3/8″ aluminum spacer
The 3/8″ aluminum spacer is a small but essential component in modern fencing systems. It provides the precision needed to maintain consistent spacing between fence boards or slats, ensuring your installation looks straight, balanced, and professional.
Whether you’re building a privacy fence, decorative screen, or pool enclosure, using spacers eliminates guesswork and prevents uneven gaps. This results in a fence that not only looks better but also performs longer, as evenly spaced panels distribute stress more effectively.
Homeowners and contractors in Los Angeles, Beverly Hills, Orange County, and nationwide trust our 6063-T6 aluminum spacers for their durability and ease of use. Unlike plastic spacers, which can crack, or steel alternatives, which rust, these aluminum spacers deliver years of reliable service with zero maintenance.
The 3/8 Spacer is a precision-engineered aluminum component that ensures clean, consistent spacing between fence boards or slats in modern fencing systems. Made from high-quality 6063-T6 aluminum, it delivers professional-grade alignment for privacy fences, pool enclosures, and other applications where appearance and stability matter.
Why it works
Maintains consistent, balanced gaps for a modern, professional appearance.
Architectural-grade aluminum built to last decades without degradation.
Unlike steel spacers, it never rusts or corrodes in outdoor conditions.
Handles heat, moisture, and temperature swings without warping or breaking.
No upkeep required – won’t crack, compress, or degrade over time.
Distributes weight evenly across panels, enhancing overall fence stability.
Installation
Position the first fence board or slat in place.
Insert the 3/8 Spacer between boards at the top, middle, and bottom.
Place the next board against the spacer.
Secure both boards with screws or fasteners.
Repeat the process across the entire fence run.
Remove spacers once all boards are securely fastened.
Use multiple 3/8 Spacers vertically for each board connection to ensure perfect alignment throughout.
Aluminum vs plastic vs steel
The 3/8 Spacer outperforms plastic spacers that crack or compress over time, and steel spacers that rust and corrode.

Perfect for contractors seeking consistent results and DIY homeowners wanting flawless spacing, the 3/8 Spacer is the reliable choice for any modern fencing project.
Affordable, but they warp and break under pressure, especially in hot or cold climates.
Strong, but they’re prone to rust and staining, which can damage nearby fence panels.
Lightweight, rust-free, UV-resistant, and perfectly suited for residential, commercial, and coastal projects.
By choosing aluminum, you get the best balance of strength, longevity, and aesthetics.
