Product Description

The JINQIU CTO-3000-DT-ST-BK Double-Tier Vented Cantilever Offset Patio Umbrella is a robust outdoor shading solution designed to deliver flexible, durable coverage across varied outdoor settings. Its offset cantilever layout suspends the square canopy clear of central support obstructions, anchored by a weighted rectangular base that sits unobtrusively beneath or adjacent to seating arrangements. The structure features 8 powder-coated steel ribs supporting a dual-layer canopy: the main canopy is crafted from solution-dyed polyester, paired with a matching polyester mesh and fabric top vent that enables controlled wind passage to reduce stress on the frame. The supporting structure includes a powder-coated steel vertical pole, curved powder-coated steel support arm, and zinc-plated steel crank and adjustment hardware, with reinforced nylon composite joints connecting ribs to the frame, and an HDPE shell base filled with concrete for stable anchoring. The frame’s 80um powder coating provides consistent surface protection, while the 220 gsm canopy fabric delivers UPF 50+ UV protection and a 1000mm hydrostatic head water repellency rating. Operation is streamlined via a crank handle mounted on the vertical pole for smooth canopy opening and closing. Users can rotate the canopy 360 degrees around the vertical axis, adjust it to a 90-degree vertical tilt, and select from 6 preset height positions, with positive locks securing every tilt and rotation setting. An integrated storage strap secures the canopy when closed, and the double-vent design supports use in wind speeds up to 38 km/h when paired with the recommended 155kg weighted base. This umbrella suits a wide range of spaces, including residential backyards, decks, poolside seating zones, large private balconies and terraces, as well as commercial outdoor areas such as cafe patios, restaurant outdoor dining sections, beer gardens, and garden lounge areas shading lounge chairs or sectional seating sets. When procuring this unit, note that each set ships in 2 cartons, requires 40 minutes of assembly time, and has a packaged gross weight of 120kg. Buyers should ensure the selected base meets the recommended total weighted mass requirement for safe operation, and confirm that installation spaces accommodate the 2200mm under-canopy seated clearance to allow unobstructed use for standard seating configurations.
