The Jorgensen 6-Inch Heavy-Duty Steel Bar Clamp is easy to open and close, making it ideal for clamping in small areas. The sliding head moves easily up and down the bar, and the adjustable action is solid and fast. This clamp has a 6-inch opening capacity, a 3-inch reach, and a 1,000-pound load limit. The strong yet lightweight steel bars are plated to be rust resistant, and the clamp can be depended upon for long-term use.
