كرة RAM® Tough-Ball™ مع مسمار ملولب 1/4-20 × 0.50 بوصة للقوارب - مقاس C

The rubber ball grips my kayak mount perfectly — no slipping even on choppy water. That threaded stud lined up exactly with my existing hardware, making installation a breeze.

Installed this on my kayak with the pre-drilled 1/4"-20 threaded hole and it locked down tight with the included washer—no wobble at all so far. The 1.5" rubber ball holds my electronics cradle securely even when I paddle through some choppy water.

The 1.5-inch rubber ball grips my kayak's mounting track perfectly, and that threaded post with the tooth lock washer hasn't budged through three rough outings. Solid, simple, and exactly what I needed for my phone mount.
