CLX-20 Bolted Rail Clip (M20)
Through-bolt crane rail clip with M20 bolt and extended lateral adjustment range. Bearing-type connection suited to crane rail and standard rail installations where wider alignment tolerance is required.
CLX-20 Through-Bolt Crane Rail Clip
The CLX-20 is an M20 through-bolt crane rail clip designed as a bearing-type connection with an extended lateral adjustment range. It uses a circular cam mechanism to lock the clip body against the rail foot, providing secure lateral restraint while allowing future adjustment or rail replacement.
The key difference between the CLX-20 and the CL4-20 is the extended lateral adjustment range. This makes the CLX-20 the preferred choice for installations where rail alignment tolerances are wider — such as re-alignment works on existing runways, installations on older structures, or projects where precise rail positioning during installation is required.
The clip body and cam can be hot-dip galvanized without reducing lateral resistance ratings. The clip top incorporates a vulcanized synthetic pressure block for rail retention and load absorption. The modular pressure block can be replaced without replacing the entire clip top assembly.

Rail Profiles the CLX-20 Suits
The CLX-20 is compatible with medium to heavy crane rail profiles and a wide range of standard rail. Its extended adjustment range makes it particularly useful where alignment precision during installation is important. Not sure if the CLX-20 or CL4-20 is right for your project?

Where the CLX-20 is Used
The CLX-20 is preferred over the CL4-20 where wider lateral adjustment is needed during installation or re-alignment. It suits medium to heavy crane rail and standard rail installations where alignment flexibility is a project requirement.
