Chassis and bodywork

TR4, 4A, 250 & 5 SURREY TOPS AND HARDTOPS

Firstly, 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 roll‑over bar (ROB). 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. Surrey tops and all three types of roof panel can be used in the normal manner.

Whilst the arrangement is much stronger with a ROB incorporated, Revington TR also offer a 'standalone' fibreglass back light frame which is constructed of much thicker fibreglass and does not need a ROB. It should be noted that this configuration is not as strong as the original aluminium and certainly nowhere near as strong as the ROB supported part.

To complete the installation a fit up kit will be needed, these are found under the heading 'FIT UP KITS, ROOF PANELS & ACCESSORIES' . To this might be added a surrey top or a hard top.

So, a typical installation might include: -

1 x RTR7122-3BRK Backlight Frame and ROB

1 x RTR7172F Fit up kit with flexiglass window

1 x RTR6139BK Surrey top kit

Please Note: Our backlight frame with and without the ROB or full cage has successfully been fitted to TR6 as well.

RTR7153 TR4-6 Standalone Backlight Frame.

This backlight frame has no ROB and is untrimmed. This backlight frame includes the internal bosses to accept the stainless steel finishers through which a surrey top or hard top is attached.

RTR7122 Series TR4-6 Roll Over Bar with Backlight Frame.

The part numbers in the series RTR7122 incorporate one untrimmed fibreglass backlight frame and one ROB. The part number suffix dictates the type of ROB included in the package.

RTR7267 Series TR4-6 Full cage, 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, see below.
