This packer has been designed to be used with PNR-12K Bar Rail Chair so that the chair can accommodate the smaller 10mm x 20mm Bar Rail.
The chair has been designed to be used either with our plastic 71/4″ Gauge sleeper (PNR-12i) or wooden sleepers. If used with our sleepers automatic gauge widening is built in.
Manufactured from a high grade polymer, the chair is of a compact design of pleasing appearance, embodying many full size features.
The system is very easy to assemble, push the bar into the chair, locate the chair onto the sleeper and screw down.
