The Simpson LSCZ Adjustable Stair-Stringer Connector is an 18-gauge ZMAX galvanized steel connector engineered to create a versatile, concealed connection between the stair stringer and the carrying header or rim joist while replacing costly framing. Field slopeable to all common stair stringer pitches, this stringer connector works with either solid or notched stringers and is interchangeable for left or right applications - making it a dependable, flexible solution for a wide range of stair framing projects.

Key Features

• Replaces additional framing and toe-nailing - simplifies the stair framing process and reduces material and labor costs on the job site.
• Suitable for most installations on nominal 2x10 or 2x12 header/rim board - fits the lumber dimensions most commonly used in residential and light commercial stair framing, minimizing compatibility concerns.
• May be installed flush with the top of the carrying member or lower on the face - gives installers placement flexibility to accommodate different stair designs and site conditions.
• Interchangeable for left or right applications - a single connector handles either side of a stair assembly, so you do not need to stock separate parts for each orientation.
• Made from 18-gauge steel - provides a sturdy, dependable connection without adding unnecessary bulk to the stringer assembly.
• ZMAX galvanization offers extra corrosion resistance - makes the connector suitable for interior and some exterior applications where standard galvanized coatings may fall short.

Why This Product

• One connector, multiple configurations - because the LSCZ is field slopeable to all common stair stringer pitches and works with both solid and notched stringers, a single connector model adapts to the most common stair framing scenarios rather than requiring multiple specialized parts.
• Concealed connection that cuts framing costs - the LSCZ creates a hidden connection between the stringer and the carrying header or rim joist while directly replacing additional framing members and toe-nailing, helping reduce both material expense and installation time.
• Enhanced corrosion protection for demanding environments - the ZMAX galvanized coating delivers extra corrosion resistance beyond standard zinc coatings, extending the connector's reliable service life in interior and select exterior stair applications.
• Made in the United States by Simpson - backed by the engineering standards and quality control that professionals rely on for structural connectors in stair and floor framing applications.
