MDF / Laminated Board 18mm Corner Clamp – “Third Hand” Support
This is a simple and practical corner support designed for 18mm MDF and 18mm laminated boards.
It works like a “third hand” – helping you keep panels aligned at 90° during gluing, screwing, or assembly.
🔧 Features:
Designed specifically for 18mm material
Keeps panels square during cabinet or speaker box assembly
Easy to use with standard clamps
Lightweight but strong design
Perfect for MDF, plywood, and laminated boards
🛠 Use Case:
Speaker enclosures

Just slide it over the corner of two panels and secure with clamps. It helps prevent shifting and keeps everything aligned while the glue dries.
