Professional T-Track Mini Hold-Down Clamp Kit (71389)
Maximum Clamping Force in a Compact Footprint
The POWERTEC 71389 is a professional-grade 2-pack of Mini T-Track Hold-Down Clamps, specifically precision-engineered for woodworkers and CNC operators who require rock-solid workholding without the bulk of standard clamps. This set is the definitive choice for small-scale fixturing on router tables, drill presses, and assembly jigs. Featuring a specialized lever-shaped profile, these clamps provide optimal downward pressure while maintaining a low height, ensuring your router bit or spindle has maximum clearance to navigate the workpiece surface without interference.
Constructed from premium-grade anodized aluminum, the 71389 set is built to provide industrial-standard durability while remaining lightweight and corrosion-resistant. Each clamp is equipped with non-marring rubber pressure pads that securely grip your stock without denting or damaging delicate wood fibers or pre-finished panels. The included 5/16"-18 T-bolts and ergonomic 5-star knobs allow for rapid, tool-free adjustments in any standard universal T-track or T-slot. Whether you are performing intricate CNC carving or securing a fence on a vertical mill, these mini hold-downs deliver the high-tension stability required for showroom-quality results.
- Low-Profile Design: Compact 3-5/8" length and narrow 3/4" width minimize obstruction of the tool path.
- Non-Marring Grip: Integrated rubber pads provide a high-friction seal while protecting your workpiece finish.
- High-Tension Capacity: Lever-action geometry converts knob torque into massive downward clamping force.
- Anodized Aluminum Build: Heavy-duty metal construction resists flexing and wear in industrial environments.
- Complete Fixturing Kit: Includes (2) clamps, (2) 5/16" T-bolts, (2) washers, and (2) ergonomic 5-star knobs.
