✓The Tickr TCH-8400 is a double cylinder floor spring built for heavier glass doors in commercial showrooms, hotels, restaurants, and high-traffic office entrances
✓Engineered to handle door weights up to 120 kg and door widths up to 1100 mm, the TCH-8400 is the workhorse of Tickr's floor spring range — the model dealers reach for when a single cylinder floor spring isn't enough but a maximum-capacity floor spring is overkill
✓**Built for heavier commercial glass doors**
✓The TCH-8400 is the right choice when the TCH-7400 isn't strong enough
✓With double cylinder construction and a 25 nm closing force, the TCH-8400 handles wide commercial entrance doors, hotel lobby doors, restaurant frontage glass, hospital ward partitions, and office building reception doors
✓Where lighter springs would struggle to close a 110 kg toughened glass door reliably in winter — when door seals contract and friction increases — the TCH-8400 delivers consistent, controlled closing across all seasons
