Short Double Socket Arm — 87mm, 1.5" Ball, White Powder-Coated Aluminium (RAM Compatible)

The 87mm short double socket arm is the compact bridge in the 1.5" C-size mount system. When you need a tight install — a screen pinned close to the dash, a tablet against a yacht console, or a phone tucked beside the windscreen — the short arm keeps everything rigid and out of the way.

Finished in medical-grade white powder coat over marine-grade aluminium, it suits clean interiors that need to look as good as they perform: white-trim caravans, RVs, motor cruisers and yachts, medical and dental rigs, and clean-industrial workshops where matte black would clash.

What you get

• Length: 87mm (3.4") socket-to-socket — the short option in the 1.5" C-series
• Material: marine-grade aluminium, white powder coat (anti-corrosion, UV-stable)
• Sockets: twin 1.5" C-size cups, RAM™ B-Size pattern compatible
• Adjustment: 360° horizontal, 180° vertical at each ball
• Locking knob: oversized white T-handle — tighten by hand, no tools
• Includes: short arm + locking knob + spring

Where it earns its keep

• Yachts and motor cruisers — matches gelcoat and white interiors
• Caravans, motorhomes and slide-on campers with white cabinetry
• Dash-mount tablets, GPS units and fish finders that need to sit close to the helm
• Medical, dental and clean-room equipment carts where stainless and white are the norm
• Roof-rack and bull-bar accessories that need to bridge two 1.5" balls without adding length

Pairs with

Use this arm with any 1.5" (C-size) ball base or device adapter from the Modular Mount System. White ball bases pair cleanly for an all-white build; black bases work too if you want a two-tone look.

If you need more reach, the 150mm long version of this arm is also available in white through the same collection.

Care

Wipe with a damp cloth. Powder coat is salt-spray and UV resistant — safe for marine environments. Avoid solvents that strip paint.
