Wanhork Deck-Mount Umbrella Holder White 27.5-inch — 304 Stainless No-Drill Clamp for Railings

Wanhork's 304 stainless steel deck-mount umbrella holder is a rust-resistant, clamp-on post that secures patio umbrellas to railings without drilling.

Designed for balcony, deck, and terrace railings, this white patio umbrella holder provides a heavy-duty, removable way to anchor sun umbrellas. Constructed from corrosion-resistant 304 stainless steel with a durable powder-coated finish, the unit clamps around vertical railing slats and supports umbrella poles between 1" and 1.53" in diameter. The kit ships with a 27.5" tube column, four adjustable stainless clamps, and all fastening hardware for tool-free tightening.

How does this mount attach to my deck railing?

The Wanhork holder clamps onto vertical or picket-style railing grilles using adjustable stainless steel brackets that avoid permanent fasteners. You hand-tighten thumb screws to secure the clamps, so no power tools or drilling are required and the railing surface remains protected.

• Fits vertical railing thickness from 3/4" to 2"
• Adjustable clamp spacing from 2" to 6" between vertical rails
• Hand-tightened plum screws for tool-free installation

Will it fit my umbrella pole and hold it steady?

The tubular post accepts umbrella poles with diameters greater than 1" and less than 1.53", offering a snug, upright mount for common patio umbrellas. The substantial 27.5" column and robust stainless construction deliver stiffness and resistance to bending in typical outdoor conditions.

• Inner tube diameter: 1.53" maximum
• Recommended umbrella pole size: >1" and <1.53"
• Overall length: 27.5" for strong vertical support

How durable is the holder in outdoor environments?

Wanhork uses marine-grade 304 stainless steel and a weatherproof powder coat to protect the mount from moisture and oxidation. Those material choices plus all-stainless fasteners help minimize rusting, so the clamp and tube remain serviceable through seasons of use.

• 304 stainless steel body resists corrosion
• High-temperature powder coating adds weather protection
• All included screws and clamps are stainless steel for long life

What comes in the box and how hard is it to set up?

The package contains one tubular post, four clamp pieces, and all stainless screws and hardware required for assembly. Installation is straightforward: assemble the clamp around your railing, insert the tube, then hand-tighten the plum screws—no special tools needed.

• Included: 1 tube column, 4 clamps, stainless screws and fasteners
• Weight: about 6.28 lb for a stable base
• Installation: step-by-step, hand-tighten assembly
