Add a touch of contemporary class to your posts with the Imperial Post Cap Solar Light from Classy Caps. The Imperial Post Cap comes in two sizes to fit perfectly on three sizes of posts: for 4 inch x 4 inch wood posts, use the 3-9/16 inch cap with the included adapter, or take out the adapter to slide the cap over a 4 inch post sleeve; for 5 inch post sleeves, choose the 5-1/32 inch option.

The integrated LED bulb in each cap can stay lit for up to 8 hours, and the durable cast aluminum assembly will retain its color and beauty for years to come.

Effortlessly brighten your deck, porch or walkway with the beautiful, contemporary Imperial Post Cap from Classy Caps.

Unsure about your size? Measure your posts carefully and use our Post Cap Diagram to understand critical dimensions and ensure a proper fit.
