Vashly Heavy Duty Suction Cup Anchors 4-Pack — 3.55" Cups, 70 lb Capacity with Hooks & Tarp Clips

The Vashly Heavy Duty Suction Cup Anchor set includes four strong 3.55" suction cups with detachable hook straps and four rotating tarp clips, each rated to support heavy loads up to 70 pounds on smooth, non-porous surfaces.

If you need a temporary tie-down solution that won’t drill holes or leave marks, this kit pairs oversized suction cups with robust nylon straps and crocodile-grip tarp clamps to secure awnings, tarps, cargo, or accessories to glass, metal, tile, or painted surfaces. The components are designed for repeated use: the large-diameter cups increase bearing capacity, the straps detach for versatile mounting, and the tarp clips lock around fabric edges of varying thickness.

How much weight can each suction cup safely carry?

Each large suction cup is engineered to hold substantial weight for short- to medium-term applications when applied correctly to clean, flat surfaces. The wider 3.55-inch cup base increases suction area and stability compared with smaller models.

• Rated capacity up to approximately 70 pounds when mounted on ideal smooth surfaces
• Larger 9 cm (3.55 in) diameter provides stronger vacuum force
• Best performance on glass, metal, tile, and smooth painted panels

What materials and construction improve durability?

The anchors combine resilient plastics and flexible sealing compounds so they stand up to repeated attachment and removal. Strap and clip components are selected for toughness and resistance to tearing.

• Cup base made from PP/TPU for flexible sealing and washability
• Hook and body components molded in ABS and PVC for impact resistance
• Nylon straps resist abrasion while remaining lightweight

How do I restore suction if a cup loses stickiness?

Restore suction quickly without special tools by rinsing and reconditioning the cup surface. Avoid soaps and oily solvents that leave residue and reduce adhesion.

• Rinse the rubber cup with plain water and gently massage to remove dust
• Air dry or blot with lint-free cloth; do not expose to strong solvents
• Reattach to a spotless, dry surface and press firmly to remove trapped air

Where is this kit best used and how does the tarp clip help?

The set excels where temporary, non-damaging anchor points are needed—on vehicles, windows, boats, and hard-surfaced walls. The tarp clip's tooth-like profile and rotatable lock accommodate different fabric thicknesses and help prevent slippage.

• Tarp clamps hold canvas, polyethylene tarps, and similar materials securely
• Rotating lock adjusts to fabric thickness and maintains grip under tension
• No drilling required—safe for rented vehicles or temporary setups

Who is this for? This Vashly suction cup anchor and tarp clip kit is aimed at DIYers, campers, boaters, market stall operators, and vehicle owners who want strong, reusable tie-down points without permanent hardware. It’s especially useful when you need quick installation, versatile attachment options (detach straps or swap hooks), and a high-capacity hold on smooth, clean surfaces. Avoid relying on suction anchors for long-term exterior use in extreme heat or on textured/porous materials; for those situations choose mechanical fasteners or check surface compatibility first.
