HUNTERSVILLE, N.C., Nov. 1, 2016 /PRNewswire/ -- IRWIN ® Tools, a leading manufacturer of hand tools and power tool accessories, announces the launch of an updated line of One-Handed Bar Clamps (OHBC) and introduces a new line of clamping accessories. The new lines feature upgraded clamps for improved ease of use and a complete line of OHBC accessories that extend the functionality of the redesigned Heavy-Duty (HD) and Medium-Duty (MD) OHBC to enable users to transform their OHBC into a specialty clamp allowing them to accomplish many tasks with just one tool. "As the creator of the first OHBC, IRWIN ® QUICK-GRIP ® is known for providing innovative clamping solutions, and by listening to our users, we understand how important it is for them to be able to use one tool for various tasks on the job," said Jillian Shute, Director of Brand Marketing, IRWIN ® Tools. "Our refreshed OHBC and new line of OHBC accessories were designed with that insight in mind. The new accessories extend the functionality of the OHBC and allow tradespeople to accomplish more tasks without the added cost and need for additional storage that comes with purchasing a brand new clamping tool." The updated clamping line includes a Quick-Change™ push button for easy conversion into a spreader or for quick installation of the new accessories, and the swivel jaws are now removable to allow users the flexibility to modify the jaw position based on what each job requires. Consistent with the previous generation of OHBC that tradespeople trust today, the new Heavy Duty and Medium Duty OHBC can sustain 600 and 300 pounds of clamping force, respectively. The Heavy-Duty clamps are available in six sizes (6", 12", 18", 24", 36", 50"), and the Medium-Duty clamps are available in five sizes (6", 12", 18", 24", 36"). The entire range also includes redesigned Mini and Micro clamps for a cohesive look and feel throughout the family of OHBC. The Mini is available in 6" and 12"; the Micro is available in 4-1/4."
