Otto Winders — Your kites are designed to perform perfectly. Now, so are your line winders.

From a single length of stainless steel,
comes a full range of functions

The rings

Every Otto Winder has two rings. They are sized for hands, so holding them as you wind line feels comfortable and secure.

The rings are positioned to allow pulling the working line through to form a loop. Put the loop over one of the two posts on the Otto Winder and the line is secure.

The winder

The Otto Winder was designed for managing line. It takes in about 16 inches for every figure 8 cycle. Because of the deep shape at the sides, Otto Winders have tremendous capacity.

The posts

By pulling line through one of the rings, and looping it over a post, the line is secured. Instantly cleat the line at any point. It's both easy to form, and quick to release. The other ring and post remain ready to receive loops from line on your anchor.

TriLock path of wire in the Otto Winder - gives it strength and structure against lateral loads

TriLock path

Otto Winders derive a fair measure of their excellent strength from the deceptively simple path of stainless steel at their center.

Formed early in the process, the TriLock prevents deformation under lateral compression. As a result, Otto Winders can support substantial loads.
