What to know before buying

Listing details to confirm

The listing claims the brackets and screws are included, but no separate package inventory is provided. Confirm the selected listing includes the screws and that its fasteners suit your substrate. The description identifies carbon steel with a black powder finish, while the material field specifies 201 Steel. The listing also gives the inner size as both 3.5 x 3.5 inches and 3.5x3.5, so verify dimensions and fit before ordering.

Buyers seeking post bases with pre-drilled holes and a stated 3.5-inch inner opening.

The supplied evidence contains only a very small set of aggregate ratings, all in the highest star category. That is too limited to establish durability, fit or installation experience. For a post base, verify the dimensions and fastener suitability against the actual post and floor rather than relying on ratings.
