Masonry Mortar Joint Spacers: 500-Pack at $100 vs 100-Pack at $20

Need even mortar joints for a DIY brick mailbox or block wall? Compare a 500-piece spacer bundle at $100 with a 100-piece lot at $20, both made in the USA.

Last updated Aug 17, 2026

When you're working with cement, concrete, or masonry, consistent mortar joints make a big difference in how straight and clean your brick or block work looks. Two masonry mortar joint spacer sets present a clear trade-off: one comes with a large supply, the other with a smaller supply. The right pick depends on the size of your project and how much you want to spend upfront. A bulk set can keep you from running out mid-project, while a smaller set keeps the initial investment light and lets you buy more only if you need it.

Quick Verdict

For a big wall or multiple DIY jobs, the bulk option is the practical buy. For a single brick mailbox, the smaller option is the lighter upfront spend. Both spacer sets are designed to help you lay brick and block with even joints, so your choice mostly comes down to scale and budget.

Where Each Product Wins

  • The larger set wins for big jobs because it includes a substantial quantity of spacers, so you won't run short on a long wall or multi-step project. With a large supply, you can keep one portion at your work area and store the rest.
  • The smaller set wins for small, single-purpose projects because the initial cost is lower and you're not overbuying. It's easier to store and a lighter commitment if you're new to masonry.

500 MASONRY MORTAR JOINT SPACER'S for DIY Block & Bricklaying

This bundle includes 500 spacers in 25 packs of 20, giving you a large quantity for a substantial block or brick project. At USD 100.00, it's the higher upfront price, but the volume means you won't need a second order for a big wall or multiple jobs. It's designed for the handyman, homeowner, and do-it-yourselfer, and it's made in the United States. The condition is new, and it's not a custom bundle or modified item. The trade-off is the $100 commitment before you start laying. If you're planning a large patio, retaining wall, or several projects around the house, having 500 spacers in hand means fewer interruptions.

MASONRY MORTAR JOINT SPACER'S for DIY Brick Mailbox easy cinder block laying

This set includes 100 spacers, each sized at 3/8\" x 4\" for standard mortar joints. It's made for DIY projects like a brick mailbox or cinder block work, and a typical build might need around 200 pieces, with one spacer per block as a common guide. The brand is Block and Brick Spacer, it's new, and it's made in the United States. At USD 20.00, it's the lower upfront cost, but you may need to buy additional lots if the project grows beyond a single mailbox or small wall. If you're just getting started and don't want to invest $100 before your first block is laid, this smaller lot is a measured entry point.

Final Choice by Use Case

  • For a large project, choose the MASONRY MORTAR JOINT SPACER'S for DIY Block & Bricklaying. It gives you the volume you need for a big wall or multiple jobs, and the higher upfront price buys a lot of convenience.
  • For a one-time brick mailbox, the MASONRY MORTAR JOINT SPACER'S for DIY Brick Mailbox easy cinder block laying is the leaner pick, with a lower upfront cost and a size that matches a typical mailbox project.
