Nothing as annoying as a ladder that starts whistling while you drive. The Dirks whistle stopper solves that in one go: you clip it onto the ladder and the whistling during transport is a thing of the past.
The whistle stopper is sold per piece, for either the right or the left side of your ladder. Want to close off both sides? Order one right and one left. Available in blue, yellow, red and black, so you can also use it to colour-code your ladders.
✓ No more whistling during transport
✓ Easy to clip onto your ladder
✓ Sold per piece, for right or left
✓ Four colours to recognise your ladders at a glance
