Where should springs be?
Safely out of harm’s way… CarTeck extension springs are high up, out of reach of inquisitive fingers in covered trays.
Goodbye ugly torsion springs
How often do you see rusty torsion springs and what effect does it have on performance?
What looks neater? Extension springs, of course, concealed and protected from corrosion in steel trays with lids.
Extension spring are better
If you were choosing and up and over door, what sort would you put on your own home? – Probably a retractable door. What counterbalance does that use? ...Extension springs.
It is a fact that extension springs deliver their energy in a much more linear fashion giving a better balanced door – even on doubles. CarTeck trays also keep the springs in pristine condition, ensuring long-term smooth and quiet operation.
Surely you lose headroom?
No sacrifice on headroom either - fit CarTeck and a CarTeck DRIVE in just 120mm - low headroom as standard on 95%+ of all door sizes! This only increases to 140mm when double springing is needed on the very tallest and widest doors.
Spring safety - 4 cables Vs anti-drop devices
CarTeck springs are held by 4 cables as standard - this means that, should a cable fail, three remain, which is sufficient to close the door and allow a planned repair.
By comparison, how complicated in practice are the anti-drop devices commonly used on torsion springs? When a torsion spring anti-drop device engages, the door stops functioning. It leaves customers making an emergency repair call and their property at risk because the door can’t be closed.
Nothing to get wrong
When surveying for a door, you can’t pick the wrong gear when there is only one to choose from! Rear torsion, front torsion, low headroom torsion, side extension springs… plenty to get mixed up there… Choose CarTeck and high-level extension springs every time!
As you’d expect our doors and openers are independently tested and certified to all current safety legislation and carry a CE mark.
