The Trapezoid IC Box 2.0 – Airtight & Nestable

Tripar is pleased to launch the next generation of the Trapezoid IC Box 2.0 with new breakthrough single-piece construction. This IC box is a complete redesign, specifically engineered for airtight performance while reducing costs for OEMs.

The benefits include: 

  • Airtight: Meets the 2 CFM maximum airflow requirements mandated by many state jurisdictions and without requiring caulking or gasketing—a double savings.
  • Nestable design: The IC boxes nest within 1″ of each other, reducing inventory space by 5-7 times. 
  • Single-piece construction: Unlike regular IC boxes, our new design eliminates assembly joints and potential failure points through seamless construction. 
  • Value engineering: Comparable to our Ultra-Airtight (AT) models where you get all the benefits of airtight for a standard price. 
  • Reduced shipping: Because of its nested solution, you can order a year’s worth of IC boxes saving on recurring shipping costs. 
  • Stocked item: Popular sizes of the Trapezoid assemblies will be available for immediate 2-day shipping as volumes pick up.

These Trapezoid IC boxes come without the airtight junction box (part #1281-92-1) installed to permit nesting, so you the OEM only need to pop rivet this on while assembling the rest of your fixtures.

The 6° sloped sides and four small bent tabs1 in each bottom corner prevent nested boxes from wedging together. The sloped sides also enhance serviceability, with improved access & visibility to the inner junction box cover.

To permit nesting, these new boxes have an outward flange2, and remain compatible with the same plaster frames (1286 series) 3 used on our traditional line of IC Boxes.

*No, it’s not an oversight that we do not offer the 178X series Trapezoid IC Boxes in an AT (caulked) version – not needed to meet 2 CFM max airflow with our single piece construction! 

1Tabs contain a small hole (suitable for a #8 self-tapping screw, should you need to affix anything to the box), and are also perforated, allowing OEM to hand bend them out of the way if required.

2Inside length is 1-1/4” less than the traditionally shaped AT IC Box series counterparts.

3Larger Trapezoid box compatible with larger plaster frames (1486 Series) available upon request.

Airtight junction box (part #1281-92-1) and its covers (part #1242-30 and 1242-31) are sold separately.
