P&Pd Cattle Restraining Bar
Instruction Manual
Jaw adjustment: There are two pivot holes in the aluminium over- jaw. The hole furthest from the restraint’s handle end is ordinarily used for gripping 40NB (1½” ID / 48mm OD) pipe, and the hole closest to the handle end, is used for 50NB (2" ID / 60mm OD) pipe.
Note: 40NB pipe has a circumference of 151 mm
50NB pipe has a circumference of 189mm.
32NB pipe has a circumference of 132mm.
The pivot hole used for 40NB pipe can also be used for 32NB pipe, but for full time use on this size pipe we recommend that thicker friction pads be fitted, which we supply upon customer request ......
.... for use on 25NB pipe we can supply modified pads which allow the bar to be used on either 25NB or 40NB pipe by simply changing pivot hole positions.
The rail being gripped may be round or square, ie. thick plank, RHS rail, pipe rail.
In the picture shown the over-jaw is set to be used on 40NB pipe (or less).
The upper hole (closest to the restraint handle) is for 50NB pipe
Tethering:
Tethering is an option that may be employed when restraining cattle who display a “vigorous intention to evade containment”.... typically from heifers being introduced to the daily milking routine. The shock cord tether maintains an uninterrupted preload to the bar so that if an animal applies abrupt pressure to the jaw-end of the bar, the bar remains locked in place regardless of cattle movement (struggle).
There’s no real science, or complication to tethering to a bum- rail ( zig-zag or straight) , or stall rail...... but when some general principles are kept in mind it becomes an intuitive process.
Cross over on second pass
Above is the classic – shock cord loop over the rail - round and back up - over the first cord pass, then over- down- under and back, for the loop to be secured to one of three attachment points (in this case the hook). The start of the first pass may be from under the rail.....whatever works best for the operator..... The arrangements below employ the same principles as the above and are some of many:
These are the three attachment points to use: handle, knob, and hook
Tether length and component positions can be altered to operator preference:
Hook position can be changed.
Tether length can be altered for preference or to another rail size
The shock cord is connected to the bar by passing through the base of the attachment knob. By loosening the allen recessed capscrew back by10mm, the cord may be repositioned or removed completely.
The last basic principle with tethering is that the bar be always free to move rearwards as an animal places pressure on the main body. The only real impediment to this happening is if the “hook” is able to make contact with the rail being in a way that restricts bar movement.
In these examples the hook doesn’t impede rearwards bar movement and this is easily achieved..... Same for straight rails.
In a herringbone milking shed, the tethering feature is only intended for use in demanding situations such as when young stock are initiated into being regularly milked, and it’s use may be dispensed with after that.
Suggestions from users:
- one cattle restraining bar user found that the more determined of his Jersey heifers, finding that they couldn't budge the bar, would crawl underneath it. He solved this issue by attaching the bar to the kick rail instead of the zigzag rail and now escape by doing the "limbo" is no longer an option.......this approach worked perfectly for these smaller animals
Commendations:
- " I purchased 2 bars off you last year and would like to purchase 2 more. They are great, no slipping!"

"We had a cow that got stuck on bar after she jumped over it. I was away from shed when staff ph me to say they cant get her off, she is hanging over bar. My heart sank, a brand new bar will now surely be bend and stuffed! What a waste of money! When I got to shed after about 10 min she was hanging there like sack of s*** with full weight on bar. Then the BIG surprise! All we had to do was lift handle and slide it back into bar which then dropped to ground allowing the retard cow to walk off. BEST of all, NO damage to bar!!! Handle slides in and out perfectly! Now that is what I called a strong piece of equipment!"
