The CSUNIV-500 reusable stainless steel external locking rails have been specifically designed for use with HP 4000 and related remanufactured cartridges. The locking rails rejoin the mag roller and hopper sections. Black in color, these rails are virtually invisible against the cartridge.

Two types of locking rails, long and short, are available from Static Control. Long rails require only one rail per side, while four rails per side are recommended if using the short rails. Both offer excellent holding power and multiple cycle life, the choice is yours. Rails are pre-stamped for easy cartridge type identification, eliminating confusion and streamlining your production process.
