RetroGrip Tread20 is part of the retro fit range of products, designed and manufactured in the UK by GripDeck.
Unlike the original RetroGrip, Tread20 has a smooth base, which allows the treads to be fitted onto both smooth and grooved decking boards.
Available in 1m aluminium lengths with no minimum order, they are an easy, cost effective and attractive solution for solving a slippery decking problem.
It is recommended that you use Flexyfix to fix the Retrogrip Tread to your decking. More info can be found here
