Description
The Cablecraft 3000 lb Pull-Only Brake Control Cable Assembly provides a flexible alternative to rigid mechanical linkage in demanding brake and actuation systems. It is engineered to transfer pull motion between two mechanical devices while supporting high tensile loads and minimizing deflection.
The 3000 Series uses a larger 1×37 steel-strand innermember and heavier conduit construction than the 1500 Series. This makes it appropriate for higher-load pull-only systems where durability, repeatable force transfer, and reliable mechanical actuation are critical.
A plastic liner supports smooth operation within the conduit, while the nylon-covered innermember and internal conduit-cap seals provide protection within the assembly. The cable can be routed through equipment using a minimum bend radius of 7 inches.

Engineered and Configured for the Installation
The 3000 Series can be configured around the exact requirements of the customer’s system. Cablecraft can tailor both cable dimensions and connection hardware to fit an existing design, replacement application, or new OEM assembly.
Available configuration choices include:
- Custom conduit length
- Custom innermember length
- Application-specific cable travel
- Threaded conduit ends
- Grooved conduit ends
- Clip-lock fittings
- Threaded innermember fittings
- Ball ends
- Eye ends
- Cable stops
- Open strap clevises
- Step strap clevises
- Closed strap clevises
- Rod ends
- Removable hardware
- Application-specific fitting combinations
Custom changes can be reviewed to match mounting geometry, connection points, load requirements, and available installation space.

The 3000 Series drawing specifies a 3,000 lb ultimate load, 7-inch minimum bend radius, 0.187-inch 1×37 steel-strand innermember, nylon covering, approximately 0.59-inch conduit diameter, and internal conduit-cap seals.
Load Selection Note
The 3,000 lb rating is the ultimate load, not the recommended working load for every installation. The working load and required safety factor must be determined based on the application, routing, number of bends, environmental conditions, duty cycle, and consequences of failure.

FAQ’s
What is a 3000 lb pull-only brake control cable?
It is a flexible mechanical control cable designed to transmit pulling force between two mechanical devices. The Cablecraft 3000 Series has a 3,000 lb ultimate load and is intended for demanding brake and pull-only actuation systems.
Is the cable rated to work continuously at 3,000 lb?
The 3,000 lb value is the ultimate load, not a universal continuous working-load rating. A suitable working load and safety factor must be established for the specific system.
What is the minimum bend radius of the 3000 Series?
The minimum bend radius is 7 inches. The cable should be routed at or above this radius and should not be kinked or forced through a tighter path.
How does the 3000 Series differ from the 1500 Series?
The 3000 Series provides a higher ultimate load, uses a larger 0.187-inch 1×37 steel-strand innermember, has a larger conduit, and requires a 7-inch minimum bend radius. The 1500 Series has a 1,500 lb ultimate load and a 5-inch minimum bend radius.
Can Cablecraft modify the cable for a custom system?
Yes. Length, travel, conduit ends, innermember ends, clevises, threaded fittings, ball ends, eye ends, cable stops, rod ends, and other connection details can be configured for a custom-tailored solution.
Can different fittings be used on each end?
Yes. The left and right conduit fittings and innermember fittings are specified independently, allowing the cable to connect two different mounting arrangements.
What should be submitted with a quote request?
Provide the maximum operating load, desired safety factor, conduit length, overall cable length, required travel, fitting details, routing, bend radius, environmental exposure, expected duty cycle, quantity, and any available drawings or photos.
