TR4-5 Full cage, fixed diagonal RHD with Backlight Frame.
This full cage is neat and unobtrusive; it incorporates a set of legs to join from the cabin to the chassis. See RTR9177 series in section 9 for a fuller description. The front hoop goes down the side of the dash panel, requiring a small amount to be removed from each side. Revington TR do not approve of mutilating perfectly good original dash panel. To alleviate this problem we supply a solid aluminium panel, which can be adjusted to suit. Order Part no. RTR6133:
To clarify the correct description of Hardtops and Surrey Tops, although the general arrangement of fixed rear window with removable roof panel is generally referred to as a 'Surrey Top' car, this is in fact not correct. The cloth section, which replaces the roof panel, is the 'Surrey Top'. The rear window and frame is called the 'back light' and the roof panel is self-explanatory.
Revington TR has developed an ingenious new Backlight design, which incorporates a full cage, with complete convenience. The Backlight frame is made from fibreglass, but uses for its strength an integral ROB with two backstays. The bar fits right up inside the fibreglass frame, thus affording maximum rollover protection, along with better rear visibility than with any other rollover bar available for use with a fixed backlight. The legs of the main hoop extend to the floor, whilst two rear stays attach to the top of the rear wheel arches. The main hoop is bolted to the 'B' posts too for added rigidity.
These cages comprise front and rear hoops, removable door and roof bars, harness bar and diagonal. 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.
Surrey tops and all three types of roof panel can be used in the normal manner.
These bars have been cleverly designed with sliding feet to accommodate different shapes and sizes of car; this will allow the main hoop of the ROB to fit neatly up inside the 'top hat' section of the backlight frame. Once the correct height has been established the sleeve is bolted firmly in place.
Please note that the front hoop goes down the side of the dash panel, requiring a small amount to be removed from each side. Revington TR do not approve of mutilating perfectly good original dash panel. To alleviate this problem we supply a solid aluminium panel, which can be adjusted to suit. Order Part no. RTR6133.
