VEVOR Glass Suction Cup, 254 mm 449 kg Capacity, Vacuum Suction Cup with Steel Handle & Carry Box, Heavy Duty Industrial Suction Cup Lifter Tool for Glass, Granite, Tile, Metal, Wood Panel Lifting

Could I use this on a regular internal ceiling to hang a 5KG light, permanently, or would it need to be re suctioned at various times?

Hi there, I’m looking at purchasing some suction lifting cups for handling fibreglass panels. I’d like to purchase 6 x GPS-1-10 and wondered if you sell them in twin packs like you do in the 8” (203mm) models? I’d rather go for the larger size if I could. Thanks Pat
