The HSE requirement for levelling is clearly stated: “Only use a ladder if the rungs are level. Ladders can be levelled using specially designed devices but NOT by using bits of brick or whatever else is at hand.”

The Levellers attach to each stile at the bottom of the ladder and provide swift adjustment for slopes in both directions (left to right or right to left) of up to 75mm in increments of 3mm. This is sufficient adjustment for the maximum recommended slope of 16 degrees.

Levellers are fitted with sticky rubber feet at the base to cope with back-slip.
