Too small

Bought 4x6 post protectors and they do not quite fit a 4x6 post.
4x6 posts need 5x7 sizes to fully wrap around a 4x6 post.

4x6 Post Shields

Covered My Mount Brackets and screws and looks great

Excellent All Around

Great customer service. Sent me a replacement order after the initial measurements were off. The replacement came quick and fit perfectly. Product was exactly what I was looking for. Highly recommend.

Perfect Fit

Recently poured a slab under an existing pergola. Bottoms of the post were beat up (time and string trimming). Snapped into place for the perfect fit and cleaner look.

Sizes can be deceiving

I bought a 4 x 6 shield. But the width is more like 3 3/4 and the length is more like 5 3/4. The problem is that I actually have a mailbox post that measures exactly 6 x4. So it was a waste of money and I couldn't use it.

Hello John, I'm sorry they did not fit your situation. We do have a notice on the product page for sizing information and a warning to measure before purchasing. Post Shields are designed to fit the standard nominal size posts which can be confusing when dealing with a true to size post like you have. We do have our Custom ClamShells Post Shields which we can make at your required size as a replacement. Contact us at customercare@postshields.com if you'd be interested in that option.
