Following right alongside our upgraded L-corner clamps, this is the T-joint version of our multi-size woodworking jigs! Perfect for adding internal shelves, vertical dividers, or cross-bracing to your custom furniture projects using standard 14mm, 16mm, or 19mm MDF and plywood.
This tool slides over the main board and firmly holds your intersecting board at a flawless 90-degree angle. Just like the L-corner version, these T-jigs feature a perfectly positioned rear slot. Once your shelf is clamped in place, you can use the slot as a built-in guide to drill pilot holes perfectly into the center of the board's edge, preventing ugly blowouts and misaligned screws.
Key Features:
3 Essential Sizes: The set includes perfectly toleranced jigs for 14mm, 16mm, and 19mm thick materials.
Center Drill Guides: The outer face features a vertical slot that aligns your drill bit perfectly with the center of the intersecting board.
Clear Labeling: The exact thickness is embossed directly on the jig so you can quickly grab the correct size for your wood.
T-Joint Design: Specifically shaped to clamp intersecting boards securely in the middle of a panel.
Lightweight & Strong: The truss-like top structure uses minimal filament while remaining highly rigid.
