Lock into faster flooring installation
Flooring systems don’t come any faster or easier to fit. In i4F’s unique drop-lock system, two technologies come together to make one strong, high-performing floor.
3L TripleLock
The “original” one piece drop-lock system for the short side.
3L TripleLock is the easiest and fastest system for flooring installation on the market, and suitable for existing high speed production. Unlike other systems, no inserts are needed on the short side. That means less work, smaller costs, fewer materials and a lower carbon footprint.
Click4U
An angle system for the long-side, combined with 3L TripleLock on the short side.
Click4U works seamlessly with 3L TripleLock, enabling extremely high locking strength. Fast and easy to install, no special tools are needed – and it’s suitable for existing high speed production machinery.
WATER-RESISTANT TECHNOLOGY
Lock out water damage
Powered by i-Click4U®
With i4F you’re home and dry. i-Click4U® (impermeable-Click4U) is the world’s first ever water-resistant, one-piece, drop-lock flooring installation system, complementing i4F’s leading Click4U technology. Water-resistance is built into the installation system itself, so no extra chemical sprays or sealants are needed. i-Click4U has passed tests from independent institutes in France, Germany and the US, and exceeds all NALFA requirements related to water resistant flooring. With i4F you’re home and dry.

How it works
See how easy i4F’s unique drop-lock technologies make it to install and disassemble floorboards of any material.
i4F DROP-LOCK FOR HERRINGBONE
Perfect pattern change
i4F has launched a new, patented drop-lock system specifically designed for the installation of herringbone floor panels, whereby a panel‘s short side fits into the long side of an adjacent panel. The main advantage of this is that it enables easy installation, disassembly and replacements of panels in a herringbone pattern without compromising on high locking strength and performance.
