⚠️ Pro-fit measurement tip
- Check the reach: This 18mm bulb is significantly larger than standard seals. Please ensure you have at least 14mm of clearance to allow the door to close comfortably.
- T-post check: Confirm your frame groove is 7mm wide. If you have a narrower 5mm or 6mm groove, the base will not fit.
Why choose BU003? (The problem solver) Tap to expand +
- Close the uncloseable: Is your shower door sagging or misaligned? Standard seals can't reach the frame, but our 18mm jumbo bulb bridges the widest gaps that others can't touch.
- Maximum water block: Designed for high-flow power showers where standard seals let "splash-back" escape through oversized gaps.
- Structural buffer: Acts as a heavy-duty shock absorber, preventing heavy glass doors from slamming against metal frames.
- Crystal clear & anti-mould: Despite its size, it remains discreet and transparent, infused with the same antimicrobial shield as our entire range.
