  • CHECK THE SIZE BEFORE PURCHASING--Use it when post doesn't swell. Please make sure to use it for dry wood post with post size ≤ 3.5in, the base will fit tightly to the post. Please DO NOT use it on posts that have swelled after rain, humid conditions or high temperatures, as the posts may be too large to fit in.
  • CORROSION RESISTANCE & HEAVY DUTY--The 4x4 post anchor base kit is made of 2mm thick premium solid anti-deformation carbon steel and coated with black powder for durability against corrosion, rust, and abrasion. 4x4 deck post base ensures long-lasting use, lowers maintenance costs, offers reliable support, and remains intact in storms, rain, snow, and harsh weather.
  • WIDELY USED--For small base areas, from deck construction to fence building. Can be used for 4x4 metal, plastic and wood posts, can be painted in your desired color. The 4x4 post base for concrete can be installed on concrete and wooden floors. The deck post bracket is a perfect decoration for doorways, gardens, courtyards, porches, etc. It provides strong support and timber protection for porch railings, decking handrails, fences, pergolas, benches, signs, columns, and mailbox posts.
  • STABLE CONSTRUCTION & UNIQUE DESIGN--The 4x4 post brackets for wood are completely hollowed ensuring full ground contact for stable support and effective water drainage, preventing long-term wood rot. The enlarged 6x6 in base provides greater stability. Its sleek black finish and curved design offer a more decorative and textured look than standard post bases.
  • EASY TO INSTALL & LOW MAINTAIN--Each 4x4 anchor post base has four holes on the bottom and eight holes on the top for a stronger fixing, so you only need to tighten the self-tapping screws to install it on the wooden deck. If using on concrete, drill holes in the ground and tap in expansion screws before installing self-tapping screws.

These brackets are strong and the 4X4 has a nice fit in them which would make them easy to calk the post in and keep water out. There are plenty of holes to solidly mount them to the deck and mount the post to them solidly. I look forward to using them this spring.

I got these post bases to support posts for a new railing for our front porch. The quality is very good, made of thick metal with a generous coat of powder coating. Installation was very simple, just screw them in place! They look really nice and professional.They have pretty tight tolerances, providing a snug fit. I originally fit-tested then on an old 4x4 post outside, and they did not fit over the end of the post. However, they fit fine over new 4x4 posts. The old one has been outside in the elements for years, and has slightly expanded as a result.
