Bal-tec™ Home The Riser Blocks
The standard four inch square Riser Blocks come in four different heights. The thinnest one (Part #10010) is four inches (10.2 cm) square by one inch (2.54 cm) thick. They are usually sold in sets of four pieces (Part #10020). The next thicker riser (Part #10030) is a four inch (10.2 cm) square by two inches (5.1 cm) thick. They are usually sold in sets of four pieces (Part #10040). The next thicker riser (Part #10050) is a four inch (10.2 cm) square by four inch (10.2 cm) forming a cube. They are usually sold in sets of four pieces (Part #10060). The longest or highest one (Part #10070) is four inches (10.2 cm) square by six inches (15.2 cm) long. They are usually sold in sets of four pieces (Part #10080). All of the Risers are manufactured from aircraft quality aluminum alloy for high strength and light weight.
Large pockets are cored out on both sides of the thicker risers. This greatly reduces the weight while preserving a very rigid structure. All Risers have a well distributed group of M10 × 1.5 threaded holes on three faces. Any of our M10 threaded fixture building components are directly compatible with all Risers. Any of our components using the high load carrying one half inch (1.3 cm) diameter joint are made compatible with the Risers by using the One Half Inch (1.3 cm) Diameter Counter-Bored Adaptor (Part #20010). This device has an M10 × 1.5 threaded hole on one side and a one half inch (1.3 cm) diameter counter-bore, with a #10-32 clamp down thread in the center of the bottom. The Risers can be solidly clamped to the C.M.M. table or pallet by standard Bar-Hold-Down Clamps inserted into the cored-out sides or by using the Vee Bar-Hold-Down Clamps over M10 × 1.5 screws with a short cylinder. A very unique feature of these risers is the vacuum hold down chuck that is built right into their bases. When the table of the C.M.M. is a continuous high quality plane, such as granite, these vacuum chucks can be used to firmly clamp the risers in place. On a good flat surface this vacuum chuck will provide 94 pounds (42 kg) of holding force.
