RAM MOUNTS Quick-Grip XL Phone Holder — B-size 1" Ball Mount, spring-loaded clamp, marine-grade durability

The RAM MOUNTS Quick-Grip XL Phone Holder is a spring-loaded, heavy-duty cradle with an included B-size 1" rubber ball that secures large smartphones and devices while offering virtually unlimited adjustability.

Built for demanding environments where stability matters, this Quick-Grip XL combines a spring-loaded clamp with adjustable side supports and a standard B-size 1" RAM rubber ball so you can attach the holder to any compatible RAM double-socket arm. Constructed from powder-coated marine-grade aluminum and reinforced composite materials, the mount resists corrosion and stands up to vibration, salt air, and road shock. It fits many of today's larger phones and small tablets, keeping the device accessible without blocking critical ports or buttons.

How does this holder keep large phones secure while still letting me remove the device easily?

The Quick-Grip XL uses a spring-loaded mechanism that holds the phone snugly between adjustable side supports. The spring provides firm grip under vibration while allowing one-handed insertion and removal so you can dock or undock quickly.

• Spring-loaded clamp for fast one-hand operation
• Adjustable side supports accommodate different phone widths
• Max depth 0.72" protects against slipping while keeping ports accessible
