Will the MG003 Solve Your "Falling Seal" Problem?

The MG003 is our specialist 'Deep-Reach' model, engineered to anchor itself where others fail. Check these two measurements:

1
The 9mm T-Slot Width: Measure the horizontal opening of your aluminium groove. If it’s 9mm, the MG003 will slide in smoothly.
2
The 13mm T-Slot Depth: This is the game-changer. Measure how far back the groove goes into your frame. At 13mm deep, the MG003 provides an unparalleled mechanical grip that stays put, no matter how many times the door is opened.

Why Choose the MG003 Ultra-Deep Seal?
+

The MG003 is the 'heavy hitter' in our framed magnetic collection. It’s designed for premium UK enclosures that feature deep-set aluminium extrusions.

While standard strips only 'touch' the surface of the frame, the MG003’s 13mm deep insertion locks the magnet deep within the metal rail. This prevents the 'twisting' or 'rattling' often found in older or budget-fit showers. Delivering a powerful, watertight seal that feels solid and professional.

Care & Installation Tips

Ensure a better fit and longer-lasting clarity.

Ultra-Deep 9mm T-Slot Framed Shower Door Magnetic Strip (13mm Depth) MG003 Installation Guide - Simba Anti-Mould Shower Seal

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.

Through showerdoorseal.uk, we help customers find the right replacement seal by checking the glass thickness, gap size, seal profile, frame channel and shower door design.
