## Customer Reviews

### ⭐⭐⭐⭐⭐ Excellent solution to our stairway issue
*by B***T on April 12, 2025*

We needed an easy, attractive solution to our indoor stair railing issue. Most post bases are either flange-less (no skirting at the bottom) or all four sides have the flange/skirting. Because of where we needed to set the posts, we needed some skirting but not on all four sides. Tada!! These post bases are ideal for our setup - the size is perfect, our posts fit really well once we screwed everything in, the thick metal is extremely durable, and they are quite attractive. They installed easily and are very sturdy. Highly recommend for deck or stairway installation, indoors or outside.

### ⭐⭐⭐⭐⭐ Very sturdy for putting up wooden posts.
*by M***R on March 10, 2025*

I got these to support my mailbox that has been replaced. They come with all the screws and there are directions. They are well made metal frames and fit tightly around a wooden 4" post. I did have to shave a little off the bottom of the post to make it fit but they work out great. I am using them for the posts holding my mailbox.

### ⭐⭐⭐⭐⭐ Good quality and nice design.
*by N***  on July 11, 2025*

My husband was satisfied with the product and quality.
