- What it is and includes: A wooden floor mounting kit that helps position and lock planks in place for tongue-and-groove systems. It contains a pull bar, an impact block, and 20 spacers to prevent damage during installation. - Key benefits: Protects boards from dents and impact, enables precise gaps, and facilitates tight fittings without marring the surface. The 20 spacers supply flexible gap control for proper expansion. - Easy to use: Use two spacers in the floor installation tool to adjust gap thickness. Place washers at the edges and leave enough space to expand if necessary. - Practical operation: The pull rod helps eliminate gaps along the long side of boards. When joining two boards, insert the tapping block into the spring of the board to assist tapping and seating. - Material and durability: Made of PP+iron, providing a strong and durable tool for laying wooden and laminate floors with tongue-and-groove locking systems. - Use scenarios: Ideal for installing laminate or engineered wood floors in living rooms, hallways, or bedrooms where consistent gaps and edge protection are important. Suitable for DIY projects and professional installations requiring repeatable, damage-free results. Works with standard tongue-and-groove locking systems to improve alignment and finish.
