Great value

Would Recommend

I installed these are part of a custom cable railing deck system, and they were perfect for my application. They fit snugly onto the posts, were easy to work with, and feel quite sturdy as part of the complete system. Great value.

Item was received damaged and completely unusable

Would Not Recommend

The post sleeve was cracked lengthwise, all the way through the composite, from top to bottom. I recommend opening the product in-store to verify prior to leaving the store.
