JINHAN Stainless Steel Patio Umbrella Clamp — 360° Rotatable Railing Holder, Rubber‑Padded Jaws

The JINHAN Stainless Steel Patio Umbrella Clamp is a heavy-duty, 360° rotatable railing holder that secures most umbrellas to fences, bleachers, tailgates and decks for adjustable shade anywhere.

Lightweight to carry yet built for harsh conditions, this umbrella clamp provides a stable, tool-free way to mount an umbrella where a fixed stand won’t work. Constructed from thick-gauge stainless steel with rubber-padded jaws and upgraded gears, it resists rust and keeps your canopy steady on boats, patios, at sporting events, or on the go. The clamp fits tubes up to 1.57" inner diameter and grips surfaces up to 4 5/8" thick, while offering more than twenty horizontal and vertical positions plus a tilt for precise sun control.

How does the clamp hold an umbrella securely on uneven surfaces?

The JINHAN clamp uses a combination of double thumbscrews, rubber-padded jaws and stainless-steel gears to lock the umbrella pole and clamp body in place. The padded jaws conform to railing edges without scratching, while the thumbscrews let you increase tension for a firmer grip.

• double thumbscrews for tight locking
• rubber-padded jaws protect and stabilize surfaces
• solid stainless-steel gears prevent slipping under load
• max clamp opening accommodates 4 5/8" thick railings

What range of motion and angle control does the holder provide?

Designed for flexible shade positioning, the holder rotates a full 360° and tilts so you can block low sun at sunrise or sunset. It adjusts horizontally and vertically into more than twenty preset positions so you can fine-tune coverage without moving the clamp.

• 360° rotation for any sun direction
• tilt mechanism for low-angle sunlight
• over twenty positioning options for precise coverage
• quick-release adjustments for fast changes

Which umbrellas and mounting locations are compatible?

The clamp is built to be universally compatible with most umbrella poles under 1 9/16" outer diameter and fits a wide variety of mounting surfaces. It works on bleacher rails, balcony balustrades, boat rails, tailgate edges, fences, benches and many deck posts—making it a versatile shade solution for travel and outdoor events.

• fits umbrella poles less than 1 9/16" outer diameter

Is it easy to carry and set up when traveling?
