The Simpson Strong‑Tie LPCZ Light Post Cap is a versatile, two‑piece connector designed to secure beams or joists to vertical wood posts in deck, pergola, porch, and other outdoor framing applications. Its adjustable design allows installation on new builds or retrofit projects, providing a stronger mechanical connection than traditional angled nailing. The universal configuration eliminates the need for “left” or “right” specific parts, and installing caps in pairs helps ensure balanced support at each post–beam junction.
Constructed from steel with a ZMAX® galvanized finish, the LPCZ delivers enhanced corrosion resistance compared with standard galvanization, making it well‑suited for exterior, treated‑wood, and moisture‑exposed environments.
Key Specifications:
Connector Type: Adjustable two‑piece light post cap for beam‑to‑post connection
Compatible Lumber: Designed for nominal 4× or 6× posts and beams, depending on model (LPC4Z for 4× members and LPC6Z for 6×)
Material: Steel with ZMAX® G185 galvanized coating for extended corrosion resistance
Gauge: LPC4Z typically 18 ga; LPC6Z typically 16 ga
Installation: Fastens with specified nails; can be installed after the beam is in place
Benefits for Contractors and Homeowners: This light post cap simplifies beam‑to‑post connections with an adjustable, universal design that accommodates variations in jobsite conditions. It eliminates the need to nail directly into end grain, improving structural performance and reducing installation guesswork. The ZMAX® finish helps extend service life in outdoor and treated‑wood environments, delivering durable support and long‑term reliability for deck and outdoor framing connections.
