These spacers are designed to speed up installation, reduce the need for measuring with nails, and promote ventilation and drainage. Features include rounded corners and blade-like edges to minimize denting, along with a finger grip for easy insertion and removal.

This set provides 10 spacers in four common thicknesses (1/16″, 1/8″, 3/16″, 1/4″) with a bright blue color for easy visibility on the deck. The “T” shape design helps prevent spacers from rolling away or getting lost, and the color aids in quick identification during installation. The spacers are marketed as a versatile tool for both treated lumber and composite decking, aiming to deliver consistent gaps and alignment across projects while reducing installation time.
Buying Guide — Key Purchase Considerations
- Material and durability: Look for spacers made from rot-resistant plastics like ABS or polypropylene, especially for outdoor use where exposure to moisture and chemicals is common.
- Thickness range: Choose spacers that cover the typical deck spacing sizes you need (1/16″, 1/8″, 3/16″, 1/4″). A set with multiple thicknesses reduces the need for manual re-measurements and adjustments.
- Size and surface area: Larger-diameter spacers can offer greater stability and easier handling on long spans, while smaller spacers may be suitable for tight spaces or intricate deck layouts.
- Visibility and handling: Brightly colored spacers help prevent loss on the job site and speed up spacing decisions, especially when working in low light or on intricate layouts.
- Reuse and compatibility: Ensure spacers can be reused across projects and are compatible with various decking materials (pressure-treated lumber, composite, PVC, hardwood).
- Installation efficiency: Some spacers include design features like finger grips, rounded corners, or “T” shapes to minimize scratches and simplify insertion and removal.
- Storage and organization: Consider sets with clearly labeled sizes to reduce downtime during installation and to keep track of remaining spacers.
- Cost vs. value: While price matters, prioritize durability, set completeness (covering necessary thicknesses), and long-term performance for durable decks.
Across these options, users typically weigh mix-and-match flexibility (multiple sizes in one package) against specialized single-size kits. For large decks with long spans, a 20-pack with several thickness options offers the most versatility. For projects prioritizing quick visual checks, bright colors and clearly labeled spacers save time. When working with ACQ-treated lumber or composite materials, choose spacers with robust resistance to wear and deformation to maintain consistent gaps over repeated use.
