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.

Bolted Rail Clip — M20 Extended

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.

Applications

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.

Primary Use
Medium to heavy crane rail runways where wider lateral adjustment is required during installation
Rail Type
Crane rail A65 to A120 and standard rail 41kg to 53kg
Re-alignment Works
Existing runway installations requiring rail re-alignment without full replacement
Environment
Indoor and outdoor — clip body can be hot-dip galvanized for corrosive environments
Maintenance
Pressure block is replaceable without replacing the full clip top assembly

FAQ

CLX-20 Rail Clip: Common Questions

What is the CLX-20 crane rail clip used for?
The CLX-20 is an M20 through-bolt crane rail clip with an extended lateral adjustment range. It is used for medium to heavy crane rail and standard rail installations where wider lateral adjustment is needed during installation or re-alignment — particularly on existing runways, older structures, or projects with less precise rail positioning during construction.
What is the difference between the CLX-20 and CL4-20?
Both clips use an M20 bolt and function as bearing-type connections, but the CLX-20 has an extended lateral adjustment range compared to the CL4-20. The CL4-20 suits installations with standard alignment tolerances, while the CLX-20 is the better choice where wider lateral adjustment is needed — such as re-alignment works or installations on structures with less precise beam positioning.
What bolt size does the CLX-20 use?
The CLX-20 uses a standard M20 hex bolt with nut and hardened washer, the same bolt size as the CL4-20. For heavier duty applications requiring an M24 bolt with extended adjustment, the CLX-24 is available.
Can the CLX-20 be hot-dip galvanized?
Yes. The CLX-20 clip body and cam can be hot-dip galvanized without reducing the lateral resistance rating of the clip. This makes it suitable for outdoor installations, coastal environments and other applications where corrosion protection is required.
What rail profiles is the CLX-20 compatible with?
The CLX-20 is compatible with medium to heavy crane rail profiles including A65, A75, A100 and A120, as well as standard rail from 41kg to 53kg. If your rail profile is not listed here, send us the details and we'll advise on the right clip.
How do I know if the CLX-20 or CL4-20 is right for my project?
If your installation has standard alignment tolerances and the rail position is well controlled during installation, the CL4-20 will typically suit. If you need wider lateral adjustment — for re-alignment, older structures or more complex installation conditions — the CLX-20 is the better choice. Send us your rail profile, application details and any drawings and we'll advise on the right clip.
