I need two suction cup lifter heads that have a can be attached to a custom handle. The heads (together) need to be able to hold around 60-100 lbs and must adhere to fiberglass, glass, or other materials that boat hulls are manufactured from. Waterproof suction cups that have lever action suction and won't leave UV marks , etc would be ideal.If you can't find more Buying Leads related to your items, why not post your Selling Leads and Products instead?
