Product Overview

The Classy Caps SL4455 PVC adapter fits into the base of compatible Classy Caps models to enlarge the opening from 4 in. x 4 in. to fit an actual 5 in. x 5 in. post.

This adapter is a model-specific fitment part, not a post cap or solar light by itself. Verify the exact Classy Caps cap model and measure the actual post before ordering; a 5 in. x 5 in. nominal description does not confirm compatibility. The adapter should seat fully inside the cap base and fit squarely over the post without rocking or forcing the components. Proper alignment helps the finished cap remain level and keeps a solar model's panel in the correct orientation. Do not use the adapter with unlisted cap models unless compatibility has been confirmed.
