BRCOVAN Aluminum Alloy Large Bar Clamp Mount Base with 1.5" TPU Ball — Fits 1.5–2" Rails, Anodized 6061-T6

BRCOVAN's Aluminum Alloy Large Bar Clamp Mount Base pairs a 1.5-inch TPU over-molded swivel ball with a CNC-machined 6061-T6 aluminum body to clamp securely to round rails from 1.5" up to 2" diameter.

This robust clamp mount is built for demanding outdoor and industrial environments where dependable hardware and flexibility matter. The anodized aluminum frame resists corrosion and wear, while the TPU ball delivers friction and protection for attached devices. Four rubber ring inserts let you fine-tune fit on various rail diameters, and the 1.5" ball pattern is compatible with many RAM-style arms and BRCOVAN C-size accessories.

How does the mount accommodate different rail sizes?

The clamp includes four soft rubber ring inserts sized to match common tube diameters so the clamp grips tightly without scratching. Install or remove inserts to expand from a snug 1.5" fit up to a full 2" hole when no insert is used.

• Rubber insert diameters: 1.5" (38.1 mm), 1.65" (41.91 mm), 1.75" (44.45 mm), 1.85" (46.99 mm)
• 2.00" (50.8 mm) mounting hole available when insert removed
• Insert stackability allows precise adjustment for irregular rails

What materials and finishes protect the mount outdoors?

The main body is CNC-machined from 6061-T6 aluminum, chosen for strength-to-weight and corrosion resistance. An iii-grade hard anodized surface finish adds wear resistance and reduces surface oxidation, making it suitable for marine, off-road, and exposed installations.

• 6061-T6 aluminum alloy body for rigidity and low weight
• iii-grade hard anodizing for enhanced abrasion and corrosion resistance
• TPU over-molded ball head for non-slip, wear-resistant contact

Which devices and arm systems are compatible with the 1.5" ball?

The 1.5" TPU ball follows the C-size/1.5-inch swivel ball standard used by RAM-style systems, so it pairs with many double-socket arms and accessory mounts. That makes it a flexible base for electronics, cameras, rod holders, and more when you need a secure swivel joint.

• Compatible with RAM Mounts and BRCOVAN C-size 1.5" double-socket arms
• Works with fish finders, chartplotters, GPS units, tablets, monitors, and cameras using a 1.5" ball pattern
• Pairs with standard double-socket arms for adjustable tilt and rotation

How easy is installation and where can I mount it?

Installation is straightforward and includes an Allen key for tightening the clamp hardware. The clamp is designed to fasten to a wide range of tubular structures common on vehicles and vessels; always measure your rail diameter before ordering to ensure fit.

• Includes Allen key for assembly and tightening
• Fits UTV/ATV roll cages, motorcycle bull bars, roof racks, truck roll bars, kayak rails and more
• Measure rail diameter to select the correct rubber insert or use the 2" hole without inserts

Who is this for? The BRCOVAN Large Bar Clamp Mount Base is aimed at outdoor professionals, marine and off-road enthusiasts, and industrial users who need a rugged, adjustable mounting solution. If you require a corrosion-resistant clamp that adapts to multiple rail sizes and works with common 1.5" ball arms for secure positioning of electronics, cameras, or holders, this mount delivers a practical, serviceable option without unnecessary bulk.
