The Simpson LRU28Z LRUZ ZMAX Galvanized Slopeable Light Rafter U Hanger is an economical, field-adjustable connector designed for rafter-to-ridge beam connections using solid sawn rafters. Built by Simpson from 18-gauge steel with a ZMAX galvanized finish, this hanger's open design allows it to be installed either before or after the rafter is in place - eliminating on-site angle mismatches and delivering comparable or better load capacity than competing rafter hangers while requiring fewer fasteners at a reduced cost.

Key Features

• Open design with field-adjustable slope - lets you set the hanger before or after the rafter is in place, cutting installation time on both new construction and retrofit jobs
• Accommodates roof pitches from 0:12 to 14:12 - covers the full range of common residential roof slopes with a single hanger, reducing the need to stock multiple hanger types
• Slopes up or down to 45 deg. (12:12) - for slopes greater than 45 deg. up to 49 deg. (14:12), allowable loads are 0.85 of table loads, giving you clearly defined load guidance across the entire pitch range
• Fasteners positioned high on the hanger face - allows the bottom of the rafter to hang below the ridge beam for added framing versatility in complex roof configurations
• Compatible with nominal rafter sizes 2x6, 2x8, and 2x10 - one hanger model works across multiple lumber dimensions, simplifying procurement and reducing waste on the job site
• ZMAX galvanized coating - provides extra corrosion resistance for exterior applications and use with pressure-treated lumber, helping the connection maintain its structural integrity over time
• Made from 18-gauge steel - delivers reliable strength while keeping material cost low, making this hanger an economical choice without sacrificing performance

Why This Product

• Eliminates costly angle mismatches in the field - the field-adjustable seat means crews can dial in the correct slope on the spot rather than waiting on special-order hangers cut to a specific pitch, keeping projects on schedule
• One hanger, wide pitch range - coverage from flat 0:12 up to steep 14:12 means this single slopeable rafter hanger handles the vast majority of residential roof framing scenarios, reducing the number of SKUs a contractor needs on hand
• Comparable or better load capacity with fewer fasteners - Simpson's design achieves strong rafter-to-ridge performance without requiring an excessive fastener count, saving both labor time and hardware cost per connection
• Built for exterior and treated-wood use - ZMAX galvanization makes this hanger a dependable choice where moisture exposure or chemical preservatives in treated lumber would accelerate corrosion on standard galvanized connectors

Frequently Asked Questions

What roof pitch range does the LRU28Z accommodate?

The LRU28Z accommodates roof pitches from 0:12 to 14:12. It slopes up or down to 45 deg. (12:12). For slopes greater than 45 deg. up to 49 deg. (14:12), allowable loads are 0.85 of table loads.

Can the LRU28Z be installed after the rafter is already in place?

Yes. The LRUZ's unique open design enables the hanger to be installed either before or after the rafter is in place, making it suitable for both new construction and retrofit applications.

What fasteners should be used to install the LRU28Z?

Install with 0.148 in. x 3 in. nails, 0.162 in. x 3-1/2 in. nails, or #10 x 1-1/2 in. or 2-1/2 in. Strong-Drive SD screws.

Why is ZMAX galvanization important for this hanger?

ZMAX galvanization offers extra corrosion resistance, making the LRU28Z well suited for exterior and treated-wood applications where standard galvanization may not provide sufficient protection against the elements.
