The Backer Rod is a compressable round cord for the filling of joints. It ensures the proper hold for any kind of sealants afterwards and prevents unwanted adhesion and tear of the sealant.
Because its made of closed cell foam, the backer road is water-proof and resistant against rot. It´s easy to handle due to of its good compression and high stretch.
All backer rods (except the 10mm version) do have a hollow core, to ensure the easiest and best fit.
Please notice that the price for the backer rod is shown per linear meter. If you want to order a certain length, please choose the similar quantity in your order. For example, when you want to buy 10 linear meter, please choose a quantity of 10.
