These Featherweight blocks provide convenient use and handling for your employees. The wide span of adjusting screw and nut assemblies have precision-cut Acme threads for extra strength and ease of use with a maximum static load of 5 tons. The 6061-T6511 high-strength aluminum body is machined to give you ultimate stiffness with maximum adjustability at a minimum weight. In fact, these blocks only weigh TWO pounds for the 12 inch model. The adjusting screw is easily moved by hand.

When you make it easy for your employees, they will use it! Safety practices quickly become a habit with the Sat-T-Block Featherweight Press Blocks.

• 5 ton maximum static load capacity
• Available in three sizes 
• Steel Holder and Electrical Cut-Off System also available

Please note:

• Many materials are available for use in blocking the ram and upper die of a press. 6061-T6 aluminum offers much higher extruded strength per cubic inch than any other know press safety block material on the market. When static load cpacity of the material is compared, aluminum becomes the clear choice.
• Use only certified material, preferably aluminum. Aluminum is malleable, and will deform. Magnesium is supposed to fracture at a 45 degree angle, but can fracture and cause shrapnel. Steel should never be considered due to potential shrapnel issues.
• .250" of daylight. Under no circumstances should there be more space between the top of the Die Safety Block and the die, or between the top of the Die Safety Block and the slide if the die is absent. It is absolutely critical to accurately calculate the needed Safety Die Block length. An opening greater than .250" changes the force of a moving slide from static to dynamic.
• If two Die Safety Blocks are needed, they should be placed at diagonal corners.
