We are pleased to introduce an updated design to our proven lines of galvanized IC Boxes: available in both Chicago Plenum and Ultra Airtight versions.
Made of .027” min thickness steel to comply with UL1598, the benefits are:
- Increased inside height: With two side panels replacing the double ceiling construction of its predecessor, these maintain the same outside dimensions while offering an additional ½” inside height.
- Improved heat dissipation: With single-ceiling box construction (instead of two), heat dissipates easier. For even greater heat dissipation, check our our Black IC Boxes.
Both the existing Double ceiling and new Single Ceiling IC Boxes will remain available. However certain versions of these new Single Ceiling IC Boxes will be stocked by Tripar, resulting in better pricing and shorter lead times.
