The RoughinBox RBX-3 now features five lineset entry ports for convenience, and offers bottom and side condensate drain outlets to reduce installation time.

Marketair Incorporated, a supplier of specialized HVAC industry components and accessories, introduces the RoughinBox RBX-3, a versatile redesign of the original RoughinBox for minisplit/VRF/VRV applications.

The RBX-3 now includes an extra lineset port and accommodates both side and bottom drain configurations. The patented RBX-3-MP-NC (Multiple Port-New Construction) is a third generation RoughinBox combining the bottom drain outlet of the RBX-1 and the side outlet of the RBX-2, which offers total installation flexibility for contractors and reduced sku’s for wholesalers.

The additional lineset port brings the total to five (two on top, one on each side, and one on the bottom) which can now accommodate lineset entry from any direction.

The RBX-3 also features four redesigned mounting brackets that are pre notched for use with metal studs, thereby eliminating the need to modify the metal studs during installation, which was a characteristic of the previous models.
