Shur-Lock II Coupler | No Center Stop | For Repairs & Tight Installs

Shur-Lock II Coupler | No Center Stop (NS) | For Repairs & Tight Installs

Dura-Line Shur-Lock II Couplers (No Center Stop) are engineered for repairs, retrofits, and tight installations where traditional couplers with center stops can’t 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.

Built for versatility, these couplers connect HDPE, PVC, metal, and fiberglass (FRP) conduit with exceptional mechanical strength and sealing integrity. Each coupler features stainless steel band clamps and a locking ring that tighten easily using a 5/16" nut driver—no special tools required. A pre-lubricated O-ring provides a dependable, air- and water-tight seal up to 125 PSI.

With high pull-out strength, UV resistance, and re-enterable design, the Shur-Lock II (NS) is ideal for both underground and above-grade applications. These couplers are ETL and UL listed for electrical and telecom installations, ensuring long-term reliability in demanding environments.
