    What is the dimensions of the square within the block? Can I put a 4x4 post through the hole?

    Answer This Question

    Hi Brenda, thank you for your question. The openings in a standard 8 in. x 8 in. x 16 in. Concrete Block are approximately 5.5 in. x 5.5 in., although dimensions can vary slightly by manufacturer. Yes, a standard 4x4 post (actual dimensions approximately 3.5 in. x 3.5 in.) will fit through the opening. We recommend verifying the actual block dimensions prior to installation if a precise fit is required. We hope this helps with your project!

      Answer This Question

      Hi Maps, thank you for your question. The **nominal size** of this block is **8 in. x 8 in. x 16 in.**, but the **actual dimensions are approximately 7.625 in. x 7.625 in. x 15.625 in.** This allows room for standard mortar joints, resulting in an 8 in. x 8 in. x 16 in. module when installed. We hope this helps with your project!

        How many blocks for 30linft. By 6 ft high
        ByJul 23, 2026
        1 Answer | 
        Answer This Question

        Hi Wall, thank you for your question. For a wall that is **30 linear feet long and 6 feet high**, you would need approximately **270 standard 8 in. x 8 in. x 16 in. Concrete Blocks**, assuming a single-wythe wall and allowing for standard mortar joints. We recommend purchasing a few extra blocks to account for cuts, waste, and breakage. Be sure to consult local building codes and structural requirements for a wall of this height before construction. We hope this helps with your project!

            Richard, a standard pallet of 8 in. x 8 in. x 16 in. concrete blocks typically contains 90 blocks. Individual blocks generally weigh 30–35 lbs each, so a full pallet will weigh approximately 2,700–3,200 lbs,

                Fence post
                Used to build a fence to keep my dogs off the turf. Overall, they worked out well for this easy project but material does break easily and painting is difficult.

                  Bought this cinder block for a good friends birthday gift. He’s since named her Cindy. She had became his new best friend. She’s loyal, low maintenance, and always there when you need support. Best $2 friendship I’ve ever purchased.

                  I had several concrete locks delivered to my home, and I'm extremely pleased with them! I'm using them as a base for outdoor furniture, and the durability and strength will make my outdoor look last for years! The fact that they can be painted is an added bonus, and their weight makes them sturdy yet light enough for me to move them around if I change how everything is situated. I'm happy with these items! I've had them a couple weeks now and of course they're holding up quite well.

                  Just what I needed. I used these as stands for my beehive. They work perfectly fine.

                  It's a cinder block. It's solid and works as a cinder block should.
