Large Tough-Claw Clamp Mount Base — 1.5" Ball, Fits 30–70mm Bars, White Powder-Coated Aluminium (RAM Compatible)

The big sibling to the standard tough-claw — this large clamp swallows bars and poles from 30 to 70 mm in diameter, where the smaller version (26–53 mm) taps out. Same one-knob, no-drill clamp design, just a much wider jaw for the fatter pipes you actually run into in the real world: marine railings, T-tops, awning poles, scaffolding, wheelchair frames, RV exterior bars and roll cages with the bigger tube.

White powder-coated finish to match our other “medical white” Modular Mount System components — built for marine cabins, healthcare carts, ambulance and patient transport, and any environment where a chunky black clamp would look out of place. Drops a 1.5” (38.1 mm / RAM B-size) ball straight onto whatever bar you’re working with, no tools, no drilling, no permanent mods.

Why we picked it

• Wide 30–70 mm jaw — clamps round, square and irregular bars that the standard tough-claw can’t fit
• Marine-grade aluminium & tough nylon body — light, strong, salt-resistant
• White powder coat — UV stable, anti-corrosion, blends with white interiors
• Single-knob clamp — hand-tighten, no tools, no drill holes, fully reversible
• 1.5” (RAM B-size) ball — works with any standard B-size socket arm, ours or third-party
• Rubber-cushioned jaw — non-slip and protects whatever bar you clamp it to

Specifications

Where it fits

• Marine — helm rails, T-top frames, bimini bars, fishing rod holders — the white finish disappears against painted hardtops and railings
• Wheelchair & healthcare — tablet and scanner holders on wheelchair frames, IV poles, medical cart uprights
• Caravan & RV — awning poles, exterior grab rails, ladder uprights, tow-mirror arms
• Workshops & sites — scaffolding, racking, cage bars, roll cages on UTVs and side-by-sides
• Anywhere the standard tough-claw is too small for the bar and you don’t want to drill

Bigger sibling to the standard tough-claw

If your bar measures up to 53 mm and you want the smaller, lighter clamp, the standard tough-claw in the Modular Mount System collection is the right pick. This large version takes over from there — 30 mm minimum (so it overlaps with the standard at the small end), 70 mm maximum at the big end. If you’re unsure which size you need, measure the bar diameter first.
