Copper-free aluminum housing provides corrosion resistance and lighter handling, reducing maintenance costs and downtime in damp or outdoor environments. This translates to longer service life for expansion couplings in harsh conditions and easier installation with standard tools and supports. The design supports up to 4 inches of conduit movement and a 4" trade size, accommodating thermal expansion, seismic movement, and vibration without compromising seal integrity or conduit alignment. With a 9.81 in length and a compact 6.62 in footprint, installation fits within typical pull boxes and enclosures, improving project timelines and reducing field modifications. The unit is specified for Ordinary/Non-Hazardous Locations, aligning with NEC/CEC compliance and simplifying regulatory documentation for facilities and contractors. Reference catalogs and installation sheets ensure proper cross-reference and quick material validation, accelerating procurement and reducing misfit risk.
