Product Overview
The LC75-1 Decorative Straight Duct is the 2 metre straight section of the LC75 line set cover system — the main run piece that carries refrigerant lines, drain hose and control cable down an exterior wall in one clean trunking.
Cut it to length on site with a saw. Measure the run first, then order enough straight sections to cover it, along with the fittings you need for bends, wall entries and terminations.
