The Simpson LSSR Light Field-Adjustable Rafter Hanger for 4x is a patent-pending, next-generation framing connector engineered for maximum flexibility on complex roof framing projects. Built by Simpson for use with 4x lumber, this rafter hanger solves one of the most common job-site frustrations: it can be installed after all of the rafters have already been tacked into place, keeping the framing sequence intact and eliminating the need to work around connector placement from the start. The flange design allows skew adjustment from 0 deg. to 45 deg., and an innovative hinged swivel seat accommodates slopes up to 45 deg., making it capable of handling a wide range of roof geometries without special-order components. The ZMAX galvanized finish delivers extra corrosion resistance suited to exterior and treated-wood applications where standard hardware falls short.

Key Features

• Post-installation capability - the hanger is specifically designed to be installed after rafters are already tacked in place, so framing can proceed without interruption and connectors can be added at the most convenient stage of the job.
• Flange design for skew adjustment from 0 deg. to 45 deg. - allows on-site skew corrections without cutting, bending, or sourcing angle-specific hangers, reducing material waste and downtime.
• Hinged swivel seat for slope adjustment up to 45 deg. - the seat adjusts easily to match the roof pitch and continues to support the joist securely once set, accommodating steep or irregular roof conditions with a single hanger model.
• 16-gauge steel construction - provides the structural integrity required for load-bearing rafter connections in residential and light commercial framing applications.
• ZMAX galvanization - offers extra corrosion resistance beyond standard galvanized coatings, making this hanger a reliable choice for exterior installations and connections to pressure-treated lumber.

Why This Product

• One hanger handles skew and slope together - with field adjustability for both skew up to 45 deg. and slope up to 45 deg., this connector covers a broad range of roof angles without requiring multiple hanger SKUs or custom fabrication, simplifying material planning on complex jobs.
• Designed around real framing workflows - the ability to install after rafters are tacked in place means contractors are not forced to pre-position hangers before setting members, giving crews more flexibility and reducing the chance of costly sequencing errors.
• Built for demanding outdoor environments - the ZMAX coating is specifically engineered for extra corrosion resistance in exterior and treated-wood applications, making this hanger a dependable long-term choice where moisture exposure is a concern.
• Trusted Simpson engineering - manufactured in the United States to Simpson's established quality standards, the LSSR series represents a purposeful advancement over earlier field-adjustable rafter hanger designs, backed by a patent-pending construction.

Frequently Asked Questions

Can the LSSR410Z be installed after the rafters are already tacked in place?

Yes. One of the key features of the LSSR410Z is that it is specifically designed to be installed after all of the rafters have been tacked into place, making it easier to work with on the job site without disrupting the framing sequence.

How much skew and slope adjustment does this rafter hanger allow?

The LSSR410Z is field adjustable for skew from 0 deg. to 45 deg. thanks to its flange design. It also features an innovative hinged swivel seat that adjusts for up to a 45 deg. slope, allowing it to accommodate a wide range of complex roof geometries.

Is the LSSR410Z suitable for use with treated lumber and exterior applications?

Yes. The ZMAX galvanization coating offers extra corrosion resistance, making the LSSR410Z well suited for exterior and treated-wood applications where standard galvanized hardware may be inadequate.

What fasteners should be used to install the LSSR410Z?

The LSSR410Z should be installed with 0.162 in. x 2-1/2 in. nails as specified for proper load performance and code-compliant installation.
