Product Description

Kingsbridge Cast Aluminum Dual Solar Post Cap — Fits 4 Sizes

• One-cap-fits-four — Patent-pending design fits 3.5"×3.5", 4"×4", 5"×5", 5.5"×5.5" posts (adapters included).
• Dual lighting effect — Real pebbled-glass lens and strategically placed LEDs for dramatic accents.
• Premium materials — Cast aluminum body with monocrystalline solar panel for efficient charging.
• Long-life battery — 3.2V LiFePO4 rechargeable cell supports many seasons of nightly use.
• Zero wiring — Solar-charged battery powers dusk-to-dawn operation automatically.

Kingsbridge is Classy Caps’ flagship “one cap fits all” solution when your project mixes multiple post sizes. The cast aluminum housing and pebbled-glass lens create a rich, high-end look by day and a standout lighting statement after dark. Under the hood, a monocrystalline panel and LiFePO4 battery deliver efficient charging and reliable cycles through the seasons, so you can specify Kingsbridge confidently on feature locations like driveway entries, stair landings, and corner columns. Its multi-fit base covers four of the most common square post sizes with adapters in the box — ideal for retrofits and phased projects.

Lay out lighting at key architectural points first, then extend along rails as needed for continuity. For aluminum 6"-class posts elsewhere on the project, the low-profile Cambridge 6"×6" Solar Cap keeps the premium look consistent. If you need a cost-effective companion on standard 4" vinyl sections, add a classic option like White PVC Pyramid Solar Caps to balance budget and style.
