Full details

Designed for professional contractors and DIY enthusiasts, these Plaslyne 85mm PVC window cill end caps provide a clean, weather-resistant finish to exposed cut ends. While they are engineered for a perfect fit on 85mm profiles, they are specific to this size and will not accommodate larger or smaller cill dimensions, making accurate measurement essential before purchase.

FAQs

Are these end caps suitable for interior use?

Yes, they can be used for interior cills, though they are specifically designed to withstand external weather conditions.

Do I need any special tools to install these?

No, they are designed for manual installation, though a small amount of adhesive is recommended for a secure fix.

Can these be painted?

While they are finished in a standard white, it is generally recommended to use them as-is to avoid paint flaking on plastic surfaces.

What is the material composition?

The end caps are made from high-grade, durable PVC, matching the standard material used for window cills.

How many caps come in a pack?

Each pack contains one pair, which covers both ends of one window cill.

Troubleshooting

Cap feels loose on the cill profile

Apply a small amount of PVC adhesive to the inside of the cap before pressing it firmly into place.

The cap does not fit the width of the cill

Verify that your cill profile is exactly 85mm; these caps are not compatible with larger or smaller standard profiles.

Pros and Cons

Pros

  • Provides a clean, professional aesthetic
  • Protects exposed PVC edges from dirt and moisture
  • Easy to install without specialized tools
  • Durable, long-lasting PVC construction

Cons

  • Compatibility limited strictly to 85mm profiles
  • May require adhesive for a permanent, high-traffic seal
  • Cannot be resized or modified easily

Setup, Compatibility & Care

To install, ensure your 85mm cill is cut squarely and the edges are free of burrs or excess PVC dust. For a secure fit, clean the surface of the cill with a mild solvent cleaner before attachment. While these are designed as a press-fit, applying a small bead of high-quality PVC superglue or silicone sealant to the inner rim can provide a permanent, weather-tight bond. For care, simply wipe the caps down during regular window cleaning with soap and water; avoid using abrasive scrubbers that could scratch the white finish.
