Description
Window sill end caps anthracite in colour, sold as a pair: the Verge + Sill End Cap Anthracite (Pair) closes the open ends of the dark trims in this range — the anthracite over sills and the anthracite verge trim with upstand. One item is two caps, enough for both ends of one run.
Five Reasons to Choose This Pair
- Made for this range. The pair is listed for the anthracite over sills and the anthracite verge trim sold by Renders World, so the colour of cap and profile is the same.
- Two caps, one run. A single item closes the left and right end of one sill or one length of verge trim.
- A finished edge. The cap covers the cut end of the profile, so the run stops neatly at the reveal instead of showing an open section.
- One listing, one call. The range has a single anthracite pair; give the counter the depth of your sill and the pair is confirmed for that profile.
- A white twin. Where the frames are white, the same pair is listed in white for the white trims.
Window Sill End Caps Anthracite: What They Close
Each cap is an L-shaped closure: a long leg that ends in a rounded, downturned nose. Seen from the inside it has a channel that takes the end of the profile; seen from the outside it shows the anthracite face.

Match the Caps to Your Profile
Before you order, ring the counter on 023 8200 2442 and say which profile the caps are for: the over sill depth (110, 140, 170 or 220 mm) or the verge trim. The team confirms the pair for that profile before the order goes in.
How Many Pairs a Job Takes
Count the runs, not the metres.
- One window sill with both ends open takes one pair, however many 2.5 m lengths it is made of.
- A row of three separate windows takes three pairs.
- Each separate run of verge trim with two open ends takes one more pair.
Anthracite or White
The cap follows the colour of the trim it closes. Anthracite over sills and the anthracite verge trim take this pair; the white profiles take the white end cap pair.
Fitting the Caps
Two guides cover the work at the openings:
- How to install window sill extensions — measuring, cutting and closing a sill run.
- Render detailing around windows and doors — how sills, beads and render meet at the reveal.
Every sill, trim and cap in both colours is on the window sill extensions page.
