RAM® Level Cup 16oz ドリンクホルダー Uボルトベース付き - 0.5" - 1.25" レール対応

The self-leveling cup holder works perfectly on my boat's rails, keeping my drink upright even when I hit some choppy water. The U-bolt base was easy to install and fits my .75-inch rails securely.

The double socket arm gives me tons of adjustment, so I can angle the cup exactly where I need it on my boat's railing without it ever tipping. The self-leveling feature actually works even when I hit some rough chop.

Installed this on my ATV and the self-leveling feature keeps my coffee from spilling even on steep sidehills. The U-bolt base clamped onto my 1-inch rack rail without any adapter needed.
