8-10mm Heavy-Duty Shower Sliding Door Bottom Seal Gap 5-8mm SL810DTL

Struggling with water leaking through a wide gap (5-8mm) due to uneven flooring or a high threshold? The SL810DTL features extra-long, reinforced side fins specifically engineered to bridge these large distances without sagging. Compatible with 8-10mm thick glass and any shower door type, it is the ultimate solution for challenging installations where standard seals fail.

• Precision Fit for Modern Glass: Engineered specifically for 8mm, 9mm, and 10mm toughened glass. The rigid U-channel ensures a secure, "non-slip" grip that won't slide off over time.
• Intelligent Hybrid Design: Features a dual-hardness construction. The rigid body provides structural integrity, while the soft, side-orientated fin creates a watertight barrier without adding unnecessary friction.
• Low-Clearance Specialist: This is the ultimate solution for sliding doors with internal tracks or enclosures with a narrow 5mm to 8mm bottom gap. Because the fin originates from the side, it seals the gap without dragging against the tray or track.
• Smooth, Frictionless Operation: Unlike traditional vertical sweeps that can make doors feel "stiff," our soft-flex side fin ensures your door glides or swings freely—maintaining 100% water-tightness with zero sticking or straining.
• Virgin PVC Clarity: Manufactured from REACH-certified, anti-UV virgin PVC. Unlike cheap supermarket alternatives, SIMBA seals stay crystal clear, resist yellowing, and feature an anti-fungal additive to prevent mould build-up.

This model is a lifesaver for sliding shower doors. Many customers find that standard 'drip-fin' seals are too tall and get jammed in the bottom track. The side-mounted fin on the SL810DTL provides that crucial lateral seal, keeping the water inside the tray while allowing the rollers to move smoothly. If your gap is 5-8mm, this is your #1 choice.
