⚡ At a Glance
- • Suction Power: Strong adsorption on smooth, non-porous surfaces, maintaining grip even in windy conditions according to user reports
- • Best for: Renters, crafters and shopkeepers needing temporary, non-damaging hanging solutions for signs and decorations

Transparent plastic suction pads come with metal screws and knurled nuts for screw-in hanging. A pack of 12 small 25mm cups suits multiple, compact mounting needs on smooth surfaces.
Secure hanging – with knurled nut and metal screw
Knurled nuts thread onto the top-mounted metal screw, creating a fixed anchor point above the suction pad. The screw-and-nut arrangement allows objects to be hung or secured directly from the threaded top.
A firm, mechanical connection reduces slippage when suspending lightweight signs or panels, so displays stay aligned and tidy.
Damage-free mounting – thanks to soft transparent plastic pads
Soft plastic pads form a vacuum seal when pressed onto a smooth, dry surface, expelling air to create adhesion. The material is described as waterproof and resistant to yellowing or deformation.
Pads leave no drilling holes or residue on glass and mirrors and can be removed by peeling the edge, preserving surfaces for renters and seasonal displays.
Versatile use across surfaces – with compact 25mm pads and a 12-piece set
Each suction cup measures about 25mm in diameter and is supplied in a set of 12, allowing placement across multiple positions or projects. The small size keeps mounts discreet while the quantity supports repeat or decorative installations.
Multiple compact cups allow even weight distribution for lightweight decorations and make it easy to reuse and reconfigure setups for events or shop displays.
