Strong, secure suction mount for smooth, non‑porous surfaces Key benefits Strong, secure grip: 15.2 cm suction cup provides firm attachment to smooth, non‑porous surfaces such as countertops, glass and metal, ensuring reliable hold on cars, boats, RVs and other vehicles. No drilling required: integrated M8 internal thread on top of the suction base lets you mount devices and accessories without cutting or drilling holes, saving time and preserving surfaces. Heavy‑duty capacity: supports up to 31.8 kg, designed to handle heavy loads and provide dependable support for a wide range of mounted equipment. Easy vacuum check and activation: pump the piston a few times to create suction; the red line indicator disappears when sufficient vacuum is reached, giving a clear visual confirmation of a secure seal. Features and specifications Suction cup diameter: 15.2 cm Top connection: integrated M8 internal thread Maximum load capacity: 31.8 kg Surface compatibility: smooth, non‑porous surfaces (glass, metal, sealed stone, finished countertops, vehicle bodywork) Vacuum activation: manual piston pump; red line vacuum indicator How it solves problems Eliminates the need to drill holes or use permanent fasteners, so you can mount and reposition equipment without damaging surfaces. Clear vacuum indicator removes guesswork — you know when the mount is secure before use. High load capacity reduces risk of failure under heavier equipment or dynamic loads during travel. Typical use scenarios Vehicle mounting: attach monitoring equipment, lights or accessories temporarily to cars, boats or RVs without drilling into body panels. Workshop and home: mount tools or fixtures to finished countertops, glass panels or metal work surfaces for temporary tasks or testing. On‑the‑go setups: quickly install and remove devices for inspections, photography or fieldwork where a strong, non‑permanent mount is required. Installation and use tips Clean and dry the mounting surface before applying the suction cup for best adhesion. Place the cup flat against the surface, pump the piston a few times, and confirm the red line has disappeared to ensure sufficient vacuum. Periodically check the vacuum indicator during prolonged use and re‑pump if necessary. This suction mount combines a large 15.2 cm cup, an M8 threaded top for device attachment, a clear vacuum indicator and a 31.8 kg load rating to deliver a practical, non‑permanent mounting solution for vehicles, boats, RVs and other smooth, non‑porous surfaces.
