4" Low Profile Sliding Winch
The US Cargo Control 421 is a four-inch low profile sliding winch built for bottom-mount installation. It belongs to the lifting, pulling and conveying category and is intended for securing heavy loads on trailers or flatbeds. The unit ships new directly from the manufacturer.
Suited for bottom-mount tie-down points
This winch suits operators who need a low-profile unit that mounts underneath the trailer frame. It is not for users who require a side-mount or weld-on configuration, nor for applications that demand a ratchet-style tensioner instead of a sliding mechanism. Buyers needing a different mount pattern should look at other models.
Behaviour under sustained load
The sliding mechanism maintains tension continuously while the vehicle is in motion, reducing the need for frequent re-tightening. The low-profile design keeps the winch below the deck surface, limiting snag risk during loading and unloading. Orders of 75 dollars or more ship free from the manufacturer.

Questions about this item
What strap width does the 4" low-profile sliding winch accept?
The winch is built for 4-inch webbing, so any strap of that width will seat correctly in the drum.
Can the bottom-mount base bolt to an existing trailer frame without extra brackets?
Yes — the bottom-mount design bolts directly to a flat frame surface using standard hardware.
How do I confirm the sliding mechanism moves freely after installation?
Pull the release lever; the winch should slide smoothly along the track and lock solidly in each detent.
