- Fits Like a Shield: 4x4 Post Shields are designed to fit the standard 4x4 labeled post. The standard 4x4 post measures 3.5" x 3.5". There are few exceptions, so please measure your post to verify its size before purchasing. New treated posts are often wet and swollen from the treatment process, but they will dry out and shrink to the 3.5" x 3.5" standard post size.
- Snap-On, Stress-Free Install: No screws, drills, or glue—just four interlocking panels that form a solid 4x4 post cover in seconds. This clever tool-free design saves you time while adding clean protection to your porch or fence post. It’s hassle-free DIY at its best.
- Year-Round Weather Armor: Made from durable, UV-stable plastic, these sleeves resist fading, cracking, and warping - rain or shine. Whether you need a mailbox protector or fence post cover, Post Shields stay strong through all four seasons, no touch-ups needed.
- Trimmer-Proof and Tough: Say goodbye to chipped corners and gas trimmer scars. Post Shields guard the most vulnerable part of your post with a tough, low-profile barrier - perfect for decks, fences, and any 4 x 4 post sleeve at risk of lawn equipment damage.
- Protection with Purpose: Born from the need to protect posts without the fuss, Post Shields reflect a simple idea done right. From deck to driveway, our sleeves help you spend less time repairing and more time enjoying your space - because details matter.
