The Simpson 1/2 in. x 2-1/4 in. Rod-Coupler Head Sleeve-All Anchor is a pre-assembled, expanding sleeve anchor from Simpson built for dependable load-bearing performance in solid base materials such as concrete and brick. The rod-coupler head design makes this mechanical anchor a practical solution for structural connections that require direct threaded rod attachment, and its zinc-plated carbon steel construction supports use across a wide range of demanding applications - from transportation infrastructure to structural installations requiring third-party-approved anchoring.

Key Features

• Expansion anchor for solid base materials - engineered specifically for concrete, brick, and other solid substrates, delivering consistent, reliable holding power where it matters most
• FM and UL approved with multiple DOT listings - meets rigorous third-party standards for fire-protection, safety-critical, and transportation infrastructure applications, giving you confidence in compliance-sensitive projects
• Rod-coupler head - accepts threaded rod connections directly, making this anchor well-suited for suspended systems, structural tie-ins, and other assemblies requiring rod coupling
• Zinc-plated carbon steel construction - provides a protective finish over durable carbon steel to help resist corrosion in typical interior and sheltered installations
• Pre-assembled design - arrives ready to install with no loose components to manage on the job site, streamlining the anchoring process
• Precise drill bit and wrench sizing - requires a 1/2 in. drill bit and a 5/8 in. wrench, allowing for straightforward tool selection and proper anchor setting every time
• Caution - oversized holes reduce performance - drilling to the correct 1/2 in. diameter is critical, as oversized holes will make it difficult to set the anchor and will reduce the anchor's load capacity

Why This Product

• Approved for the most demanding environments - FM and UL approvals combined with multiple DOT listings mean this sleeve anchor is accepted on fire-protection, safety-critical, and highway construction projects where certification requirements are non-negotiable
• Purpose-built for threaded rod connections - the rod-coupler head style addresses a specific structural need, eliminating the need for additional hardware or adapters when attaching threaded rod in concrete anchoring applications
• Trusted brand with broad application coverage - Simpson mechanical anchors are designed to perform across complex infrastructure and everyday construction scenarios, making this a dependable choice whether the project is large-scale or straightforward
• Consistent, verifiable installation - defined tool requirements and a pre-assembled sleeve ensure repeatable results, reducing guesswork and installation variability on the job site
