Dura-Line Shur-Lock II Couplers (No Center Stop) are engineered for repairs, retrofits, and tight installations where traditional couplers with center stops can 1t be used. The internal stop is removed, allowing the coupler to slide completely over the conduit end for easy placement in confined areas or when rejoining existing duct runs. These couplers connect HDPE, PVC, metal, and FRP conduit and feature stainless steel band clamps and a pre-lubricated O-ring for an air- and water-tight seal (up to 125 PSI). They are UV resistant, re-enterable, provide high pull-out strength, and are ETL/UL listed for electrical and telecom installations.
