What Is a Fly Fishing Hair Stacker?

Fly fishing hair stackers are a useful tool for anglers who are looking to tie their own flies. The stacker is a device that helps create an even, consistent fly pattern when tying a variety of flies. It helps ensure that the desired length and diameter of the hackle is achieved without having to make multiple passes with the hackle pliers.

A fly fishing hair stacker is made up of several components. The first component is the base, which is usually made of metal or plastic.

This piece attaches to the vice and holds the stacker securely in place while tying flies. The next component is the handle, which can be adjusted to allow for greater control when stacking hackles. Additionally, the handle can be used to adjust the tension on the hackle pliers so that they don’t slip while tying.

The next part of a fly fishing hair stacker is the body, which consists of several arms that hold each individual hackle feather in place while it’s being tied into a pattern. The arms are adjustable so that different sizes and lengths of hackles can be held securely in place while tying. Additionally, some models feature an adjustable clamp at the end of each arm so that feathers can be kept in place without slipping out during tying.

Finally, there’s the top section which has two pieces: a removable cover plate and a cover bar. The cover plate sits over the arm section and helps keep everything together when not in use and also prevents dust from getting into your hackles as you work with them. The cover bar allows for easy access to your feathers when you’re ready to tie them into your pattern by simply lifting up on it and exposing all of your feathers for easy handling.


In summary, a fly fishing hair stacker is an essential tool for anglers who want to create consistent patterns when tying their own flies. It consists of several components including a base, handle, body with adjustable arms, removable cover plate, and cover bar which all work together to help ensure an even pattern when tying with hackle feathers.
