TR2-3B Roll Over Bar. Right Hand Drive competition type with a removable diagonal and harness bar intended for wrap around harnesses (no ferrules). RevingtonTR's competition bars are designed for those who desire the extra rigidity of a diagonal brace for competition or track day use.

The bars are handed so that the strongest point is above the drivers head, this ROB has a diagonal running from top right to bottom left. The removable diagonal gives you the best of both worlds: the convenience of a non obstructed rear view and better use of the rear shelf, for general road use and the safety of a diagonally braced ROB for competition. For those who have no need for a removable diagonal or wish to save some cost then the fixed diagonal is for you RTR9047-2 series. This ROB kit includes an integral harness bar, many owners, whether using their car on the road or the track, will find the use of a harness both comfortable and reassuring. If you have chosen to fit a ROB it is generally considered better that in the unfortunate event of the car rolling over it is preferable to be firmly strapped in. A full harness will achieve this with much greater effect then a lap and diagonal arrangement. It is important to note that this ROB will not interfere with the operation of the hood on soft top cars.

See Section 9 'SEAT BELTS' for suitable seat belts products of the harness variety.

RevingtonTR Roll Over Protection (ROP) - The range 

RevingtonTR supply a full range of ROP including Roll Over Bars (ROB) and Full Roll Cages for the complete TR range. All ROB's allow the hood to be folded and unfolded and a hard top to be fitted unless specified otherwise. The following descriptions are used to describe the style of bars in our range.

ROAD BARS have no diagonal brace and have the option, to special order only of an integral, transverse harness bar.

COMPETITION BARS are supplied with fixed (RTR9047-2 series) or removable (RTR9047-3 series) diagonal brace, and have the option, to special order only, of a transverse harness bar.

Our preferred option for all our TTR2-3B ROB's is to supply a ROB with no harness bar and one of our stand alone harness bars as this provides far more flexibility and additional space in the cockpit. 

Please see below for other ROBs available for your car.

Our range of ROP's is extensive, to help you decide what is best for you we have compiled an information sheet in an easy to follow tablature format. Please see IS0040 here or via the 'Further Reading' tab above.

Will this ROB give me adequate protection?

Neil Revington provides some insight: - 

All ROB's in the RTR9047 series are attached to the wheel arches as can be seen in the photographs. Whist there are bars available with a main hoop that attaches to the chassis, they impede seat and hood sticks movement in many cases. What is more important is the data relating to accidents.

Things to consider.

The ROB's in this RTR9047 series  have a main hoop and back stays that are secured to the body (rear wheel arches), all main mountings of our full cages are attached to the chassis. Yes, attaching all mountings to the chassis would be fundamentally better but by how much? Fitting any one of the ROP's in our range is a good idea, choosing the right one is a matter of personal choice of how much 'cotton wool' to wrap yourself in.

The results of the actual events highlighted below show that wheel arch mounted ROB's provide adequate protection; full cages are available for those that feel a cage is the solution for them.

The original concept of this design can be attributed to John Aley of Aley bars in the 1970's. A very early bar was fitted to John Welburn's black TR2 which he then rolled at Goodwood. There are photos of John, arms flaying as he rolled over and over. John walked away with no injuries. The bar was intact, the wheel arches dented but the bar nonetheless saved John's life. A few year later Frank Richardson had a similar unfortunate roll in qualifying for a TR Register race. In this case, Frank was also thankfully OK, the wheel arches were not damaged and the car, after a few dents were knocked out, raced the next day.

Please Note: The various photographs available to view here show bars with and without harness bars and a diagonal brace for reference. The basic concept of the main hoop and backstays remains the same throughout the range.
