The Simpson LS90Z 7-7/8" Reinforcing Skewable Angle is a load-rated, field-adjustable connector from Simpson built for reliably joining roof rafters to hip rafters and tackling a wide range of structural reinforcing tasks. Its skewable design and ZMAX galvanized coating make it a smarter, more dependable alternative to field-fabricated clip angles, with well-defined fastener locations and tested load values that account for connection eccentricities - giving contractors and DIYers confidence in every installation.

Key Features

• Field-adjustable from 0 deg. to 135 deg. - accommodates members intersecting at a wide variety of angles without cutting or custom fabricating a separate connector on site
• Well-defined fastener locations with tested load values - connection eccentricities are already accounted for in tabulated ratings, so installers can fasten with confidence and avoid guesswork
• 7-7/8 in. length in 18-gauge steel - provides a solid, rigid form factor suited to rafter-to-hip-rafter connections as well as general structural reinforcing applications
• ZMAX galvanized coating - delivers extra corrosion resistance beyond standard galvanized finishes, making this angle connector appropriate for exterior environments and pressure-treated lumber applications
• General utility design with multiple uses - equally at home on professional framing jobs and everyday household repairs or DIY projects, reducing the need to stock multiple connector types

Why This Product

• A cost-effective upgrade over field-fabricated clip angles - rather than bending and cutting custom connectors on the job site, this skewable angle arrives ready to install with load-rated performance that hand-bent clips simply cannot match
• Engineered flexibility for real-world framing conditions - the 0 deg. to 135 deg. field-adjustable range means one connector handles the oblique intersections common in hip-roof framing, reducing waste and installation time
• Built for treated-wood and exterior applications - the ZMAX finish is specifically suited to the corrosive conditions created by treated lumber and outdoor exposure, protecting long-term structural integrity where a standard galvanized connector may fall short
• Consistent, predictable fastening every time - pre-engineered nail hole placement and factory-tested load values remove uncertainty from the connection, supporting code-compliant results on both professional and DIY projects

Frequently Asked Questions

What is the primary use of the Simpson LS90Z skewable angle?

The LS90Z is primarily used as a cost-effective method for connecting roof rafters to hip rafters. It is also a general utility-reinforcing angle suitable for many household repairs and DIY projects.

What range of angles can the LS90Z be adjusted to in the field?

The LS90Z features field-adjustable angles from 0 deg. to 135 deg., allowing it to accommodate members that intersect at a variety of angles.

What fasteners are recommended for installing the LS90Z?

The LS90Z should be installed with 10d common nails.

Why is ZMAX galvanization important for this connector?

ZMAX galvanization provides extra corrosion resistance, making the LS90Z well suited for exterior and treated-wood applications where standard galvanized finishes may be insufficient.
