the hanger.

How are nails installed in the HSUL410?

The HSUL410 features angled nail slots that direct nails for proper installation. It is installed with 16d common nails.

What is the difference between the HSUL and HSUR?

The HSUL and HSUR hangers are identical in design except for their skew direction. HSUL is skewed to the left, while HSUR is skewed to the right. The HSUL410 is the left-skewed version sized for a 4x10 nominal joist member.
