The Simpson Adjustable Truss Hanger Skewed Left 45 deg. is a field-adjustable, U-shaped hanger built to support 4x floor trusses and 4x beams where a precise 45 deg. left-hand skew is required. Constructed from 16-gauge steel with a G90 zinc galvanized coating, this hanger features positive-angle nailing (PAN) and extra-long straps that make it a practical, single-product solution for both top-flange and face-mount applications on the job site.

Key Features

• Field-adjustable design eliminates the need for special orders - one hanger adapts on site, reducing procurement delays and keeping projects on schedule.
• Compatible with top-flange and face-mount installation - gives contractors the flexibility to use the method that best suits the framing condition without sourcing a second hanger.
• Extra-long straps for height adjustability - makes top-flange installation more convenient in the field and helps fine-tune positioning without additional hardware.
• Positive-angle nailing (PAN) - helps eliminate splitting of truss bottom chords, protecting structural integrity during fastening.
• 45 deg. left skew - engineered specifically for left-skewed framing connections; the companion right-skew model is the THAR422.
• Minimum carried member of 4x10 - confirms compatibility range upfront so installers can plan connections with confidence.
• Made from 16-gauge steel - delivers the strength needed for floor truss and beam support applications in residential and light commercial framing.
• G90 zinc galvanized coating - provides extra corrosion resistance, making this hanger well-suited for demanding construction environments where moisture exposure is a concern.

Why This Product

• One hanger, two installation methods - the ability to switch between top-flange and face-mount configurations means fewer SKUs to manage and greater adaptability when field conditions change.
• Built-in adjustability reduces job site delays - the extra-long straps allow height fine-tuning on the spot, so crews are not waiting on custom or special-order components to fit non-standard framing layouts.
• Structural nailing protection where it counts - positive-angle nailing (PAN) actively reduces the risk of splitting truss bottom chords, a common concern when securing hangers to engineered lumber members.
• Durable galvanized construction for long-term performance - the G90 zinc galvanized finish on 16-gauge steel provides reliable corrosion resistance, helping this hanger maintain its load-carrying integrity in both interior and exposed framing environments.

Frequently Asked Questions

What is the skew direction of the THAL422, and what is the equivalent right-skew model?

The THAL422 is skewed 45 deg. to the left. For an equivalent hanger with a 45 deg. skew to the right, order the THAR422.

Can the THAL422 be used for both top-flange and face-mount installations?

Yes. The THAL422 is designed for use in both top-flange and face-mount installation configurations. Its extra-long straps provide the height adjustability needed to accommodate top-flange installation conveniently in the field.

What fasteners are required to install the THAL422?

The THAL422 should be installed using 0.148 x 1-1/2 in. nails and 0.148 in. x 3 in. nails. Refer to the load table for minimum and maximum nailing configurations and specific nailing requirements.

What corrosion protection does the THAL422 offer, and what steel gauge is it made from?

The THAL422 is made from 16-gauge steel and features a G90 zinc galvanized coating, which provides extra corrosion resistance and makes it suitable for demanding construction environments.
