The Universal Cover Trim is used where timber or laminate joins another floor of the same level or slightly different height. Most often used where timber or laminate meets existing floor coverings such as stretch carpet, cork, tiles or other existing coverings that are slightly higher or lower than the flooring being installed or as an expansion trim for large area floors. To install the Universal Cover Trim, firstly the base plate is glued to the floor and then the correct plastic insert is slotted into the cover trim and then pushed into the base plate to Ã’clampÃ• down to the floor, once the flooring is installed. It has a 45mm top cover and is available in 3.4 mtr lengths. A base plate and insert is required. The 3.4mtr kits come with three inserts for all flooring thicknesses.
