Our 100 ft. open-reel long tape measure gives you the best accuracy and durability in its class. The open-reel tape measure features a nylon-coated steel tape with minimal stretch and resists kinks and tears when used in abusive conditions. The long tapes also feature the industry's first Grime Guard™ tape wiper, which prevents dirt, dust, and debris from entering the open reel and jamming it. Reinforced 3:1 planetary gearing and an all-metal frame ensure toughness when using your tape in the harshest job site conditions.
