Thumb Screw Suction Cups - 43mm | Pack of 100

Description

What Is This Product?

The Thumb Screw Suction Cup is a 43mm clear PVC suction cup designed to hold signage against glass, acrylic and other smooth, non-porous surfaces without tools, adhesives or drilling. It grips by suction alone, so it can be lifted off, repositioned, or removed cleanly whenever a display changes.

Built into the face of each cup is a Galvanised Iron Screw Thread, giving you a fixing point to attach hanging cord, wire, or other display hardware once the cup is in place. It works as a two-step fixing: press the cup onto the surface, then thread on whatever you need to hang or hold your sign.

Each cup is supplied on its own, with the screw thread in place but without any cord or hook attached. It's best suited to smooth, clean, non-porous surfaces such as glass, acrylic, Perspex and PVC.

Key Benefits

• Tool-free fixing
  Presses onto glass or acrylic by suction alone, so there's no drilling, screwing into the surface, or waiting for adhesive to cure.
  
  
• Reusable and Repositionable
  Lift and reposition the cup as many times as needed, useful for seasonal displays or signage that changes often.
  
  
• Integrated Screw Thread
  The built-in galvanised iron screw gives you a ready-made point to attach cord, wire, or other hanging hardware.
  
  
• No Surface Damage
  Leaves glass and acrylic free of holes, screw marks or adhesive residue once removed.
  
  
• Clear finish
  The transparent PVC body sits discreetly against glass, so it doesn't distract from the sign or the surface behind it.
  
  
• Bulk Pack Size
  Supplied in packs of 100, which keeps unit costs down for large window and glazing projects.
  
  
• Wide Surface Compatibility
  Works on glass, acrylic, Perspex and other smooth, non-porous surfaces common in retail and exhibition settings.

How It Differs From Metal Hook Suction Cups

Harrison Products also stocks a Metal Hook Suction Cup, which is worth comparing if you're deciding between fixing styles.

• The Thumb Screw Suction Cup has a screw thread, so you choose and attach your own hanging cord, wire or fixing accessory.
  
  
• The Metal Hook Suction Cup has a fixed hook already built in, which suits signage with a hole or loop ready to hang straight onto it.
  
  
• Choose the screw thread version if you want flexibility over what you attach. Choose the hook version if you want something ready to hang from with no extra parts.

Required Accessories

This suction cup does not come with any hanging cord, wire or hook attached. The screw thread gives you a fixing point, but if you're hanging signage rather than just holding it flat against a window, you'll need to add the following separately:

• Hanging cord or wire, to run from the screw thread to your sign
• A compatible fixing accessory if your signage doesn't already have a hole or loop for hanging

Ideal Applications

These suction cups turn up across retail, exhibition, hospitality, office and event environments wherever signage needs to go up on glass or acrylic without tools. Typical uses include:

• Hanging price tags, promotional cards or swing tickets from shop windows
• Fixing lightweight signage to glazed partitions or acrylic screens in offices
• Mounting temporary window displays in retail units without drilling
• Creating quick hanging points for exhibition stands and event signage
• Attaching directional or wayfinding signs to glass doors and panels
