Wiremold Evolution 8AT Series 8 Pre-Pour Poke-Thru Sleeve

The Wiremold Evolution 8AT Series 8 Pre-Pour Poke-Thru Sleeve is a purpose-built, nonmetallic solution designed to streamline electrical routing through structural decking. Engineered for durability and ease of installation, this sleeve maintains a precise 8" to 8 1/8" diameter cast-in hole, delivering a clean, professional finish in both new construction and retrofits. Built to accommodate modern electrical and data needs, the 8AT sleeve integrates seamlessly into decking workflows, reducing on-site cutouts and improving channel protection for cables, conduits, and raceways. With a focus on reliability and accessibility, this poke-thru sleeve simplifies future upgrades, supports code-compliant penetrations, and helps installers achieve consistent results across projects of varying scale.

  • Precise hole maintenance for easier planning: The 8" to 8 1/8" diameter specification ensures a consistent cast-in opening that aligns with standard deck layouts and architectural plans. This precision minimizes rework, speeds up pre-pour stages, and reduces the likelihood of gaps or misalignments once the concrete or decking pours are complete. The sleeve’s tolerance is designed to accommodate typical construction variances while preserving a clean finish for a professional, code-compliant installation.
  • Nonmetallic design for versatile installations: Made from a durable nonmetallic material, this sleeve resists corrosion and does not require special handling around metal framing. Its nonconductive composition helps protect cables and reduces the risk of potential galvanic reactions with other metals in the structure. This flexibility makes it suitable for a wide range of decking materials, including wood and composite decking, while maintaining structural integrity under load.
  • Comprehensive installation kit included: Each unit comes with three attachment legs, two end caps, and three thumb screws. The included hardware provides a secure, fast assembly that holds the sleeve firmly in place during the pour and after curing. The attachment legs distribute the load evenly around the sleeve, while end caps seal the opening to prevent debris intrusion and ensure a neat external appearance once the deck is exposed.
  • Designed for pre-pour efficiency and future flexibility: The Pre-Pour Poke-Thru design supports precise routing of conduit and cables before the decking is poured, enabling a cleaner, more organized installation. The sleeve’s configuration minimizes on-site cutting, reduces noise and dust during installation, and leaves a ready-made pathway that can accommodate additional wiring as needs evolve. This forward-thinking design is ideal for commercial applications, multi-dwelling projects, and frequent reconfiguration scenarios.
  • Durable, installation-friendly performance: The Evolution 8AT sleeve combines robust construction with straightforward handling. Its nonmetallic body resists impact and abrasions during transport and installation, while the three-thumb-screw system facilitates quick mounting and secure retention. The result is a dependable poke-thru solution that maintains hole integrity under decking loads and provides a dependable channel for power, data, and communications infrastructure.

How to install Wiremold Evolution 8AT Series 8 Pre-Pour Poke-Thru Sleeve

  • Plan and verify opening: Confirm the opening size is within the 8" to 8 1/8" range and that the structural decking thickness and material allow for a secure attachment. Review project specifications to ensure compliance with local codes and industry standards for poke-through installations.
  • Position the sleeve: Place the nonmetallic sleeve into the prepared hole location within the decking. Ensure the sleeve sits flush with the deck surface and aligns with the intended cable pathways. If needed, perform a dry fit to verify clearance for conduits and future cable routing.
  • Attach the legs: Install the three attachment legs around the sleeve. Use a light torque to seat them evenly, making sure the legs are oriented to provide balanced support and maximum surface contact with the deck. The legs help distribute loads during the concrete pour and prevent movement after installation.
  • Install end caps: Place the two end caps at the edges of the sleeve to seal the opening and keep debris out during the pour. The end caps create a clean finish and reduce the risk of material ingress that could interfere with cable entry or future maintenance.
  • Secure with thumb screws: Tighten the three thumb screws to secure the sleeve assembly. Ensure the screws are snug and the sleeve remains stable without over-tightening, which could crack the nonmetallic body or distort the sleeve geometry. A secure fit helps preserve the hole integrity and simplifies post-pour cable management.
  • Pour and cure (if applicable): Proceed with the deck pour according to project specifications. After curing, inspect the sleeve for any gaps or misalignments and verify that the hole diameter is preserved. If needed, perform minor cleanup to ensure a clean conduit path for wiring.
  • Final checks and preparation for wiring: Once the deck is ready for electrical installation, verify that the 8" to 8 1/8" hole is clean and unobstructed. Confirm that the sleeve remains securely fastened and that the end caps have not shifted during curing. Prepare to run cables and data lines through the poke-thru with ease.
