Our caps come in sizes for standard 4×4 and 3.5X3.5 wood and vinyl posts. Just measure the outside of your post and pick the matching size — no tools or adhesive required.

Yes. Each cap is 3D-printed in UV-stabilized PETG, built to withstand rain, snow, and intense sun from -20°F to 140°F without cracking or fading.

Simply press the cap onto a clean, dry post. The snug interior fit holds it firmly in place — most installations take under a minute. There is also a screw hole at the rear of the base for permanent fixture.

Every cap is printed to order in our workshop. Orders typically ship within 3–5 business days.

If a cap doesn't fit or you're not satisfied, contact us within 30 days for an exchange or refund.
