Introducing five heavy-duty one-handed bar clamps to complement the existing range of Eclipse one-handed bar clamps and spreaders, ideal for heavy-duty work-holding applications. Aluminum frames are lightweight but strong and durable. Allow much higher sustained clamping pressure than the existing Eclipse one-handed bar clamps. It is capable of achieving up to 300 kg of sustained holding force. Easy push button system allows quick change from clamping to spreading. Removable pads stay fixed to the clamp giving an even distribution of clamping force across the work piece protecting it from marking damage and insert trigger prevents accidental release.
