HEVIDUBANA Pole-to-Pole Mount Stainless Steel Bracket

HEVIDUBANA Heavy Duty Pole to Pole Mount is a stainless steel mast-to-mast bracket kit that securely joins two tubular poles (1"–2.5" OD) for antenna, flagpole, or mast extensions.

This two-set clamp kit is built from 304 stainless steel components to resist corrosion and hold heavy loads outdoors. It lets you fasten a secondary mast to an existing sturdy pole with a controlled stand-off, creating a rigid extension or support point without welding. The hardware includes four alligator-style clamps, two 8" threaded rods and eight flange nuts, providing a complete assembly for typical radio, TV, or flagpole applications.

How does this bracket attach two masts together?

The system uses alligator clamps that grip each tube and two threaded rods that run between the clamps to lock the assembly. As you tighten the flange nuts, the clamps compress around each pole, creating a strong mechanical connection that resists rotation and lateral movement.

• Fits tubing from 1" outside diameter up to 2.5" OD.
• Four heavy-duty alligator clamps secure both poles.
• Two 8" threaded rods link the clamps; eight flange nuts provide fastening and adjustability.

Will this stand up to outdoor weather and corrosion?

All parts are manufactured from 304 stainless steel, chosen for long-term outdoor resistance to rust and oxidation. That makes the kit suitable for permanent rooftop, tower, or yard installations where moisture and seasonal temperature changes occur.

• 304 stainless steel resists corrosion in marine and urban environments.
• Solid metal clamps and heavy hardware reduce fatigue and wear.
• Designed for long-term, low-maintenance outdoor use.

How much stand-off and stability can I expect when mounting a mast to another mast?

The stand-off between masts depends on the existing mast diameter and clamp placement; larger existing poles produce a longer offset. For improved rigidity, it's recommended to use two sets of this bracket spaced along the mast to reduce leverage and sway under load.

• Stand-off varies by existing mast diameter and clamp orientation.
• Use two sets (recommended for extra stability) to minimize bending moment.
• Properly tightened flange nuts and correct clamp alignment maximize stiffness.

What hardware is included and what else might I need?

The package contains four heavy alligator clamps, two 8" threaded rods, and eight flange nuts — enough to assemble one pole-to-pole connection per set and two sets are included. You may need basic hand tools and optional anti-seize or thread locker for long-term reliability.

• Included: 4 alligator clamps, 2 × 8" threaded rods, 8 flange nuts per two-set pack.
• Recommended tools: wrench or socket set, torque wrench, and anti-seize compound.
• For added support, purchase a second HEVIDUBANA set to use two mounting points.

Who is this for: HEVIDUBANA's Heavy Duty Pole to Pole Mount is intended for hobbyists, installers, and property owners who need a robust, corrosion-resistant solution to attach a secondary mast to an existing pole. It's well-suited to amateur radio operators, rooftop antenna installers, flagpole modifiers, and anyone seeking a mechanical, no-weld connection for outdoor poles. If you need a long-lasting bracket that handles 1"–2.5" OD tubing and want the option to add extra stability by installing multiple sets, this kit provides the hardware and materials for a professional-feeling installation.
