Heavy Duty C-Clamp Mount Compatible with RAM 1in and 1.5in Ball Bases

In this review the Heavy Duty C-Clamp Mount is judged as a practical, no-nonsense mounting solution for anglers and field technicians who need a secure attachment point for electronics. Its biggest selling point is long-term durability: cast aluminum construction with an anti-corrosion coating and composite nylon contact points make it a sensible choice where saltwater, sun, and vibration are concerns. The clamp is best for users who already use RAM B 1" or C 1.5" round ball bases and need a sturdy, adjustable clamp with a wide range of attachment holes.

Key Features

• Compatibility: Works with RAM B 1" and C 1.5" size round ball bases so it integrates easily into existing ball-based mounting systems.
• Durable construction: Cast aluminum body with an anti-corrosion coating protects the clamp and screw from seawater and UV exposure for extended life.
• Secure grip: Composite nylon knobs and nylon blocks increase friction on the screw rod so mounted gear stays put during extended use.
• Multiple mounting holes: Sixteen 5.6mm holes on top and four 6mm holes on the sides allow flexible positioning for different accessories and orientations.
• Wide clamping range: Maximum jaw opening of 3.23 in lets the clamp attach to boat rails, benches, fences, tables and many other surfaces.

Who It's For

This clamp is aimed at boaters, anglers, and technicians who already use round ball mounting systems and need a heavy-duty clamp to secure fish finders, tablets, cameras or other accessories to varied surfaces. The anti-corrosion finish and nylon friction points make it particularly suitable for saltwater use or any environment with exposure to sun and moisture.

Users who need an ultralight or permanently welded mounting solution, or who require a clamping capacity beyond 3.23 in, should consider other mounting styles. Also, anyone not using RAM B or C size ball bases will need an adapter to make this clamp compatible.

Pros & Cons

Pros

• Robust cast aluminum build with anti-corrosion coating enhances longevity in marine environments.
• Designed to work with RAM B 1" and C 1.5" round ball bases for broad accessory compatibility.
• Composite nylon knobs and blocks provide an anti-slip grip for stable long-term mounting.
• Multiple top and side holes give flexible mounting positions for various accessories.

Cons

• Maximum 3.23 in jaw opening limits use on very thick rails or structures without adapters.
• Heavier cast construction may be overkill for ultralight kayak setups.

Frequently Asked Questions

Will this clamp work with my RAM ball mount?
This clamp is designed for compatibility with RAM B 1" and C 1.5" size round ball bases, so it will work directly with those sizes.

Is the clamp corrosion resistant for saltwater use?
Yes, the cast aluminum and the screw have an anti-corrosion coating intended to resist seawater and UV corrosion for longer service life.

How wide a rail can it fit?
The clamp has a maximum jaw opening of 3.23 in, which covers most boat rails, tables, and fences but not very thick structures beyond that range.
