RAM Mounts Stainless Double U-Bolt Rail Base for 1"–1.25" Rails – C-Size 1.5" Ball (RAM-235U)

Two stainless U-bolts through a powder-coated marine-grade aluminium plate. Where a clamp can creep under load, a double U-bolt base is bolted down and stays where you put it — the right choice for a heavy chartplotter or anything that takes a knock.

What’s in the box

• RAM® double U-bolt rail base with C-size 1.5" ball
• Two stainless steel U-bolts and hardware

Base only. You will also need a C-size double socket arm and a C-size cradle or plate.

Fitment

• Rail diameter: 1" – 1.25", round rail only
• Ball size: C Size (1.5") — the arm and cradle must match
• Stainless U-bolts, powder-coated marine-grade aluminium base

This is the range most pontoon top rails fall in — 1" on many factory boats, 1¼" on common aftermarket fence — but measure yours before ordering.

Why buy from Pontoon Outfitters

Delivered free. Most dealers list this a little lower and then add around $8 of shipping, which lands in the same place — we would rather show you the real number up front. Lifetime warranty from RAM®.
