The Pipe Clamp #21 creates strong 90-degree side-outlet tee connections and is often paired with Pipe Clamp #20 to form corner joints for middle rails and rectangular structures. It works well in playground builds, railings, frames, fencing, work tables, and other commercial or educational installations. Because the upright pipe passes through the fitting, it provides added stability and clean vertical alignment.
In addition, its slide-on design and simple set-screw fastener allow quick, no-weld installation. As a result, this clamp is suitable for angled framing, layout reinforcement, modifications, and routine maintenance in playgrounds, daycares, therapy spaces, and community environments.
