Overview

An extension ladder is two sections that slide on each other, so it travels short and reaches long. It leans on the structure, which carries part of the load — unlike a step ladder it cannot stand on its own.

We rent 28 ft, 32 ft and 40 ft, the tallest we have. Gutters and roof access, exterior painting, high windows, and tree trimming with care.

Two numbers decide whether it is safe. The 4-to-1 rule: stand the base 1 ft out from the wall for every 4 ft of height. And when climbing onto a roof, extend it at least 3 ft above the roof edge, so there is something to hold at the top.

Check both rung locks are hooked over a rung before anyone climbs.

Best uses

  • Gutters and roof access
  • Exterior painting
  • High windows
  • Tree trimming (with care)

Troubleshooting

Fly section won't extend or lock

Checks to try, in order

  1. Pull the rope straight down and let the rung locks ride over the rungs.
  2. Lower it slightly until both locks hook onto the same rung.

Reference draft — always follow the manufacturer’s manual.

Feet slipping

Checks to try, in order

  1. Set the angle using the 4-to-1 rule.
  2. Swivel the feet: flat pads for hard surfaces, spurs for soft ground.

Reference draft — always follow the manufacturer’s manual.

Safety

  • Keep aluminium ladders well away from power lines — they conduct electricity.
  • Never stand on the top three rungs.

For manual / non-powered

  • Inspect for damage before every use and never exceed the rated load.
