We have a limited stock of pre-owned aluminim splicing blocks for quarter-inch tape. These EMI produced blocks (known as "Emiblocks" when tape was in its heyday), are considered the best product for splicing. With no fiddly levers, the groove gripped the tape and allowed speedy and easy cutting of the tape in the 90, 60 and 45 degree angles. Sliding the two pieces of tape together to apply the splicing tape was easy too.
Being pre-owned they do have some scratches on them, caused by the steel razor blade, but they still do their intended job perfectly.
