Marketair Inc. has introduced the RoughinBox RBX-3, a 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 high density, blow-molded, black polyethylene RoughinBox is seamless and waterproof. It expedites minisplit and VRF/VRV evaporator rough-in time by creating a stable central point with dedicated ports for linesets, condensate hose, and electrical/communication cabling to safely and easily enter and terminate.
