Key item features
- Universal Golf Cart & Boat Phone Mount: This versatile phone caddy attaches securely to both square golf cart struts and round boat posts (1" to 5" diameter). Whether you are driving a golf car on the fairway or navigating choppy waters, the adjustable strap system ensures a perfect fit without the need for tools, drilling, or screws.
- Secure Hold on Bumpy Terrain: Engineered to outperform standard cup holder mounts, this holder features a specialized non-slip backing that securely grips vertical rails. It prevents your device from sliding, rotating, or bouncing out, keeping your GPS and scorecard visible and safe even on rough cart paths or in high waves.
- Fits Large Phones & Thick Cases: Designed as a universal cell phone holder for golf carts, the adjustable arms expand from 2.75" to 4.25" wide. It easily accommodates large devices like iPhones and Android phones, and the deep cradle is specifically built to hold phones with thick protective cases without removal.
- Weatherproof & Marine-Grade Durability: Built to withstand the outdoor elements, this mount is made from high-impact, rust-free plastic that resists intense sun, rain, and salt spray. It is the ideal golf cart accessory for men and women who play in all weather, ensuring long-lasting performance compared to metal mounts that may corrode.
- Complete Kit with Bonus Features: Ready to use right out of the box, the package includes the adjustable phone holder, two cinch straps (8" and 12") for different pole sizes, and a non-slip backing pad. It also features a convenient built-in sunglass hanger, providing quick access to your shades and phone in one central location.

Product details
From the Bay to the Back Nine: The Ultimate Hands-Free Solution
Whether you are navigating choppy waters or cruising the fairway, the HoldFastPro keeps your phone secure and accessible. Originally designed to withstand the harsh marine environment, our patented tool-free mounting system is equally effective on golf cart struts. No more rattling in the cup holder or sliding off the seat—get a grip on your device with the mount built for outdoor adventure.
Universal Fit for Phones and Poles
No two boats—and no two phones—are exactly alike. That’s why we designed the HoldFastPro to be universally adaptable.
*Phone Compatibility: The adjustable grip expands from 2.75" to 4.25" wide, easily accommodating standard and plus-sized iPhones and Androids, even with bulky protective cases.
*Pole Compatibility: Mounts securely to any vertical rail or tubing from 1" up to 5" in diameter using our included cinch straps. Perfect for T-tops, grab rails, and center console supports.
Stays Put. Stays Secure.
*A non-slip grip locks the holder in place, a huge part of the holder staying put.
*The deep phone pocket helps prevent your phone from bouncing out in rough waters.
Fits Round & Square Poles
Our industrial-strength hook-and-loop strap system isn't just for T-tops. It adjusts securely to fit square golf cart roof struts (1" - 5"), grab handles, and steering columns.
One-Handed Operation
Speed matters, whether you are checking a GPS chart or a digital scorecard. Our spring-loaded grip allows for easy, one-handed insertion and removal. It fits virtually any smartphone (2.75"–4.25" wide), even those with bulky protective cases.
Weather & Terrain Ready
Engineered with high-impact, rust-free plastic. It handles salt spray on the boat and bumpy terrain on the golf course without slipping. The non-slip backing ensures your GPS scorecard stays visible even on the roughest cart paths.
The "Stealth" Edition for Golfers
While our white mount blends perfectly with marine fiberglass, our Black Edition is designed to match the sleek trim of modern golf carts. Keep your digital scorecard, GPS yardage app, or music playlist at eye level.
Proudly Veteran-Owned & Operated
At HoldFastPro, we understand the importance of gear that doesn't fail when you need it most. As a veteran-owned business, we bring a commitment to integrity and durability to every product we make. We designed this holder to solve a real problem for boaters: keeping expensive electronics safe without permanent installation. Trust HoldFastPro to keep your tech secure on every adventure.
Designed by Offshore Captains
Developed by seasoned offshore ocean captains who navigate in and out of inlets and various offshore sea state.
