Shur-Lock II

Shur-Lock II

Shur-Lock II is a plastic coupler designed for coupling HDPE & PVC conduit. Can also be used to couple dissimilar conduits such as HDPE to PVC, threaded or non-threaded metal conduit, or fiberglass (FRP) conduit. The coupler features stainless steel band clamps (hand tightened using a 5/16" nut driver) and locking ring. A pre-lubricated O-ring forms an airtight seal to withstand 125 psi. Also a specialized coupler for use by electrical installers requiring ETL/UL listing.
Push-Lock

Push-Lock

Installation is fast and easy; no heat or tools are needed. Simply push the duct ends into the coupler for a locked and air-sealed assembly. The compact profile of the Push-Lock is well suited for use in pull boxes, vaults, or other limited-access areas such as narrow trenches. The non-metallic construction provides excellent corrosion resistance in buried or encased applications and also has desirable dielectric properties. The Push-Lock is non-transparent and contains UV inhibitors, but is not recommend for aerial applications.
End Caps

End Caps

End caps are used as a dust or dirt cover, protecting entry by any foreign objects. They also protect the inner contents from disturbance. Dura-Line offers Flat Vinyl End Caps, Tapered Vinyl End Caps, or Cable End Caps to fit your installation needs.
Cutters

Cutters

Dura-Line offers a variety of cutters for your specific project needs. Choose from: Deburring, Ratchet, Rotary, Slitters, Straight Cutters, and Web Slitters.
Polyester Tape

Polyester Tape

Bull-Line 100% Polyester Pull Tape provides a competitive solution for applications that require a high tensile strength and low elongation. Bull-Line Pull Tape is lightweight and has good blowability. Bull-Line Pull Tape has low burn through resistance in comparison to other brands. An added benefit of all Bull-Line Pull Tapes are the durable print and sequential markings, in both feet or meters, for accurate locating during installation. Bull-Line Pull Tape is made in the USA.
F-100i

F-100i

HydraLube F-100i incorporates new lubricant technology to create a high performance, water-based pourable lubricant formulated for many applications, such as fiber optic, coaxial, 600 V and higher voltage-rated cables. It is designed to meet or exceed all cable pulling requirements with respect to viscosity, cling, drag, wetting, operational temperature range and reduction of pulling tension. Lubricant application systems are available. UL Listed.
AT-500

AT-500

Hydralube® AT-500 is a high performance silicone lubricant formulated specifically for use with compressed air-assisted cable blowing, jetting and pushing systems. These systems inject a high volume of air into the conduit which will rapidly dry out conventional cable placement lubricants (including silicone-based) and cause surface stickiness. Futhermore, the initial temperature of the compressed air can be very high, which will accelerate drying of the lubricant. Hydralube® AT-500 deposits a special low friction silicone coating on the conduit wall surface that is resistant to the drying effects of the rapid air movement and high heat. This product is fully compatible with cable jackets and HDPE or PVC conduit systems.
Lubaduk

Lubaduk

LUBADUK® keeps pull tensions low; up to 74% less friction and 50% less pulling tension than with other lubricants. The effectiveness of LUBADUK® has been proven in the field and with extensive testing. Reduced cable tension (as much as 50%) greatly reduces the wear on cable pulling equipment and improves safety. A unique shear-sensitive carrying agent holds a dispersion of silicone oil and microspheres in suspension. LUBADUK® microspheres are tiny ball bearings, with diameters between 0.010” and 0.020.” Pulling cable with LUBADUK® means cable actually rolls on a layer of microspheres, which keep friction between cable and conduit extremely low. Any change in the cable contact point provides a fresh layer of microspheres, keeping friction low.
