Payment
At 4 metres, the slightest wobble or play is enough to make you regret climbing up.
This telescopic ladder reaches a firm 4.4m, then folds down to 125cm, enough to reach high guttering, low rooflines or tree work, on a structure that doesn't shift underfoot.
Why this ladder
- Serious height: 4.4m for jobs out of reach of a standard ladder.
- Reinforced rigidity: high-strength aluminium stiles that don't flex at full extension.
- Secure locking: each section locked by an independent latch with a visible indicator.
- Controlled fold-down: progressive descent, finger-safe, stores at 125cm.
- EN131 standard: 150kg maximum load.
Who it's for: anyone who climbs regularly at height and is done with feeling a ladder shake underneath them.

OUR SAFETY MECHANISM
The SecureLock System
Every section locks in place with its own latch and a visible marker, confirming it's secured before you climb.
To fold down, each latch releases individually, no ambiguity before you climb, no unexpected drop while folding.
BUILT FOR STABILITY
Steady at Full Extension
Reinforced aluminium stiles hold their rigidity at maximum extension, while non-slip feet grip concrete, tile and packed earth.
A wider base lowers the centre of gravity, keeping the ladder steady from the first rung to the last.
