The 3PCS HDCC01B Heavy-Duty Column Clamp is a no-drill mounting solution built for surveyors and field engineers who need fast, stable instrument setup on columns, poles, and overhead beams.

This 3PCS HDCC01B Heavy-Duty Column Clamp features a 6-inch flat platform with a standard 5/8″-11 threaded stud, making it directly compatible with most prisms, total stations, and scanners.

With 12 inches (30 cm) of vertical adjustment and a 15-inch centerline distance, each HDCC01B Heavy-Duty Column Clamp lets you fine-tune instrument height and offset without additional adapters.

The heavy-duty 2″ × 10 ft nylon strap wraps securely around round or square columns, while the structural aluminum body and stainless steel hardware resist corrosion in tunnels, railway environments, and outdoor job sites.

Why Choose Our HDCC01B Heavy-Duty Column Clamp？

① Drill-free installation, protecting structural surfaces: The HDCC01B Heavy-Duty Column Clamp uses heavy-duty nylon straps for fixing, eliminating the need for drilling into columns or beams, making it particularly suitable for tunnels, railway columns, and other scenarios where structural damage is unacceptable.

② High load safety factor: 2,200 lb (1,000 kg) load rating, coupled with 2″ × 10 ft heavy-duty nylon straps, ensures stable operation and prevents displacement under vibration and outdoor environments.

③ Precise adjustment capability: 12″ vertical height adjustment and 15″ centerline distance allow the HDCC01B Heavy-Duty Column Clamp to be quickly aligned even in complex working conditions.

④ Industrial-grade materials: The structural aluminum alloy body combined with stainless steel hardware is corrosion-resistant and wear-resistant, suitable for damp tunnel environments and long-term outdoor use.

⑤ Standard threads, strong compatibility: 5/8″-11 standard threads directly adapt to mainstream prisms, total stations, and scanners, reducing the need for on-site adapters.

⑥ 3-piece set configuration, high cost-effectiveness: One set includes 3 HDCC01B Heavy-Duty Column Clamps, suitable for multi-point simultaneous monitoring and team operations.
