What it does

Holds 1/4, 3/8, and 1/2 inch socket extensions
Mounts on standard pegboards with regular hooks
Frees drawer space for sockets and torque tools
Brings tidy extension storage to any tool wall

Stop digging for the right extension. This pegboard holder lines up your 1/4 inch, 3/8 inch, and 1/2 inch socket extensions in their own slots, so the right length stays visible at a glance. Reach, grab, work.

The holder mounts on standard pegboards using common hooks, so adding it to an existing tool wall takes minutes. Designed around Mastercraft-style extensions, but it fits most common brands. Print extra holders to handle deep collections.

Built for mechanics, hobby tinkerers, and anyone with a busy socket drawer. The kind of small storage that turns chaos into calm.
