Roof curb
Expansion curb
Designed to eliminate the need for additional structural members for large or heavy roof top air conditioning units. Eliminate costly sub-framing by extending the length of the base curb to match standard framing or joist spacing. Well suited for new or retrofit construction without any addition of support members. For wood, metal, tectum and light weight concrete roof decks. Compatible with traditional built up, one ply membrane, or metal panel roofing systems. Engineered to transfer the concentrated loads of HVAC units and ventilation equipment across several bar joist or purlins. Constructed of heavy gauge galvanized steel with all corners mitered and seams welded watertight.

All options and sizing are available.
