The RAPID electric stapler has been a standard in the printing industry for years. It is the only machine that can be run in series. This means you can line up as many as you like, and activate them simultaneously with bump switch or the foot pedal control. Two, three, or more stitches in a booklet can then be done in one hit. The RAPID 106 can be operated in a FLAT or SADDLE position, and is capable of stapling from 2 to 50 sheets (20lb bond stock) (Old P/N ST6106). This machine uses 1/4" (666-6) and 5/16" (666-8) RAPID staples.
