Product Overview
The LC75-5 Straight Coupler joins two LC75 duct sections end to end. It covers the cut ends and locks the two lengths together so a long run reads as one continuous piece instead of several butted sections.
Use one wherever two straight lengths meet, or where a cut section butts up to a fitting.
