The Fusion™ Carpet Seam Weight has been engineered to make perfect seams every time. It was designed by installers to perform better than any other seam weight or tool box! 12-lb (5.44 kg) weight sets carpet seam in place while the seam cools, but will not leave a profile on carpet. 363 vent holes for quicker cooling. 6½” x 13″ (16.52 cm x 33 cm) vented heavy-duty plastic base provides full pressure for even wide seam tape jobs and will not get hot, warp or rust.
