Product Description
The Original 4" × 4" Classy Solar Post Cap (PVC) — Optional Adapters
- Classic look — The patented “Original Classy” design with clean lines for vinyl and painted-wood systems.
- Down-wash lighting — Four high-output surface-mount LEDs cast light onto the cap walls and surrounding post.
- Solar-charged battery — Up to all-night accent light after a full charge; automatic dusk-to-dawn.
- Fit — Seats over actual 4" × 4" posts; optional adapters extend compatibility.
- Low maintenance — UV-stable PVC cleans up with simple soap and water.
The Original 4×4 Classy Solar Post Cap is the simple, time-tested way to add wayfinding light and a finished look to standard 4" PVC posts. Its four LEDs are angled to wash the cap’s sides and the adjoining post faces for a cohesive nighttime line without hotspots, while the integrated panel charges a replaceable battery during the day. This is the cap many pros keep on hand for quick upgrades because it installs fast, looks right at home on vinyl systems, and provides reliable accent lighting throughout the season.
If you need to step down to wood 4×4 posts (actual 3.5"), add the dedicated 3.5" × 3.5" Adapter (compatible with SLO74W/SLO78W). For projects that also use premium 6" feature posts, pair this cap with the aluminum Cambridge 6" × 6" Solar Cap to maintain a unified design language at larger columns.
