Features: 45mm High Thrust Suction Cup Base delivers powerful adhesion for reciprocating motion machines, featuring ABS and vacuums lock technology for stable operations. The reinforced ABS suction base with red pressure plate ensures instantly vacuums sealing on smooth surfaces like temper glass, ceramic tiles, and toilet lid through simple lift press operations. Ideal for enthusiasts, mechanical engineers, and repair technicians requiring secure mounting solution for small reciprocating motion equipment in workshops or home projects. Perfect for precisions tasks requiring vibrations resistant fixtures from glass engraving machines to automated cleaning devices on not porous surfaces in bathrooms or industrial environments. Optimize performances with voltages adjustment maintain under 12V for prolonged use (middle ranges on adaptor) or boosts to 24V temporarily (<1minute) for high speed applications while ensuring equipment safety.
