Simpson Strong-tie LPC4Z Adjustable Post Cap 4x4 Zmax

Product Description

The SIMPSON STRONG-TIE LPC4Z is an adjustable post cap connector designed to join 4x wood members at right angles with structural reliability. Fabricated from ZMAX galvanized steel, this connector resists corrosion in treated-lumber and exterior applications. It eliminates the need to drive nails into end grain, which is a weaker fastening method that reduces joint integrity. Triangle nail holes are incorporated into the design, allowing additional nails to be added when higher uplift load capacity is required. This part is installed by framing carpenters, structural contractors, and deck builders working on wood post-and-beam assemblies.

The LPC4Z is suited for residential and light commercial framing applications where 4x structural members intersect at 90-degree angles. Typical installations include deck posts, pergola framing, fence post caps, and similar above-ground wood structures. This connector is always installed in pairs, with one cap on each side of the connection, ensuring load transfer is distributed across both faces of the joined members. It is appropriate for use with pressure-treated lumber in outdoor and exposed conditions due to its ZMAX coating.

Key Features

• ZMAX galvanized steel construction for corrosion resistance with pressure-treated lumber
• Adjustable design accommodates 4x wood members at right angles
• Eliminates end-grain nailing for stronger, more reliable connections
• Triangle nail holes allow additional fasteners to increase uplift load capacity
• Always installed in pairs for balanced load transfer across the joint

Compatibility

Designed as an OEM-style structural connector for 4x nominal wood framing members used in residential and light commercial post-and-beam construction.

Installation Notes

Installation is performed by qualified framing contractors or deck builders following applicable building codes and manufacturer load tables. Always install LPC4Z connectors in pairs as specified. Use only approved structural fasteners in the designated nail holes and follow local code requirements for fastener type and quantity when building in high-wind or high-uplift zones. Do not substitute fastener sizes or omit the paired connector, as both actions reduce rated load performance.
