ā€œWorking with Aluglobos has been an absolute game-changer for my business. As a contractor, finding a reliable supplier who truly understands the importance of quality and customer service isn’t easy—but Ronni and Linna make it look effortless. […] The communication is always clear, the turnaround times are impressive, and they genuinely care about building long-term relationships with their clients.ā€

ā€œI’ve been searching for a company that actually makes their material here in the U.S. and uses high-grade aluminum. […] Ronnie was great at explaining the difference in the aluminum they use, and I really liked being able to watch their YouTube videos too. They go really in-depth about the materials and the process which honestly helped me understand what I’m actually paying for.ā€

FAQ

Questions, answered.

Which base plates does it pair with?

Surface-mount options such as the 5Ɨ5 in. base plate for the 3Ɨ3 in. HD post and the base plates for the 2.75 2-way post.

Is it the same as the anchor in the 2Ɨ2 in. gate post kits?

No. Those boxed kits list a 3/8″ x 3″ anchor bolt or hex head wood screw with the base plate; this 3-3/4″ anchor is a separate item.

How many do I need?

Count the anchor holes on each base plate, multiply by the number of posts and add a few spares.

Will this part fit my existing fence or gate?

It is made for Aluglobus systems. Send our team a photo and measurements and we will confirm the right part before you order.

What screws should I use with aluminum?

Use stainless steel fasteners with aluminum to avoid galvanic corrosion.

Full product description: 3/8″ x 3-3/4″ Wedge Anchor

3/8″ x 3-3/4″ Wedge Anchor for Fence Post Base Plates

This 3/8″ x 3-3/4″ wedge anchor is the fastener for securing fence base plates to concrete. Sold individually, it is the listed wedge anchor for fence post base plate installations on slabs, patios and footings, whether you are mounting a new post or replacing a lost anchor.

Base Plates It Pairs With

Our systems include several surface-mount options, such as the 5Ɨ5 in. base plate for the 3Ɨ3 in. HD post and base plates for the 2.75 2-way post. Each is secured to concrete through its anchor holes, and this is the anchor listed for that job.

Planning Your Order

  • Count the anchor holes on each base plate and multiply by the number of posts.
  • Add a few spares for the job.
  • Our boxed 2Ɨ2 in. gate post kits list a 3/8″ x 3″ anchor bolt or hex head wood screw with the base plate; this 3-3/4″ anchor is a separate item.
  • Follow the anchor instructions and local code, and confirm with our team if you are unsure about your concrete.

Base plates are the usual choice when posts go onto an existing slab or patio instead of into a dug footing. Whatever layout you choose, the anchors carry the connection between the post and the concrete, so use the listed anchor, keep the anchor holes on the plate filled, and check the concrete condition before you start. If your post will carry a gate, ask our team to review your post and base plate choice.
