Locking Rail (long)

In some kinds of cartridges for laser printers (HP LJ 4000, Canon EX) during regeneration process it is very important to separate the hopper and other cartridge parts. Unfortunately it is not the mechanical process (like unscrewing) but we have to unstick heated by factory parts (using a knife in most cases). In the future after the sealing and pouring the toner, we have to put cartridge together again. To this end we can apply plastic clips (rails). Locking rails tightly conform to the hopper flanges, eliminate sharp edges and do not disfigure the hopper. And they are designed for reuse. We can use long Locking Rail instead of few short clips, but sometimes the housing of cartridge makes impossible its using and we should apply some short metal clips.
Designed for use in laser printers.
