Designed with the professional installer in mind, ROBERTS Power-Lok Extendible Floor Roller is a must-have for the installation of sheet vinyl, VCT, and linoleum. It features a patented, spring-loaded metal collar that locks and quickly extends / retracts the length from 18" to 28" in seven fixed-lock set options. Recessed hardware protects against damage to floors or walls, and segmented rollers provide even pressure and maximum transfer of adhesive to the floorcovering for a finished look that is smooth and level. The wide and comfortable metal handgrip allows for body weight to be leveraged to press the flooring into the adhesive. The ergonomic, non-slip TPR handle is designed with a thumb rest for comfortable, extended use.
