Simpson Strong-tie LUC210Z Concealed Flange Joist Hanger

Product Description

The SIMPSON STRONG-TIE LUC210Z is a concealed flange joist hanger designed for 2x10 lumber in structural framing applications. Formed from 18-gauge ZMAX galvanized steel, it delivers corrosion resistance suited for treated lumber and exterior exposure. The concealed flange design hides the connector behind the face of the framing member, producing clean sight lines in exposed conditions such as overhead decks. Licensed contractors and framers install this hanger where a standard face-mount hanger would be visible or where end-of-ledger and header conditions require a low-profile connection detail.

This hanger is commonly used in residential and light commercial deck framing, floor systems, and roof structures where clean aesthetics matter or where ledger and header end conditions limit the use of conventional face-mount hardware. It is also suitable for post-to-beam connections requiring a concealed attachment. The LUC210Z fits the same product family as concealed hangers available for 2x6, 2x8, and 2x12 lumber, making it part of a coordinated hardware system across a single framing layout.

Compatibility

Designed for use with 2x10 nominal lumber. The concealed flange hanger series is also available for 2x6, 2x8, and 2x12 members within the same product line.

Installation Notes

Installation is performed by licensed framers or structural contractors following applicable building code requirements, including IRC and IBC fastener schedules. Use only the nail type and quantity specified in the manufacturer load table for this hanger size — substituting fasteners reduces rated capacity. Ensure the framing member is fully seated in the hanger seat before driving fasteners. Do not install on lumber with visible splits, checks, or moisture content above code-permitted levels.
