• Purpose: These are small, often round, plastic caps designed to push-fit into or over screw heads or pre-drilled mounting holes in the uPVC frame. They are used to:

  • Aesthetics: Conceal unsightly screw heads for a clean, finished look.

  • Protection: Prevent dirt and moisture from collecting in the screw heads or holes, which can lead to corrosion or degradation over time.

• Appearance: Usually simple, flat, or slightly domed round caps. They come in various diameters to fit different screw sizes (e.g., 6mm, 8mm, 10mm, 13mm, 15mm). Some have a little “lip” to snap over the screw head, while others push directly into a pre-drilled hole.

• Colors: Match the uPVC frame colors.

End Plugs/Caps for Channels or Profiles:

• Purpose: Sometimes, the term “holecap” might broadly refer to small end plugs that cap off the open ends of internal channels or specific profiles within the uPVC system, although these are usually more specifically called “end caps” or “channel plugs.”
