Make sure your borders stay neat and in place with our Border or Ramp End Caps. Like our 2By2 Border Timbers, the Border Timber Filler End Caps are made from recycled structural plastic and come in both eight-inch and twelve-inch versions. They’re easy to install with your 2By2 Timbers and are made of durable, weather-resistant plastic to stand up to the elements and years of everyday wear and tear. Borders and ends help keep mulch and playground filler in place, maintaining the life of your rubber mulch and protective padding. Ask us about alternative shades and warranties, as well as installation.
