HONGDUI HD30-YG03 Bench Connector Dog
Flush-Mount Clamping: Unlike traditional bench dogs that protrude significantly above the table surface, the HD30-YG03 utilizes a chamfered lip. It sits completely beneath or flush with the top surface layer, allowing workpieces to slide over it smoothly without obstruction.
Seamless Bench Interconnection: It allows woodworkers to lock two multi-hole tables or sacrificial tops together perfectly. It offers absolute, sub-millimeter registration alignment across a 20mm grid pattern, entirely eliminating the need for measuring or squaring when expanding a workspace.
Jig & Fixture Anchoring: It is ideal for mounting heavy, boxy jigs (such as a Moxon Vise, custom routing templates, or specialized clamping arrays) directly into an existing MFT matrix. Instead of clamping around the edges of the table, the fixture locks rigidly directly from underneath through the dog holes.
Heavy-Duty Expansion Mechanics: Inside the connector dog is an expandable core mechanism. When engaged, it applies internal radial pressure against the walls of the dog hole to guarantee zero lateral wiggle, while simultaneously drawing the top fixture or secondary surface tightly down to the master bench.
Space-Saving Workspace Efficiency: By shifting the clamping mechanism entirely inside the dog holes, it eliminates the clutter of large F-clamps or track clamps on top of the workbench, keeping the production area clean and fully accessible for routers, sanders, and tracksaws.
WARNING! This product can expose you to chemicals, including chromium, which is known to the State of California to cause cancer and birth defects or other reproductive harm.

About HD30-YG03
Engineering the Infinite Workspace: The YG03 System
When expanding your work surface, standard friction dogs allow micro-deflections that ruin long parallel track cuts. The HONGDUI HD30-YG03 reengineers workbench modularity from the ground up, delivering an unyielding structural bridge between separate MFT tops. By utilizing a rigid, mechanical expansion lock inside standard 20mm dog holes, it draws adjacent tables together with intense clamping force. No lipping, no sagging—just one perfectly flat, unified production platform.
