Check Before You Buy
This seal is suitable if:
- Your glass is 4mm, 5mm or 6mm thick
- The gap between the glass panels is around 3–13mm
- Your shower door is hinged or pivot-style
- The seal will be fitted to a straight, exposed glass edge
- You need a vertical side seal, not a bottom seal
- You need extra fin coverage for a wider side gap
- You need a seal up to 2000mm long
Before ordering, close the shower door and measure the gap between the two glass panels. This model has a 15mm soft fin, so it is intended for wider side gaps on thinner frameless glass.
Choose another seal if:
- Your glass is thinner than 4mm or thicker than 6mm
- The gap is below 3mm or above 13mm
- Your shower door is sliding, bi-fold, framed
- You need a seal for the bottom of the shower door
- The gap is between glass and wall, glass and tray, or inside a shower track
- A metal frame, trim or rail is blocking the glass edge
- You need a magnetic seal, drip seal, threshold seal or sliding door seal
If the door type or gap position is different, it is worth checking the full range of vertical shower seals before ordering.
Product Overview
The H456S15 is a clear push-fit shower door seal for 4–6mm frameless glass. It is mainly used as a vertical side seal between a moving shower door and a fixed glass panel.
This version has a longer 15mm soft fin, which is useful when the side gap is too wide for the shorter H456S8 seal. The fin reaches across the gap between the glass panels and helps reduce water spray during showering.
The clear PVC channel pushes onto the exposed glass edge without glue, screws or silicone.
The seal can usually be fitted to either the door panel or the fixed panel.
After fitting, open and close the shower door slowly. Check that the fin does not catch, fold back the wrong way, or stop the door from closing properly.
No glue, screws or silicone are required for normal installation.
FAQ
Is H456S15 suitable for 6mm shower glass?
Yes. H456S15 is made for frameless glass from 4mm to 6mm thick, including 4mm, 5mm and 6mm glass. It should not be used on 8–10mm glass, as the channel is made for thinner glass.
What kind of side gap is H456S15 made for?
H456S15 is for 4–6mm frameless glass where the side gap is more than a small hairline opening, but not large enough to need the longest fin sizes. It gives a little more coverage while still keeping the seal fairly discreet on the glass.
Can I use this instead of H810S15?
Only if your glass is 4–6mm thick. H456S15 has a 15mm fin, but the channel is made for thinner glass. For 8–10mm glass, choose H810S15.
Can I use this seal on a sliding shower door?
No. H456S15 is not made for sliding shower door edges or sliding door overlaps. It is mainly for hinged or pivot frameless shower doors where the seal sits vertically between two glass panels.

Care & Installation Tips
Ensure a better fit and longer-lasting clarity.
✓ DO’S
- Direct Press: Fit by pressing directly onto the glass edge to protect the surface.
- Deep Clean: Remove all UK hard-water limescale before installation.
- Sharp Tools: Use garden pruners for a clean, professional finish.
- Daily Rinse: Simply wash away soap suds after your shower.
✕ DON’TS
- No Sliding: Never slide the seal along the glass; this risks scratching.
- No Extreme Heat: Avoid water >70°C or hair dryers to prevent warping.
- No Soapy Water: Do not use lubricants—they accelerate mould growth.
- No Harsh Chemicals: Avoid bleach or acidic cleaners on the seal.
