Weaver Throw Line Cube

The Weaver throw line cube is a square throw line container that holds its shape on the ground, so you can stuff line in quickly and throw again without tangles. It is one of the most common ways climbers keep throw line under control.

Why throw line needs its own storage

A throw cube sits on the ground like an open box. Between throws you feed the line straight in by the handful, and when you throw again it lifts off the top without snagging. That simple shape is why the cube is a favorite for climbers who set a lot of lines in a day.

Thin throw line tangles faster than anything else in the truck. A loose pile turns into a bird's nest the moment you try to throw from it, and untangling it eats time at the start of every job. Keeping the line in a container that opens wide and lets it flake out cleanly is the easiest fix. Compare options in our gear storage section.

Throwing from it and caring for it

Feed the line in loosely rather than wrapping it, and keep the end tied off inside so it cannot be pulled away. Set the bag on the ground a step back from where you throw so the line peels off the top without catching your feet or brush.

Keep throw line dry and out of the sun between jobs, and away from fuel and bar oil. Before setting a climbing line, check the throw line and weight for cuts or damage, and keep the area under the throw clear of people.

If the cube gets packed with sawdust or leaves, turn it out and shake it clean. Debris in the bag ends up wrapped in the line and makes every throw less predictable.
