- Suction Cups
Spare suction cups for our shower perches or for whatever you want to use them for. They come with a pilot hole and a little 5/32" hanger bolt (not stainless steel) for attaching them. We recommend caution when attaching, it's easy to pierce the suction cup all the way through accidentally when you screw it on to the pointed end of the bolt. When we attach them to our shower perches we use pliars to screw the bolt into a pre-drilled hole (5/32" or 3.5-4mm) in the perch first, leaving just the right length of screw sticking out. THEN we screw on the suction cup.
Notes on Using Suction Cups:
These handy devices are designed to conform to the shape of the surface that they are stuck to, and will adhere best to surfaces that are smooth and non-porous, like metal or glass.
- Make sure the suction cup is clean and free from debris.
- If the suction cup needs to be cleaned, wash in warm soapy water then dry gently with a lint-free cloth.
- Clean the surface you are applying the suction cup to. It won't adhere well to a dirty surface.
- To enhance suction, a tiny dab of Vaseline or cooking oil may be rubbed on the rim of the cup.
- Press the cup all the way down, against the surface.
- The suction cup may need to be "burped" periodically by pressing down on it to remove any air that may have seeped in.
- Temperature and humidity variations may make a suction cup lose its grip. If bonded above 5â° C the cup will provide the most reliable service.
- To remove the cup, simply pull up on the release tab to break the suction.
