4 pack, Heavy Duty Vacuum Suction Cup Hooks Anchor with Straps ecuring, Strong Suction Cup Tie Downs, Camping Tarp Accessory as Car Side Awning,for Kitchen,Bathroom,Restroom,Jet Ski, Kayaks SUP

Adequate but completely made of plastic, even the latches. Not heavy duty but adequate for I'd say 25 to 40 lbs or so. Anything more & I'd be nervous.MADE IN CHINA

It is not a suction cup, it is silicone adhesive that looks like a suction cup

Using on my fiberglass camper top tho anchor shelter canopy works great

Excellent

Used then product to attach fencing to our motor home. Was disappointed to find out they were made in China

Strong grip, works on paint or glass.
