Overview
The 43680 heavy-duty cable lock is designed to help secure trailers, ladders, towing equipment, and other loose or removable items. Built with interwoven 5/16" braided steel and a protective vinyl coating, this 4-foot cable gives you flexible locking reach for common trailer, cargo, and job site security needs.
R&P Service Insight
A cable lock is a practical add-on for trailer owners who need flexible security without relying on one fixed coupler lock style.
- Flexible Use: Helpful for securing trailer couplers, gates, ramps, spare tires, ladder racks, and cargo accessories.
- Surface Protection: The vinyl coating helps reduce scratches on painted, plated, or finished surfaces during normal use.
- Quick Locking: The included keyed lock and two keys make this a ready-to-use security option for shop, yard, trailer, or job site use.
R&P Knowledge Hub
Compatibility: Universal cable-lock style application where a 4 ft cable length and 5/16" cable diameter fit the intended use.
Vehicle / System Fit: Commonly used around trailers, towable equipment, spare tire mounts, ladder racks, cargo boxes, gates, and ramps.
Installation Notes: Route the cable through solid attachment points and verify the cable length is suitable before locking the item in place.
Performance Insight: Braided steel gives the cable strength and flexibility, while the vinyl coating helps protect nearby surfaces during repeated use.
Brand & Fitment Note
Selling Brand: R&P Carriages
Application Reference: This listing is for a universal-style cable lock and is not tied to one specific trailer brand, coupler model, or vehicle platform.
What This Means: Confirm the 4 ft length, 5/16" cable diameter, locking style, and attachment-point clearance before ordering.
Before Ordering: Make sure the cable can pass through the item you need to secure and that the lock body has enough clearance to close properly.
R&P Repair Insight
Cable locks work best when used with secure anchor points and as part of a broader trailer security routine.
- Check Cable Length: A 4 ft cable is useful for many compact locking jobs, but larger items may require more reach.
- Check Anchor Points: Lock only through strong, fixed points that cannot be easily removed or bypassed.
- Check Key Access: Keep one key in a safe backup location so the lock can still be opened if the primary key is misplaced.
