The top rated cord lash hand tool is the ASC390 tensioner. This tensioner is able to pull massive tension. This cord lashing tool is specifically designed for high strength lashing. Run the bottom strap under the gripper and the top strap (coming from buckle) through the front cutter and then the windlass.

Pulling tension is easy; crank the handle, and the strapping wraps around the slotted drum. The long handle lets you pull lots of tension easily! We were able to pull over 3000 pound tension on the lashing when we really leaned into it!

There is an optional cutter on the front of the tool. It is optional because you do not want to accidentally cut your cord strap lashing by pushing the handle too far! Just flip the switch and now you can engage the cutter. We really like this feature; it keeps us from wasting and having to re-strap our bunks! The ASC390 is the best cord lash hand tool out there.
