The ROBERTS Laminate and Floating Wood Flooring Installation Kit comes complete with a tapping block, pull bar and 50 wedge spacers, designed for the do-it-yourself installer. The wedge spacers provide the correct expansion gap at the perimeter of the room, while the tapping block and pull bar help make the installation a tight fit. This laminate flooring installation kit conveniently includes complete instructions on how to install laminate and floating wood flooring. For larger installations, multiple rooms or for the professional installer, you may want to upgrade to the Professional Pull Bar (model 10-18-8) and Professional Tapping Block (model 10-17-8), also available at The Home Depot.
