The Mid-Weight Adjustable Safety Block is produced to the same standards used for manufacturing both our Light-Weight and larger Standard safety press blocks.
The Mid-Weight Adjustable series has been successfully tested by an outside third party laboratory. This series is specifically engineered to be used between our Light-Weight adjustable press block LSB-1B & 2B - rated at 35 tons, and our Standard SB-1 adjustable rated at 125 tons.
The Mid-Weight series is available from 10" to 60" by the inch and has the option of having 5" up to 12" of screw adjustment. This design maintains a static load of up to 75 tons and this Mid-Weight block is easily stored in our optional holder that is ready to mount to your press. These blocks are also available with our electrical power cut-off system, adding safety to your press and for your employees. The size and weight makes it very easy for them to move the block assembly into and out of the press area.
The MID-WEIGHT Saf-T-Blocks come standard with a base plate. Base plates allow for stability where room permits.
These Mid-Weight models can normally be shipped within 48 hours A.R.O

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.
